-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

-OpenEmbedded-Core and Yocto Project Maintainer Information
-==========================================================
-
-OpenEmbedded and Yocto Project work jointly together to maintain the metadata,
-layers, tools and sub-projects that make up their ecosystems.
-
-The projects operate through collaborative development. This currently takes
-place on mailing lists for many components as the "pull request on github"
-workflow works well for single or small numbers of maintainers but we have
-a large number, all with different specialisms and benefit from the mailing
-list review process. Changes therefore undergo peer review through mailing
-lists in many cases.
-
-This file aims to acknowledge people with specific skills/knowledge/interest
-both to recognise their contributions but also empower them to help lead and
-curate those components. Where we have people with specialist knowledge in
-particular areas, during review patches/feedback from these people in these
-areas would generally carry weight.
-
-This file is maintained in OE-Core but may refer to components that are separate
-to it if that makes sense in the context of maintainership. The README of specific
-layers and components should ultimately be definitive about the patch process and
-maintainership for the component.

+Poky
+====
+
+Poky is an integration of various components to form a complete prepackaged
+build system and development environment. It features support for building
+customised embedded device style images. There are reference demo images
+featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
+cross-architecture application development using QEMU emulation and a
+standalone toolchain and SDK with IDE integration.
+
+Additional information on the specifics of hardware that Poky supports
+is available in README.hardware. Further hardware support can easily be added
+in the form of layers which extend the systems capabilities in a modular way.
+
+As an integration layer Poky consists of several upstream projects such as 
+BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
+e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
+
+The Yocto Project has extensive documentation about the system including a 
+reference manual which can be found at:
+    http://yoctoproject.org/documentation
+
+OpenEmbedded-Core is a layer containing the core metadata for current versions
+of OpenEmbedded. It is distro-less (can build a functional image with
+DISTRO = "nodistro") and contains only emulated machine support.
+
+For information about OpenEmbedded, see the OpenEmbedded website:
+    http://www.openembedded.org/
+
+Where to Send Patches
+=====================
+
+As Poky is an integration repository (built using a tool called combo-layer),
+patches against the various components should be sent to their respective
+upstreams:
+
+bitbake:
+    Git repository: http://git.openembedded.org/bitbake/
+    Mailing list: bitbake-devel@lists.openembedded.org

+    Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp)
+    Mailing list: poky@yoctoproject.org
+
+Everything else should be sent to the OpenEmbedded Core mailing list.  If in
+doubt, check the oe-core git repository for the content you intend to modify.
+Before sending, be sure the patches apply cleanly to the current oe-core git
+repository.
+
+    Git repository: http://git.openembedded.org/openembedded-core/

+                          ====================
+
+This file gives details about using Poky with the reference machines
+supported out of the box. A full list of supported reference target machines
+can be found by looking in the following directories:
+
+   meta/conf/machine/
+   meta-yocto-bsp/conf/machine/
+
+If you are in doubt about using Poky/OpenEmbedded with your hardware, consult
+the documentation for your board/device.
+
+Support for additional devices is normally added by creating BSP layers - for
+more information please see the Yocto Board Support Package (BSP) Developer's
+Guide - documentation source is in documentation/bspguide or download the PDF
+from:
+
+   http://yoctoproject.org/documentation
+
+Support for physical reference hardware has now been split out into a
+meta-yocto-bsp layer which can be removed separately from other layers if not
+needed.
+
+
+QEMU Emulation Targets
+======================
+
+To simplify development, the build system supports building images to
+work with the QEMU emulator in system emulation mode. Several architectures
+are currently supported:
+
+  * ARM (qemuarm)
+  * x86 (qemux86)
+  * x86-64 (qemux86-64)
+  * PowerPC (qemuppc)
+  * MIPS (qemumips)
+
+Use of the QEMU images is covered in the Yocto Project Reference Manual.
+The appropriate MACHINE variable value corresponding to the target is given
+in brackets.
+
+
+Hardware Reference Boards
+=========================
+
+The following boards are supported by the meta-yocto-bsp layer:
+
+  * Texas Instruments Beaglebone (beaglebone)

+and is likely to work on many unlisted Atom/Core/Xeon based devices. The MACHINE
+type supports ethernet, wifi, sound, and Intel/vesa graphics by default in
+addition to common PC input devices, busses, and so on.
+
+Depending on the device, it can boot from a traditional hard-disk, a USB device,
+or over the network. Writing generated images to physical media is
+straightforward with a caveat for USB devices. The following examples assume the
+target boot device is /dev/sdb, be sure to verify this and use the correct
+device as the following commands are run as root and are not reversable.
+
+USB Device:
+  1. Build a live image. This image type consists of a simple filesystem
+     without a partition table, which is suitable for USB keys, and with the
+     default setup for the genericx86 machine, this image type is built
+     automatically for any image you build. For example:
+
+     $ bitbake core-image-minimal
+
+  2. Use the "dd" utility to write the image to the raw block device. For
+     example:
+
+     # dd if=core-image-minimal-genericx86.hddimg of=/dev/sdb
+
+  If the device fails to boot with "Boot error" displayed, or apparently
+  stops just after the SYSLINUX version banner, it is likely the BIOS cannot
+  understand the physical layout of the disk (or rather it expects a
+  particular layout and cannot handle anything else). There are two possible
+  solutions to this problem:
+
+  1. Change the BIOS USB Device setting to HDD mode. The label will vary by
+     device, but the idea is to force BIOS to read the Cylinder/Head/Sector
+     geometry from the device.
+
+  2. Use a ".wic" image with an EFI partition
+
+     a) With a default grub-efi bootloader:
+     # dd if=core-image-minimal-genericx86-64.wic of=/dev/sdb
+
+     b) Use systemd-boot instead
+     - Build an image with EFI_PROVIDER="systemd-boot" then use the above
+       dd command to write the image to a USB stick.

+Texas Instruments Beaglebone (beaglebone)
+=========================================
+
+The Beaglebone is an ARM Cortex-A8 development board with USB, Ethernet, 2D/3D
+accelerated graphics, audio, serial, JTAG, and SD/MMC. The Black adds a faster
+CPU, more RAM, eMMC flash and a micro HDMI port. The beaglebone MACHINE is
+tested on the following platforms:
+
+  o Beaglebone Black A6
+  o Beaglebone A6 (the original "White" model)
+
+The Beaglebone Black has eMMC, while the White does not. Pressing the USER/BOOT
+button when powering on will temporarily change the boot order. But for the sake
+of simplicity, these instructions assume you have erased the eMMC on the Black,
+so its boot behavior matches that of the White and boots off of SD card. To do
+this, issue the following commands from the u-boot prompt:
+
+    # mmc dev 1
+    # mmc erase 0 512
+
+To further tailor these instructions for your board, please refer to the
+documentation at http://www.beagleboard.org/bone and http://www.beagleboard.org/black
+
+From a Linux system with access to the image files perform the following steps:
+
+  1. Build an image. For example:
+
+     $ bitbake core-image-minimal
+
+  2. Use the "dd" utility to write the image to the SD card. For example:
+
+     # dd core-image-minimal-beaglebone.wic of=/dev/sdb
+
+  3. Insert the SD card into the Beaglebone and boot the board.
+
+Freescale MPC8315E-RDB (mpc8315e-rdb)
+=====================================
+
+The MPC8315 PowerPC reference platform (MPC8315E-RDB) is aimed at hardware and
+software development of network attached storage (NAS) and digital media server
+applications. The MPC8315E-RDB features the PowerQUICC II Pro processor, which
+includes a built-in security accelerator.
+
+(Note: you may find it easier to order MPC8315E-RDBA; this appears to be the
+same board in an enclosure with accessories. In any case it is fully
+compatible with the instructions given here.)
+
+Setup instructions
+------------------
+
+You will need the following:
+* NFS root setup on your workstation
+* TFTP server installed on your workstation
+* Straight-thru 9-conductor serial cable (DB9, M/F) connected from your 
+  PC to UART1
+* Ethernet connected to the first ethernet port on the board
+
+--- Preparation ---
+
+Note: if you have altered your board's ethernet MAC address(es) from the
+defaults, or you need to do so because you want multiple boards on the same
+network, then you will need to change the values in the dts file (patch
+linux/arch/powerpc/boot/dts/mpc8315erdb.dts within the kernel source). If
+you have left them at the factory default then you shouldn't need to do
+anything here.
+
+--- Booting from NFS root ---
+
+Load the kernel and dtb (device tree blob), and boot the system as follows:
+
+ 1. Get the kernel (uImage-mpc8315e-rdb.bin) and dtb (uImage-mpc8315e-rdb.dtb)
+    files from the tmp/deploy directory, and make them available on your TFTP
+    server.
+
+ 2. Connect the board's first serial port to your workstation and then start up
+    your favourite serial terminal so that you will be able to interact with
+    the serial console. If you don't have a favourite, picocom is suggested:
+
+  $ picocom /dev/ttyUSB0 -b 115200
+
+ 3. Power up or reset the board and press a key on the terminal when prompted
+    to get to the U-Boot command line
+
+ 4. Set up the environment in U-Boot:
+
+ => setenv ipaddr <board ip>
+ => setenv serverip <tftp server ip>
+ => setenv bootargs root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:255.255.255.0:mpc8315e:eth0:off console=ttyS0,115200
+
+ 5. Download the kernel and dtb, and boot:
+
+ => tftp 1000000 uImage-mpc8315e-rdb.bin
+ => tftp 2000000 uImage-mpc8315e-rdb.dtb
+ => bootm 1000000 - 2000000
+
+--- Booting from JFFS2 root ---
+
+ 1. First boot the board with NFS root.
+
+ 2. Erase the MTD partition which will be used as root:
+
+    $ flash_eraseall  /dev/mtd3
+
+ 3. Copy the JFFS2 image to the MTD partition:
+
+    $ flashcp core-image-minimal-mpc8315e-rdb.jffs2 /dev/mtd3
+
+ 4. Then reboot the board and set up the environment in U-Boot:
+
+    => setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttyS0,115200
+
+
+Ubiquiti Networks EdgeRouter Lite (edgerouter)
+==============================================
+
+The EdgeRouter Lite is part of the EdgeMax series. It is a MIPS64 router
+(based on the Cavium Octeon processor) with 512MB of RAM, which uses an
+internal USB pendrive for storage.
+
+Setup instructions
+------------------
+
+You will need the following:
+* RJ45 -> serial ("rollover") cable connected from your PC to the CONSOLE
+  port on the device
+* Ethernet connected to the first ethernet port on the board
+
+If using NFS as part of the setup process, you will also need:
+* NFS root setup on your workstation
+* TFTP server installed on your workstation (if fetching the kernel from
+  TFTP, see below).
+
+--- Preparation ---
+
+Build an image (e.g. core-image-minimal) using "edgerouter" as the MACHINE.
+In the following instruction it is based on core-image-minimal. Another target
+may be similiar with it.
+
+--- Booting from NFS root / kernel via TFTP ---
+
+Load the kernel, and boot the system as follows:
+
+ 1. Get the kernel (vmlinux) file from the tmp/deploy/images/edgerouter
+    directory, and make them available on your TFTP server.
+
+ 2. Connect the board's first serial port to your workstation and then start up
+    your favourite serial terminal so that you will be able to interact with
+    the serial console. If you don't have a favourite, picocom is suggested:
+
+  $ picocom /dev/ttyS0 -b 115200
+
+ 3. Power up or reset the board and press a key on the terminal when prompted
+    to get to the U-Boot command line
+
+ 4. Set up the environment in U-Boot:
+
+ => setenv ipaddr <board ip>
+ => setenv serverip <tftp server ip>
+
+ 5. Download the kernel and boot:
+
+ => tftp tftp $loadaddr vmlinux
+ => bootoctlinux $loadaddr coremask=0x3 root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:<netmask>:edgerouter:eth0:off mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
+
+--- Booting from USB disk ---
+
+To boot from the USB disk, you either need to remove it from the edgerouter
+box and populate it from another computer, or use a previously booted NFS
+image and populate from the edgerouter itself.
+
+Type 1: Use partitioned image
+-----------------------------
+
+Steps:
+
+ 1. Remove the USB disk from the edgerouter and insert it into a computer
+    that has access to your build artifacts.
+
+ 2. Flash the image.
+
+    # dd core-image-minimal-edgerouter.wic of=/dev/sdb
+
+ 3. Insert USB disk into the edgerouter and boot it.
+
+Type 2: NFS
+-----------
+
+Note: If you place the kernel on the ext3 partition, you must re-create the
+      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
+      cannot read the partition otherwise.
+
+      These boot instructions assume that you have recreated the ext3 filesystem with
+      128 byte inodes, you have an updated uboot or you are running and image capable
+      of making the filesystem on the board itself.
+
+
+ 1. Boot from NFS root
+
+ 2. Mount the USB disk partition 2 and then extract the contents of
+    tmp/deploy/core-image-XXXX.tar.bz2 into it.
+
+    Before starting, copy core-image-minimal-xxx.tar.bz2 and vmlinux into
+    rootfs path on your workstation.
+
+    and then,
+  
+      # mount /dev/sda2 /media/sda2
+      # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /media/sda2
+      # cp vmlinux /media/sda2/boot/vmlinux
+      # umount /media/sda2
+      # reboot
+
+ 3. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
+    command line:
+
+    # reboot
+
+ 4. Load the kernel and boot:
+
+      => ext2load usb 0:2 $loadaddr boot/vmlinux
+      => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

-Bitbake
-=======
-
-BitBake is a generic task execution engine that allows shell and Python tasks to be run
-efficiently and in parallel while working within complex inter-task dependency constraints.
-One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software
-stacks using a task-oriented approach.
-
-For information about Bitbake, see the OpenEmbedded website:
-    https://www.openembedded.org/
-
-Bitbake plain documentation can be found under the doc directory or its integrated
-html version at the Yocto Project website:
-    https://docs.yoctoproject.org
-
-Bitbake requires Python version 3.8 or newer.
-
-Contributing
-------------
-
-Please refer to our contributor guide here: https://docs.yoctoproject.org/contributor-guide/
-for full details on how to submit changes.
-
-As a quick guide, patches should be sent to bitbake-devel@lists.openembedded.org
-The git command to do that would be:
-
-    git send-email -M -1 --to bitbake-devel@lists.openembedded.org
-
-If you're sending a patch related to the BitBake manual, make sure you copy
-the Yocto Project documentation mailing list:

-Testing
--------
-
-Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions.
-You can run this with "bitbake-selftest". In particular the fetcher is well covered since
-it has so many corner cases. The datastore has many tests too. Testing with the testsuite is
-recommended before submitting patches, particularly to the fetcher and datastore. We also
-appreciate new test cases and may require them for more obscure issues.
-
-To run the tests "zstd" and "git" must be installed.
-
-The assumption is made that this testsuite is run from an initialized OpenEmbedded build
-environment (i.e. `source oe-init-build-env` is used). If this is not the case, run the
-testsuite as follows:
-
-    export PATH=$(pwd)/bin:$PATH
-    bin/bitbake-selftest
-
-The testsuite can alternatively be executed using pytest, e.g. obtained from PyPI (in this
-case, the PATH is configured automatically):

-The bind address may take one of the following formats:
-    unix://PATH         - Bind to unix domain socket at PATH
-    ws://ADDRESS:PORT   - Bind to websocket on ADDRESS:PORT
-    ADDRESS:PORT        - Bind to raw TCP socket on ADDRESS:PORT
-
-To bind to all addresses, leave the ADDRESS empty, e.g. "--bind :8686" or
-"--bind ws://:8686". To bind to a specific IPv6 address, enclose the address in
-"[]", e.g. "--bind [::1]:8686" or "--bind ws://[::1]:8686"
-
-Note that the default Anonymous permissions are designed to not break existing
-server instances when upgrading, but are not particularly secure defaults. If
-you want to use authentication, it is recommended that you use "--anon-perms
-@read" to only give anonymous users read access, or "--anon-perms @none" to
-give un-authenticated users no access at all.
-
-Setting "--anon-perms @all" or "--anon-perms @user-admin" is not allowed, since
-this would allow anonymous users to manage all users accounts, which is a bad
-idea.
-
-If you are using user authentication, you should run your server in websockets
-mode with an SSL terminating load balancer in front of it (as this server does
-not implement SSL). Otherwise all usernames and passwords will be transmitted
-in the clear. When configured this way, clients can connect using a secure
-websocket, as in "wss://SERVER:PORT"
-
-The following permissions are supported by the server:
-
-    @none       - No permissions
-    @read       - The ability to read equivalent hashes from the server
-    @report     - The ability to report equivalent hashes to the server
-    @db-admin   - Manage the hash database(s). This includes cleaning the
-                  database, removing hashes, etc.
-    @user-admin - The ability to manage user accounts. This includes, creating
-                  users, deleting users, resetting login tokens, and assigning

-release.
+The Makefile processes manual directories to create HTML, PDF,

-Additional information related to the Sphinx migration, and guidelines

+To build a manual, you run the make command and pass it the name

-Sphinx is written in Python. While it might work with Python2, for

-documentation with Python3.
-
-Sphinx might be available in your Linux distro packages repositories,
-however it is not recommend using distro packages, as they might be
-old versions, especially if you are using an LTS version of your
-distro. The recommended method to install Sphinx and all required
-dependencies is to use the Python Package Index (pip).
-
-To install all required packages run:
-
- $ pip3 install sphinx sphinx_rtd_theme pyyaml

-Execution
-=========
-
-|
-
-The primary purpose for running BitBake is to produce some kind of
-output such as a single installable package, a kernel, a software
-development kit, or even a full, board-specific bootable Linux image,
-complete with bootloader, kernel, and root filesystem. Of course, you
-can execute the ``bitbake`` command with options that cause it to
-execute single tasks, compile single recipe files, capture or clear
-data, or simply return information about the execution environment.
-
-This chapter describes BitBake's execution process from start to finish
-when you use it to create an image. The execution process is launched
-using the following command form::
-
-  $ bitbake target
-
-For information on
-the BitBake command and its options, see ":ref:`The BitBake Command
-<bitbake-user-manual-command>`" section.
-
-.. note::
-
-   Prior to executing BitBake, you should take advantage of available
-   parallel thread execution on your build host by setting the
-   :term:`BB_NUMBER_THREADS` variable in
-   your project's ``local.conf`` configuration file.
-
-   A common method to determine this value for your build host is to run
-   the following::
-
-     $ grep processor /proc/cpuinfo
-
-   This command returns
-   the number of processors, which takes into account hyper-threading.
-   Thus, a quad-core build host with hyper-threading most likely shows
-   eight processors, which is the value you would then assign to
-   :term:`BB_NUMBER_THREADS`.
-
-   A possibly simpler solution is that some Linux distributions (e.g.
-   Debian and Ubuntu) provide the ``ncpus`` command.
-
-Parsing the Base Configuration Metadata
-=======================================
-
-The first thing BitBake does is parse base configuration metadata. Base
-configuration metadata consists of your project's ``bblayers.conf`` file
-to determine what layers BitBake needs to recognize, all necessary
-``layer.conf`` files (one from each layer), and ``bitbake.conf``. The
-data itself is of various types:
-
--  **Recipes:** Details about particular pieces of software.
-
--  **Class Data:** An abstraction of common build information (e.g. how to
-   build a Linux kernel).
-
--  **Configuration Data:** Machine-specific settings, policy decisions,
-   and so forth. Configuration data acts as the glue to bind everything
-   together.
-
-The ``layer.conf`` files are used to construct key variables such as
-:term:`BBPATH` and :term:`BBFILES`.
-:term:`BBPATH` is used to search for configuration and class files under the
-``conf`` and ``classes`` directories, respectively. :term:`BBFILES` is used
-to locate both recipe and recipe append files (``.bb`` and
-``.bbappend``). If there is no ``bblayers.conf`` file, it is assumed the
-user has set the :term:`BBPATH` and :term:`BBFILES` directly in the environment.
-
-Next, the ``bitbake.conf`` file is located using the :term:`BBPATH` variable
-that was just constructed. The ``bitbake.conf`` file may also include
-other configuration files using the ``include`` or ``require``
-directives.
-
-Prior to parsing configuration files, BitBake looks at certain
-variables, including:
-
--  :term:`BB_ENV_PASSTHROUGH`
--  :term:`BB_ENV_PASSTHROUGH_ADDITIONS`
--  :term:`BB_PRESERVE_ENV`
--  :term:`BB_ORIGENV`
--  :term:`BITBAKE_UI`
-
-The first four variables in this list relate to how BitBake treats shell
-environment variables during task execution. By default, BitBake cleans
-the environment variables and provides tight control over the shell
-execution environment. However, through the use of these first four
-variables, you can apply your control regarding the environment
-variables allowed to be used by BitBake in the shell during execution of
-tasks. See the
-":ref:`bitbake-user-manual/bitbake-user-manual-metadata:Passing Information Into the Build Task Environment`"
-section and the information about these variables in the variable
-glossary for more information on how they work and on how to use them.
-
-The base configuration metadata is global and therefore affects all
-recipes and tasks that are executed.
-
-BitBake first searches the current working directory for an optional
-``conf/bblayers.conf`` configuration file. This file is expected to
-contain a :term:`BBLAYERS` variable that is a
-space-delimited list of 'layer' directories. Recall that if BitBake
-cannot find a ``bblayers.conf`` file, then it is assumed the user has
-set the :term:`BBPATH` and :term:`BBFILES` variables directly in the
-environment.
-
-For each directory (layer) in this list, a ``conf/layer.conf`` file is
-located and parsed with the :term:`LAYERDIR` variable
-being set to the directory where the layer was found. The idea is these
-files automatically set up :term:`BBPATH` and other
-variables correctly for a given build directory.
-
-BitBake then expects to find the ``conf/bitbake.conf`` file somewhere in
-the user-specified :term:`BBPATH`. That configuration file generally has
-include directives to pull in any other metadata such as files specific
-to the architecture, the machine, the local environment, and so forth.
-
-Only variable definitions and include directives are allowed in BitBake
-``.conf`` files. Some variables directly influence BitBake's behavior.
-These variables might have been set from the environment depending on
-the environment variables previously mentioned or set in the
-configuration files. The ":ref:`bitbake-user-manual/bitbake-user-manual-ref-variables:Variables Glossary`"
-chapter presents a full list of
-variables.
-
-After parsing configuration files, BitBake uses its rudimentary
-inheritance mechanism, which is through class files, to inherit some
-standard classes. BitBake parses a class when the inherit directive
-responsible for getting that class is encountered.
-
-The ``base.bbclass`` file is always included. Other classes that are
-specified in the configuration using the
-:term:`INHERIT` variable are also included. BitBake
-searches for class files in a ``classes`` subdirectory under the paths
-in :term:`BBPATH` in the same way as configuration files.
-
-A good way to get an idea of the configuration files and the class files
-used in your execution environment is to run the following BitBake
-command::
-
-  $ bitbake -e > mybb.log
-
-Examining the top of the ``mybb.log``
-shows you the many configuration files and class files used in your
-execution environment.
-
-.. note::
-
-   You need to be aware of how BitBake parses curly braces. If a recipe
-   uses a closing curly brace within the function and the character has
-   no leading spaces, BitBake produces a parsing error. If you use a
-   pair of curly braces in a shell function, the closing curly brace
-   must not be located at the start of the line without leading spaces.
-
-   Here is an example that causes BitBake to produce a parsing error::
-
-      fakeroot create_shar() {
-         cat << "EOF" > ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
-      usage()
-      {
-         echo "test"
-         ######  The following "}" at the start of the line causes a parsing error ######
-      }
-      EOF
-      }
-
-      Writing the recipe this way avoids the error:
-      fakeroot create_shar() {
-         cat << "EOF" > ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
-      usage()
-      {
-         echo "test"
-         ###### The following "}" with a leading space at the start of the line avoids the error ######
-       }
-      EOF
-      }
-
-Locating and Parsing Recipes
-============================
-
-During the configuration phase, BitBake will have set
-:term:`BBFILES`. BitBake now uses it to construct a
-list of recipes to parse, along with any append files (``.bbappend``) to
-apply. :term:`BBFILES` is a space-separated list of available files and
-supports wildcards. An example would be::
-
-  BBFILES = "/path/to/bbfiles/*.bb /path/to/appends/*.bbappend"
-
-BitBake parses each
-recipe and append file located with :term:`BBFILES` and stores the values of
-various variables into the datastore.
-
-.. note::
-
-   Append files are applied in the order they are encountered in BBFILES.
-
-For each file, a fresh copy of the base configuration is made, then the
-recipe is parsed line by line. Any inherit statements cause BitBake to
-find and then parse class files (``.bbclass``) using
-:term:`BBPATH` as the search path. Finally, BitBake
-parses in order any append files found in :term:`BBFILES`.
-
-One common convention is to use the recipe filename to define pieces of
-metadata. For example, in ``bitbake.conf`` the recipe name and version
-are used to set the variables :term:`PN` and
-:term:`PV`::
-
-   PN = "${@bb.parse.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"
-   PV = "${@bb.parse.vars_from_file(d.getVar('FILE', False),d)[1] or '1.0'}"
-
-In this example, a recipe called "something_1.2.3.bb" would set
-:term:`PN` to "something" and :term:`PV` to "1.2.3".
-
-By the time parsing is complete for a recipe, BitBake has a list of
-tasks that the recipe defines and a set of data consisting of keys and
-values as well as dependency information about the tasks.
-
-BitBake does not need all of this information. It only needs a small
-subset of the information to make decisions about the recipe.
-Consequently, BitBake caches the values in which it is interested and
-does not store the rest of the information. Experience has shown it is
-faster to re-parse the metadata than to try and write it out to the disk
-and then reload it.
-
-Where possible, subsequent BitBake commands reuse this cache of recipe
-information. The validity of this cache is determined by first computing
-a checksum of the base configuration data (see
-:term:`BB_HASHCONFIG_IGNORE_VARS`) and
-then checking if the checksum matches. If that checksum matches what is
-in the cache and the recipe and class files have not changed, BitBake is
-able to use the cache. BitBake then reloads the cached information about
-the recipe instead of reparsing it from scratch.
-
-Recipe file collections exist to allow the user to have multiple
-repositories of ``.bb`` files that contain the same exact package. For
-example, one could easily use them to make one's own local copy of an
-upstream repository, but with custom modifications that one does not
-want upstream. Here is an example::
-
-  BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb"
-  BBFILE_COLLECTIONS = "upstream local"
-  BBFILE_PATTERN_upstream = "^/stuff/openembedded/"
-  BBFILE_PATTERN_local = "^/stuff/openembedded.modified/"
-  BBFILE_PRIORITY_upstream = "5"
-  BBFILE_PRIORITY_local = "10"
-
-.. note::
-
-   The layers mechanism is now the preferred method of collecting code.
-   While the collections code remains, its main use is to set layer
-   priorities and to deal with overlap (conflicts) between layers.
-
-.. _bb-bitbake-providers:
-
-Providers
-=========
-
-Assuming BitBake has been instructed to execute a target and that all
-the recipe files have been parsed, BitBake starts to figure out how to
-build the target. BitBake looks through the :term:`PROVIDES` list for each
-of the recipes. A :term:`PROVIDES` list is the list of names by which the
-recipe can be known. Each recipe's :term:`PROVIDES` list is created
-implicitly through the recipe's :term:`PN` variable and
-explicitly through the recipe's :term:`PROVIDES`
-variable, which is optional.
-
-When a recipe uses :term:`PROVIDES`, that recipe's functionality can be
-found under an alternative name or names other than the implicit :term:`PN`
-name. As an example, suppose a recipe named ``keyboard_1.0.bb``
-contained the following::
-
-  PROVIDES += "fullkeyboard"
-
-The :term:`PROVIDES`
-list for this recipe becomes "keyboard", which is implicit, and
-"fullkeyboard", which is explicit. Consequently, the functionality found
-in ``keyboard_1.0.bb`` can be found under two different names.
-
-.. _bb-bitbake-preferences:
-
-Preferences
-===========
-
-The :term:`PROVIDES` list is only part of the solution for figuring out a
-target's recipes. Because targets might have multiple providers, BitBake
-needs to prioritize providers by determining provider preferences.
-
-A common example in which a target has multiple providers is
-"virtual/kernel", which is on the :term:`PROVIDES` list for each kernel
-recipe. Each machine often selects the best kernel provider by using a
-line similar to the following in the machine configuration file::
-
-  PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"
-
-The default :term:`PREFERRED_PROVIDER` is the provider
-with the same name as the target. BitBake iterates through each target
-it needs to build and resolves them and their dependencies using this
-process.
-
-Understanding how providers are chosen is made complicated by the fact
-that multiple versions might exist for a given provider. BitBake
-defaults to the highest version of a provider. Version comparisons are
-made using the same method as Debian. You can use the
-:term:`PREFERRED_VERSION` variable to
-specify a particular version. You can influence the order by using the
-:term:`DEFAULT_PREFERENCE` variable.
-
-By default, files have a preference of "0". Setting
-:term:`DEFAULT_PREFERENCE` to "-1" makes the recipe unlikely to be used
-unless it is explicitly referenced. Setting :term:`DEFAULT_PREFERENCE` to
-"1" makes it likely the recipe is used. :term:`PREFERRED_VERSION` overrides
-any :term:`DEFAULT_PREFERENCE` setting. :term:`DEFAULT_PREFERENCE` is often used
-to mark newer and more experimental recipe versions until they have
-undergone sufficient testing to be considered stable.
-
-When there are multiple "versions" of a given recipe, BitBake defaults
-to selecting the most recent version, unless otherwise specified. If the
-recipe in question has a
-:term:`DEFAULT_PREFERENCE` set lower than
-the other recipes (default is 0), then it will not be selected. This
-allows the person or persons maintaining the repository of recipe files
-to specify their preference for the default selected version.
-Additionally, the user can specify their preferred version.
-
-If the first recipe is named ``a_1.1.bb``, then the
-:term:`PN` variable will be set to "a", and the
-:term:`PV` variable will be set to 1.1.
-
-Thus, if a recipe named ``a_1.2.bb`` exists, BitBake will choose 1.2 by
-default. However, if you define the following variable in a ``.conf``
-file that BitBake parses, you can change that preference::
-
-  PREFERRED_VERSION_a = "1.1"
-
-.. note::
-
-   It is common for a recipe to provide two versions -- a stable,
-   numbered (and preferred) version, and a version that is automatically
-   checked out from a source code repository that is considered more
-   "bleeding edge" but can be selected only explicitly.
-
-   For example, in the OpenEmbedded codebase, there is a standard,
-   versioned recipe file for BusyBox, ``busybox_1.22.1.bb``, but there
-   is also a Git-based version, ``busybox_git.bb``, which explicitly
-   contains the line ::
-
-     DEFAULT_PREFERENCE = "-1"
-
-   to ensure that the
-   numbered, stable version is always preferred unless the developer
-   selects otherwise.
-
-.. _bb-bitbake-dependencies:
-
-Dependencies
-============
-
-Each target BitBake builds consists of multiple tasks such as ``fetch``,
-``unpack``, ``patch``, ``configure``, and ``compile``. For best
-performance on multi-core systems, BitBake considers each task as an
-independent entity with its own set of dependencies.
-
-Dependencies are defined through several variables. You can find
-information about variables BitBake uses in the
-:doc:`bitbake-user-manual-ref-variables` near the end of this manual. At a
-basic level, it is sufficient to know that BitBake uses the
-:term:`DEPENDS` and
-:term:`RDEPENDS` variables when calculating
-dependencies.
-
-For more information on how BitBake handles dependencies, see the
-:ref:`bitbake-user-manual/bitbake-user-manual-metadata:Dependencies`
-section.
-
-.. _ref-bitbake-tasklist:
-
-The Task List
-=============
-
-Based on the generated list of providers and the dependency information,
-BitBake can now calculate exactly what tasks it needs to run and in what
-order it needs to run them. The
-:ref:`bitbake-user-manual/bitbake-user-manual-execution:executing tasks`
-section has more information on how BitBake chooses which task to
-execute next.
-
-The build now starts with BitBake forking off threads up to the limit
-set in the :term:`BB_NUMBER_THREADS`
-variable. BitBake continues to fork threads as long as there are tasks
-ready to run, those tasks have all their dependencies met, and the
-thread threshold has not been exceeded.
-
-It is worth noting that you can greatly speed up the build time by
-properly setting the :term:`BB_NUMBER_THREADS` variable.
-
-As each task completes, a timestamp is written to the directory
-specified by the :term:`STAMP` variable. On subsequent
-runs, BitBake looks in the build directory within ``tmp/stamps`` and
-does not rerun tasks that are already completed unless a timestamp is
-found to be invalid. Currently, invalid timestamps are only considered
-on a per recipe file basis. So, for example, if the configure stamp has
-a timestamp greater than the compile timestamp for a given target, then
-the compile task would rerun. Running the compile task again, however,
-has no effect on other providers that depend on that target.
-
-The exact format of the stamps is partly configurable. In modern
-versions of BitBake, a hash is appended to the stamp so that if the
-configuration changes, the stamp becomes invalid and the task is
-automatically rerun. This hash, or signature used, is governed by the
-signature policy that is configured (see the
-:ref:`bitbake-user-manual/bitbake-user-manual-execution:checksums (signatures)`
-section for information). It is also
-possible to append extra metadata to the stamp using the
-``[stamp-extra-info]`` task flag. For example, OpenEmbedded uses this
-flag to make some tasks machine-specific.
-
-.. note::
-
-   Some tasks are marked as "nostamp" tasks. No timestamp file is
-   created when these tasks are run. Consequently, "nostamp" tasks are
-   always rerun.
-
-For more information on tasks, see the
-:ref:`bitbake-user-manual/bitbake-user-manual-metadata:tasks` section.
-
-Executing Tasks
-===============
-
-Tasks can be either a shell task or a Python task. For shell tasks,
-BitBake writes a shell script to
-``${``\ :term:`T`\ ``}/run.do_taskname.pid`` and then
-executes the script. The generated shell script contains all the
-exported variables, and the shell functions with all variables expanded.
-Output from the shell script goes to the file
-``${``\ :term:`T`\ ``}/log.do_taskname.pid``. Looking at the expanded shell functions in
-the run file and the output in the log files is a useful debugging
-technique.
-
-For Python tasks, BitBake executes the task internally and logs
-information to the controlling terminal. Future versions of BitBake will
-write the functions to files similar to the way shell tasks are handled.
-Logging will be handled in a way similar to shell tasks as well.
-
-The order in which BitBake runs the tasks is controlled by its task
-scheduler. It is possible to configure the scheduler and define custom
-implementations for specific use cases. For more information, see these
-variables that control the behavior:
-
--  :term:`BB_SCHEDULER`
-
--  :term:`BB_SCHEDULERS`
-
-It is possible to have functions run before and after a task's main
-function. This is done using the ``[prefuncs]`` and ``[postfuncs]``
-flags of the task that lists the functions to run.
-
-.. _checksums:
-
-Checksums (Signatures)
-======================
-
-A checksum is a unique signature of a task's inputs. The signature of a
-task can be used to determine if a task needs to be run. Because it is a
-change in a task's inputs that triggers running the task, BitBake needs
-to detect all the inputs to a given task. For shell tasks, this turns
-out to be fairly easy because BitBake generates a "run" shell script for
-each task and it is possible to create a checksum that gives you a good
-idea of when the task's data changes.
-
-To complicate the problem, some things should not be included in the
-checksum. First, there is the actual specific build path of a given task
-- the working directory. It does not matter if the working directory
-changes because it should not affect the output for target packages. The
-simplistic approach for excluding the working directory is to set it to
-some fixed value and create the checksum for the "run" script. BitBake
-goes one step better and uses the
-:term:`BB_BASEHASH_IGNORE_VARS` variable
-to define a list of variables that should never be included when
-generating the signatures.
-
-Another problem results from the "run" scripts containing functions that
-might or might not get called. The incremental build solution contains
-code that figures out dependencies between shell functions. This code is
-used to prune the "run" scripts down to the minimum set, thereby
-alleviating this problem and making the "run" scripts much more readable
-as a bonus.
-
-So far we have solutions for shell scripts. What about Python tasks? The
-same approach applies even though these tasks are more difficult. The
-process needs to figure out what variables a Python function accesses
-and what functions it calls. Again, the incremental build solution
-contains code that first figures out the variable and function
-dependencies, and then creates a checksum for the data used as the input
-to the task.
-
-Like the working directory case, situations exist where dependencies
-should be ignored. For these cases, you can instruct the build process
-to ignore a dependency by using a line like the following::
-
-  PACKAGE_ARCHS[vardepsexclude] = "MACHINE"
-
-This example ensures that the
-``PACKAGE_ARCHS`` variable does not depend on the value of ``MACHINE``,
-even if it does reference it.
-
-Equally, there are cases where we need to add dependencies BitBake is
-not able to find. You can accomplish this by using a line like the
-following::
-
-  PACKAGE_ARCHS[vardeps] = "MACHINE"
-
-This example explicitly
-adds the ``MACHINE`` variable as a dependency for ``PACKAGE_ARCHS``.
-
-Consider a case with in-line Python, for example, where BitBake is not
-able to figure out dependencies. When running in debug mode (i.e. using
-``-DDD``), BitBake produces output when it discovers something for which
-it cannot figure out dependencies.
-
-Thus far, this section has limited discussion to the direct inputs into
-a task. Information based on direct inputs is referred to as the
-"basehash" in the code. However, there is still the question of a task's
-indirect inputs --- the things that were already built and present in the
-build directory. The checksum (or signature) for a particular task needs
-to add the hashes of all the tasks on which the particular task depends.
-Choosing which dependencies to add is a policy decision. However, the
-effect is to generate a master checksum that combines the basehash and
-the hashes of the task's dependencies.
-
-At the code level, there are a variety of ways both the basehash and the
-dependent task hashes can be influenced. Within the BitBake
-configuration file, we can give BitBake some extra information to help
-it construct the basehash. The following statement effectively results
-in a list of global variable dependency excludes --- variables never
-included in any checksum. This example uses variables from OpenEmbedded
-to help illustrate the concept::
-
-   BB_BASEHASH_IGNORE_VARS ?= "TMPDIR FILE PATH PWD BB_TASKHASH BBPATH DL_DIR \
-       SSTATE_DIR THISDIR FILESEXTRAPATHS FILE_DIRNAME HOME LOGNAME SHELL \
-       USER FILESPATH STAGING_DIR_HOST STAGING_DIR_TARGET COREBASE PRSERV_HOST \
-       PRSERV_DUMPDIR PRSERV_DUMPFILE PRSERV_LOCKDOWN PARALLEL_MAKE \
-       CCACHE_DIR EXTERNAL_TOOLCHAIN CCACHE CCACHE_DISABLE LICENSE_PATH SDKPKGSUFFIX"
-
-The previous example excludes the work directory, which is part of
-``TMPDIR``.
-
-The rules for deciding which hashes of dependent tasks to include
-through dependency chains are more complex and are generally
-accomplished with a Python function. The code in
-``meta/lib/oe/sstatesig.py`` shows two examples of this and also
-illustrates how you can insert your own policy into the system if so
-desired. This file defines the basic signature generator
-OpenEmbedded-Core uses: "OEBasicHash". By default, there
-is a dummy "noop" signature handler enabled in BitBake. This means that
-behavior is unchanged from previous versions. ``OE-Core`` uses the
-"OEBasicHash" signature handler by default through this setting in the
-``bitbake.conf`` file::
-
-  BB_SIGNATURE_HANDLER ?= "OEBasicHash"
-
-The main feature of the "OEBasicHash" :term:`BB_SIGNATURE_HANDLER` is that
-it adds the task hash to the stamp files. Thanks to this, any metadata
-change will change the task hash, automatically causing the task to be run
-again. This removes the need to bump :term:`PR` values, and changes to
-metadata automatically ripple across the build.
-
-It is also worth noting that the end result of signature
-generators is to make some dependency and hash information available to
-the build. This information includes:
-
--  ``BB_BASEHASH_task-``\ *taskname*: The base hashes for each task in the
-   recipe.
-
--  ``BB_BASEHASH_``\ *filename:taskname*: The base hashes for each
-   dependent task.
-
--  :term:`BB_TASKHASH`: The hash of the currently running task.
-
-It is worth noting that BitBake's "-S" option lets you debug BitBake's
-processing of signatures. The options passed to -S allow different
-debugging modes to be used, either using BitBake's own debug functions
-or possibly those defined in the metadata/signature handler itself. The
-simplest parameter to pass is "none", which causes a set of signature
-information to be written out into ``STAMPS_DIR`` corresponding to the
-targets specified. The other currently available parameter is
-"printdiff", which causes BitBake to try to establish the most recent
-signature match it can (e.g. in the sstate cache) and then run
-compare the matched signatures to determine the stamps and delta
-where these two stamp trees diverge. This can be used to determine why
-tasks need to be re-run in situations where that is not expected.
-
-.. note::
-
-   It is likely that future versions of BitBake will provide other
-   signature handlers triggered through additional "-S" parameters.

-section.
-
-Setscene
-========
-
-The setscene process enables BitBake to handle "pre-built" artifacts.
-The ability to handle and reuse these artifacts allows BitBake the
-luxury of not having to build something from scratch every time.
-Instead, BitBake can use, when possible, existing build artifacts.
-
-BitBake needs to have reliable data indicating whether or not an
-artifact is compatible. Signatures, described in the previous section,
-provide an ideal way of representing whether an artifact is compatible.
-If a signature is the same, an object can be reused.
-
-If an object can be reused, the problem then becomes how to replace a
-given task or set of tasks with the pre-built artifact. BitBake solves
-the problem with the "setscene" process.
-
-When BitBake is asked to build a given target, before building anything,
-it first asks whether cached information is available for any of the
-targets it's building, or any of the intermediate targets. If cached
-information is available, BitBake uses this information instead of
-running the main tasks.
-
-BitBake first calls the function defined by the
-:term:`BB_HASHCHECK_FUNCTION` variable
-with a list of tasks and corresponding hashes it wants to build. This
-function is designed to be fast and returns a list of the tasks for
-which it believes in can obtain artifacts.
-
-Next, for each of the tasks that were returned as possibilities, BitBake
-executes a setscene version of the task that the possible artifact
-covers. Setscene versions of a task have the string "_setscene" appended
-to the task name. So, for example, the task with the name ``xxx`` has a
-setscene task named ``xxx_setscene``. The setscene version of the task
-executes and provides the necessary artifacts returning either success
-or failure.
-
-As previously mentioned, an artifact can cover more than one task. For
-example, it is pointless to obtain a compiler if you already have the
-compiled binary. To handle this, BitBake calls the
-:term:`BB_SETSCENE_DEPVALID` function for
-each successful setscene task to know whether or not it needs to obtain
-the dependencies of that task.
-
-You can find more information on setscene metadata in the
-:ref:`bitbake-user-manual/bitbake-user-manual-metadata:task checksums and setscene`
-section.
-
-Logging
-=======
-
-In addition to the standard command line option to control how verbose
-builds are when execute, bitbake also supports user defined
-configuration of the `Python
-logging <https://docs.python.org/3/library/logging.html>`__ facilities
-through the :term:`BB_LOGCONFIG` variable. This
-variable defines a JSON or YAML `logging
-configuration <https://docs.python.org/3/library/logging.config.html>`__
-that will be intelligently merged into the default configuration. The
-logging configuration is merged using the following rules:
-
--  The user defined configuration will completely replace the default
-   configuration if top level key ``bitbake_merge`` is set to the value
-   ``False``. In this case, all other rules are ignored.
-
--  The user configuration must have a top level ``version`` which must
-   match the value of the default configuration.
-
--  Any keys defined in the ``handlers``, ``formatters``, or ``filters``,
-   will be merged into the same section in the default configuration,
-   with the user specified keys taking replacing a default one if there
-   is a conflict. In practice, this means that if both the default
-   configuration and user configuration specify a handler named
-   ``myhandler``, the user defined one will replace the default. To
-   prevent the user from inadvertently replacing a default handler,
-   formatter, or filter, all of the default ones are named with a prefix
-   of "``BitBake.``"
-
--  If a logger is defined by the user with the key ``bitbake_merge`` set
-   to ``False``, that logger will be completely replaced by user
-   configuration. In this case, no other rules will apply to that
-   logger.
-
--  All user defined ``filter`` and ``handlers`` properties for a given
-   logger will be merged with corresponding properties from the default
-   logger. For example, if the user configuration adds a filter called
-   ``myFilter`` to the ``BitBake.SigGen``, and the default configuration
-   adds a filter called ``BitBake.defaultFilter``, both filters will be
-   applied to the logger
-
-As a first example, you can create a ``hashequiv.json`` user logging
-configuration file to log all Hash Equivalence related messages of ``VERBOSE``
-or higher priority to a file called ``hashequiv.log``::
-
-   {
-       "version": 1,
-       "handlers": {
-           "autobuilderlog": {
-               "class": "logging.FileHandler",
-               "formatter": "logfileFormatter",
-               "level": "DEBUG",
-               "filename": "hashequiv.log",
-               "mode": "w"
-           }
-       },
-       "formatters": {
-               "logfileFormatter": {
-                   "format": "%(name)s: %(levelname)s: %(message)s"
-               }
-       },
-       "loggers": {
-           "BitBake.SigGen.HashEquiv": {
-               "level": "VERBOSE",
-               "handlers": ["autobuilderlog"]
-           },
-           "BitBake.RunQueue.HashEquiv": {
-               "level": "VERBOSE",
-               "handlers": ["autobuilderlog"]
-           }
-       }
-   }
-
-Then set the :term:`BB_LOGCONFIG` variable in ``conf/local.conf``::
-
-   BB_LOGCONFIG = "hashequiv.json"
-
-Another example is this ``warn.json`` file to log all ``WARNING`` and
-higher priority messages to a ``warn.log`` file::
-
-  {
-      "version": 1,
-      "formatters": {
-          "warnlogFormatter": {
-              "()": "bb.msg.BBLogFormatter",
-              "format": "%(levelname)s: %(message)s"
-          }
-      },
-
-      "handlers": {
-          "warnlog": {
-              "class": "logging.FileHandler",
-              "formatter": "warnlogFormatter",
-              "level": "WARNING",
-              "filename": "warn.log"
-          }
-      },
-
-      "loggers": {
-          "BitBake": {
-              "handlers": ["warnlog"]
-          }
-      },
-
-      "@disable_existing_loggers": false
-  }
-
-Note that BitBake's helper classes for structured logging are implemented in
-``lib/bb/msg.py``.

+
+    <para>
+        The primary purpose for running BitBake is to produce some kind
+        of output such as a single installable package, a kernel, a software
+        development kit, or even a full, board-specific bootable Linux image,
+        complete with bootloader, kernel, and root filesystem.
+        Of course, you can execute the <filename>bitbake</filename>
+        command with options that cause it to execute single tasks,
+        compile single recipe files, capture or clear data, or simply
+        return information about the execution environment.
+    </para>
+
+    <para>
+        This chapter describes BitBake's execution process from start
+        to finish when you use it to create an image.
+        The execution process is launched using the following command
+        form:
+        <literallayout class='monospaced'>
+     $ bitbake <replaceable>target</replaceable>
+        </literallayout>
+        For information on the BitBake command and its options,
+        see
+        "<link linkend='bitbake-user-manual-command'>The BitBake Command</link>"
+        section.
+        <note>
+            <para>
+                Prior to executing BitBake, you should take advantage of available
+                parallel thread execution on your build host by setting the
+                <link linkend='var-BB_NUMBER_THREADS'><filename>BB_NUMBER_THREADS</filename></link>
+                variable in your project's <filename>local.conf</filename>
+                configuration file.
+            </para>
+
+            <para>
+                A common method to determine this value for your build host is to run
+                the following:
+                <literallayout class='monospaced'>
+     $ grep processor /proc/cpuinfo
+                </literallayout>
+                This command returns the number of processors, which takes into
+                account hyper-threading.
+                Thus, a quad-core build host with hyper-threading most likely
+                shows eight processors, which is the value you would then assign to
+                <filename>BB_NUMBER_THREADS</filename>.
+            </para>
+
+            <para>
+                A possibly simpler solution is that some Linux distributions
+                (e.g. Debian and Ubuntu) provide the <filename>ncpus</filename> command.

+
+        <para>
+            The first thing BitBake does is parse base configuration
+            metadata.
+            Base configuration metadata consists of your project's
+            <filename>bblayers.conf</filename> file to determine what
+            layers BitBake needs to recognize, all necessary
+            <filename>layer.conf</filename> files (one from each layer),
+            and <filename>bitbake.conf</filename>.
+            The data itself is of various types:
+            <itemizedlist>
+                <listitem><para><emphasis>Recipes:</emphasis>
+                    Details about particular pieces of software.

+                    together.</para></listitem>
+            </itemizedlist>
+        </para>
+
+        <para>
+            The <filename>layer.conf</filename> files are used to
+            construct key variables such as
+            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
+            and
+            <link linkend='var-BBFILES'><filename>BBFILES</filename></link>.
+            <filename>BBPATH</filename> is used to search for
+            configuration and class files under the
+            <filename>conf</filename> and <filename>classes</filename>
+            directories, respectively.
+            <filename>BBFILES</filename> is used to locate both recipe
+            and recipe append files
+            (<filename>.bb</filename> and <filename>.bbappend</filename>).
+            If there is no <filename>bblayers.conf</filename> file,
+            it is assumed the user has set the <filename>BBPATH</filename>
+            and <filename>BBFILES</filename> directly in the environment.
+        </para>
+
+        <para>
+            Next, the <filename>bitbake.conf</filename> file is located
+            using the <filename>BBPATH</filename> variable that was
+            just constructed.
+            The <filename>bitbake.conf</filename> file may also include other
+            configuration files using the
+            <filename>include</filename> or
+            <filename>require</filename> directives.
+        </para>
+
+        <para>
+            Prior to parsing configuration files, Bitbake looks

+            </itemizedlist>
+            The first four variables in this list relate to how BitBake treats shell
+            environment variables during task execution.
+            By default, BitBake cleans the environment variables and provides tight
+            control over the shell execution environment.
+            However, through the use of these first four variables, you can
+            apply your control regarding the
+            environment variables allowed to be used by BitBake in the shell
+            during execution of tasks.
+            See the
+            "<link linkend='passing-information-into-the-build-task-environment'>Passing Information Into the Build Task Environment</link>"
+            section and the information about these variables in the
+            variable glossary for more information on how they work and
+            on how to use them.
+        </para>
+
+        <para>
+            The base configuration metadata is global
+            and therefore affects all recipes and tasks that are executed.
+        </para>
+
+        <para>
+            BitBake first searches the current working directory for an
+            optional <filename>conf/bblayers.conf</filename> configuration file.
+            This file is expected to contain a
+            <link linkend='var-BBLAYERS'><filename>BBLAYERS</filename></link>
+            variable that is a space-delimited list of 'layer' directories.
+            Recall that if BitBake cannot find a <filename>bblayers.conf</filename>
+            file, then it is assumed the user has set the <filename>BBPATH</filename>
+            and <filename>BBFILES</filename> variables directly in the environment.
+        </para>
+
+        <para>
+            For each directory (layer) in this list, a <filename>conf/layer.conf</filename>
+            file is located and parsed with the
+            <link linkend='var-LAYERDIR'><filename>LAYERDIR</filename></link>
+            variable being set to the directory where the layer was found.
+            The idea is these files automatically set up
+            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
+            and other variables correctly for a given build directory.
+        </para>
+
+        <para>
+            BitBake then expects to find the <filename>conf/bitbake.conf</filename>
+            file somewhere in the user-specified <filename>BBPATH</filename>.
+            That configuration file generally has include directives to pull
+            in any other metadata such as files specific to the architecture,
+            the machine, the local environment, and so forth.
+        </para>
+
+        <para>
+            Only variable definitions and include directives are allowed
+            in BitBake <filename>.conf</filename> files.
+            Some variables directly influence BitBake's behavior.
+            These variables might have been set from the environment
+            depending on the environment variables previously
+            mentioned or set in the configuration files.
+            The
+            "<link linkend='ref-variables-glos'>Variables Glossary</link>"
+            chapter presents a full list of variables.
+        </para>
+
+        <para>
+            After parsing configuration files, BitBake uses its rudimentary
+            inheritance mechanism, which is through class files, to inherit
+            some standard classes.
+            BitBake parses a class when the inherit directive responsible
+            for getting that class is encountered.
+        </para>
+
+        <para>
+            The <filename>base.bbclass</filename> file is always included.
+            Other classes that are specified in the configuration using the
+            <link linkend='var-INHERIT'><filename>INHERIT</filename></link>
+            variable are also included.
+            BitBake searches for class files in a
+            <filename>classes</filename> subdirectory under
+            the paths in <filename>BBPATH</filename> in the same way as
+            configuration files.
+        </para>
+
+        <para>
+            A good way to get an idea of the configuration files and
+            the class files used in your execution environment is to
+            run the following BitBake command:
+            <literallayout class='monospaced'>
+     $ bitbake -e > mybb.log
+            </literallayout>
+            Examining the top of the <filename>mybb.log</filename>
+            shows you the many configuration files and class files
+            used in your execution environment.
+        </para>
+
+        <note>
+            <para>
+                You need to be aware of how BitBake parses curly braces.
+                If a recipe uses a closing curly brace within the function and
+                the character has no leading spaces, BitBake produces a parsing
+                error.
+                If you use a pair of curly braces in a shell function, the
+                closing curly brace must not be located at the start of the line
+                without leading spaces.
+            </para>
+
+            <para>

+            During the configuration phase, BitBake will have set
+            <link linkend='var-BBFILES'><filename>BBFILES</filename></link>.
+            BitBake now uses it to construct a list of recipes to parse,
+            along with any append files (<filename>.bbappend</filename>)
+            to apply.
+            <filename>BBFILES</filename> is a space-separated list of
+            available files and supports wildcards.
+            An example would be:
+            <literallayout class='monospaced'>
+     BBFILES = "/path/to/bbfiles/*.bb /path/to/appends/*.bbappend"
+            </literallayout>
+            BitBake parses each recipe and append file located
+            with <filename>BBFILES</filename> and stores the values of
+            various variables into the datastore.
+            <note>
+                Append files are applied in the order they are encountered in

+            </note>
+            For each file, a fresh copy of the base configuration is
+            made, then the recipe is parsed line by line.
+            Any inherit statements cause BitBake to find and
+            then parse class files (<filename>.bbclass</filename>)
+            using
+            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
+            as the search path.
+            Finally, BitBake parses in order any append files found in
+            <filename>BBFILES</filename>.
+        </para>
+
+        <para>
+            One common convention is to use the recipe filename to define
+            pieces of metadata.
+            For example, in <filename>bitbake.conf</filename> the recipe
+            name and version are used to set the variables
+            <link linkend='var-PN'><filename>PN</filename></link> and
+            <link linkend='var-PV'><filename>PV</filename></link>:

+     PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"
+     PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[1] or '1.0'}"
+            </literallayout>
+            In this example, a recipe called "something_1.2.3.bb" would set
+            <filename>PN</filename> to "something" and
+            <filename>PV</filename> to "1.2.3".

+        <para>
+            By the time parsing is complete for a recipe, BitBake
+            has a list of tasks that the recipe defines and a set of
+            data consisting of keys and values as well as
+            dependency information about the tasks.
+        </para>
+
+        <para>
+            BitBake does not need all of this information.
+            It only needs a small subset of the information to make
+            decisions about the recipe.
+            Consequently, BitBake caches the values in which it is
+            interested and does not store the rest of the information.
+            Experience has shown it is faster to re-parse the metadata than to
+            try and write it out to the disk and then reload it.
+        </para>
+
+        <para>
+            Where possible, subsequent BitBake commands reuse this cache of
+            recipe information.
+            The validity of this cache is determined by first computing a
+            checksum of the base configuration data (see
+            <link linkend='var-BB_HASHCONFIG_WHITELIST'><filename>BB_HASHCONFIG_WHITELIST</filename></link>)
+            and then checking if the checksum matches.
+            If that checksum matches what is in the cache and the recipe
+            and class files have not changed, Bitbake is able to use
+            the cache.
+            BitBake then reloads the cached information about the recipe
+            instead of reparsing it from scratch.

+            custom modifications that one does not want upstream.

+                The layers mechanism is now the preferred method of collecting

+        <para>
+            Assuming BitBake has been instructed to execute a target
+            and that all the recipe files have been parsed, BitBake
+            starts to figure out how to build the target.
+            BitBake looks through the <filename>PROVIDES</filename> list
+            for each of the recipes.
+            A <filename>PROVIDES</filename> list is the list of names by which
+            the recipe can be known.
+            Each recipe's <filename>PROVIDES</filename> list is created
+            implicitly through the recipe's
+            <link linkend='var-PN'><filename>PN</filename></link> variable
+            and explicitly through the recipe's
+            <link linkend='var-PROVIDES'><filename>PROVIDES</filename></link>

+        </para>
+
+        <para>
+            When a recipe uses <filename>PROVIDES</filename>, that recipe's
+            functionality can be found under an alternative name or names other
+            than the implicit <filename>PN</filename> name.
+            As an example, suppose a recipe named <filename>keyboard_1.0.bb</filename>
+            contained the following:
+            <literallayout class='monospaced'>
+     PROVIDES += "fullkeyboard"
+            </literallayout>
+            The <filename>PROVIDES</filename> list for this recipe becomes
+            "keyboard", which is implicit, and "fullkeyboard", which is explicit.
+            Consequently, the functionality found in
+            <filename>keyboard_1.0.bb</filename> can be found under two

+            for figuring out a target's recipes.
+            Because targets might have multiple providers, BitBake needs

+

+            A common example in which a target has multiple providers
+            is "virtual/kernel", which is on the

+            Each machine often selects the best kernel provider by using a

+     PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"

+        </para>
+
+        <para>
+            Understanding how providers are chosen is made complicated by the fact
+            that multiple versions might exist for a given provider.
+            BitBake defaults to the highest version of a provider.
+            Version comparisons are made using the same method as Debian.
+            You can use the
+            <link linkend='var-PREFERRED_VERSION'><filename>PREFERRED_VERSION</filename></link>
+            variable to specify a particular version.
+            You can influence the order by using the

+            variable.
+        </para>

+            Setting <filename>DEFAULT_PREFERENCE</filename> to "1" makes it
+            likely the recipe is used.
+            <filename>PREFERRED_VERSION</filename> overrides any
+            <filename>DEFAULT_PREFERENCE</filename> setting.
+            <filename>DEFAULT_PREFERENCE</filename> is often used to mark newer

+            sufficient testing to be considered stable.
+        </para>
+
+        <para>
+            When there are multiple “versions” of a given recipe,

+            If the recipe in question has a
+            <link linkend='var-DEFAULT_PREFERENCE'><filename>DEFAULT_PREFERENCE</filename></link>
+            set lower than the other recipes (default is 0), then
+            it will not be selected.
+            This allows the person or persons maintaining
+            the repository of recipe files to specify
+            their preference for the default selected version.
+            Additionally, the user can specify their preferred version.
+        </para>
+
+        <para>
+            If the first recipe is named <filename>a_1.1.bb</filename>, then the

+            <para>
+                It is common for a recipe to provide two versions -- a stable,

+            variable.
+            BitBake continues to fork threads as long as there are tasks ready to run,

+            As each task completes, a timestamp is written to the directory specified by the

+            tasks that are already completed unless a timestamp is found to be invalid.
+            Currently, invalid timestamps are only considered on a per
+            recipe file basis.
+            So, for example, if the configure stamp has a timestamp greater than the
+            compile timestamp for a given target, then the compile task would rerun.
+            Running the compile task again, however, has no effect on other providers

+
+        <para>
+            The exact format of the stamps is partly configurable.
+            In modern versions of BitBake, a hash is appended to the
+            stamp so that if the configuration changes, the stamp becomes
+            invalid and the task is automatically rerun.
+            This hash, or signature used, is governed by the signature policy
+            that is configured (see the
+            "<link linkend='checksums'>Checksums (Signatures)</link>"
+            section for information).
+            It is also possible to append extra metadata to the stamp using

+            For example, OpenEmbedded uses this flag to make some tasks machine-specific.

+            The order in which BitBake runs the tasks is controlled by its
+            task scheduler.
+            It is possible to configure the scheduler and define custom
+            implementations for specific use cases.
+            For more information, see these variables that control the
+            behavior:

+            It is possible to have functions run before and after a task's main
+            function.
+            This is done using the <filename>[prefuncs]</filename>
+            and <filename>[postfuncs]</filename> flags of the task
+            that lists the functions to run.

+        <title>Checksums (Signatures)</title>
+
+        <para>
+            A checksum is a unique signature of a task's inputs.
+            The signature of a task can be used to determine if a task
+            needs to be run.
+            Because it is a change in a task's inputs that triggers running
+            the task, BitBake needs to detect all the inputs to a given task.
+            For shell tasks, this turns out to be fairly easy because
+            BitBake generates a "run" shell script for each task and
+            it is possible to create a checksum that gives you a good idea of when
+            the task's data changes.
+        </para>
+
+        <para>
+            To complicate the problem, some things should not be included in
+            the checksum.
+            First, there is the actual specific build path of a given task -
+            the working directory.
+            It does not matter if the working directory changes because it should not
+            affect the output for target packages.
+            The simplistic approach for excluding the working directory is to set
+            it to some fixed value and create the checksum for the "run" script.
+            BitBake goes one step better and uses the
+            <link linkend='var-BB_HASHBASE_WHITELIST'><filename>BB_HASHBASE_WHITELIST</filename></link>
+            variable to define a list of variables that should never be included
+            when generating the signatures.
+        </para>
+
+        <para>
+            Another problem results from the "run" scripts containing functions that
+            might or might not get called.
+            The incremental build solution contains code that figures out dependencies
+            between shell functions.
+            This code is used to prune the "run" scripts down to the minimum set,
+            thereby alleviating this problem and making the "run" scripts much more
+            readable as a bonus.
+        </para>
+
+        <para>
+            So far we have solutions for shell scripts.
+            What about Python tasks?
+            The same approach applies even though these tasks are more difficult.
+            The process needs to figure out what variables a Python function accesses
+            and what functions it calls.
+            Again, the incremental build solution contains code that first figures out
+            the variable and function dependencies, and then creates a checksum for the data
+            used as the input to the task.
+        </para>
+
+        <para>
+            Like the working directory case, situations exist where dependencies
+            should be ignored.
+            For these cases, you can instruct the build process to ignore a dependency
+            by using a line like the following:
+            <literallayout class='monospaced'>
+     PACKAGE_ARCHS[vardepsexclude] = "MACHINE"
+            </literallayout>
+            This example ensures that the <filename>PACKAGE_ARCHS</filename> variable does not
+            depend on the value of <filename>MACHINE</filename>, even if it does reference it.
+        </para>
+
+        <para>
+            Equally, there are cases where we need to add dependencies BitBake
+            is not able to find.
+            You can accomplish this by using a line like the following:
+            <literallayout class='monospaced'>
+      PACKAGE_ARCHS[vardeps] = "MACHINE"
+            </literallayout>
+            This example explicitly adds the <filename>MACHINE</filename> variable as a
+            dependency for <filename>PACKAGE_ARCHS</filename>.
+        </para>
+
+        <para>
+            Consider a case with in-line Python, for example, where BitBake is not
+            able to figure out dependencies.
+            When running in debug mode (i.e. using <filename>-DDD</filename>), BitBake
+            produces output when it discovers something for which it cannot figure out
+            dependencies.
+        </para>
+
+        <para>
+            Thus far, this section has limited discussion to the direct inputs into a task.
+            Information based on direct inputs is referred to as the "basehash" in the
+            code.
+            However, there is still the question of a task's indirect inputs - the
+            things that were already built and present in the build directory.
+            The checksum (or signature) for a particular task needs to add the hashes
+            of all the tasks on which the particular task depends.
+            Choosing which dependencies to add is a policy decision.
+            However, the effect is to generate a master checksum that combines the basehash
+            and the hashes of the task's dependencies.
+        </para>
+
+        <para>
+            At the code level, there are a variety of ways both the basehash and the
+            dependent task hashes can be influenced.
+            Within the BitBake configuration file, we can give BitBake some extra information
+            to help it construct the basehash.
+            The following statement effectively results in a list of global variable
+            dependency excludes - variables never included in any checksum.
+            This example uses variables from OpenEmbedded to help illustrate
+            the concept:
+            <literallayout class='monospaced'>
+     BB_HASHBASE_WHITELIST ?= "TMPDIR FILE PATH PWD BB_TASKHASH BBPATH DL_DIR \
+         SSTATE_DIR THISDIR FILESEXTRAPATHS FILE_DIRNAME HOME LOGNAME SHELL TERM \
+         USER FILESPATH STAGING_DIR_HOST STAGING_DIR_TARGET COREBASE PRSERV_HOST \
+         PRSERV_DUMPDIR PRSERV_DUMPFILE PRSERV_LOCKDOWN PARALLEL_MAKE \
+         CCACHE_DIR EXTERNAL_TOOLCHAIN CCACHE CCACHE_DISABLE LICENSE_PATH SDKPKGSUFFIX"
+            </literallayout>
+            The previous example excludes the work directory, which is part of
+            <filename>TMPDIR</filename>.
+        </para>
+
+        <para>
+            The rules for deciding which hashes of dependent tasks to include through
+            dependency chains are more complex and are generally accomplished with a
+            Python function.
+            The code in <filename>meta/lib/oe/sstatesig.py</filename> shows two examples
+            of this and also illustrates how you can insert your own policy into the system
+            if so desired.
+            This file defines the two basic signature generators OpenEmbedded Core
+            uses:  "OEBasic" and "OEBasicHash".
+            By default, there is a dummy "noop" signature handler enabled in BitBake.
+            This means that behavior is unchanged from previous versions.
+            <filename>OE-Core</filename> uses the "OEBasicHash" signature handler by default
+            through this setting in the <filename>bitbake.conf</filename> file:
+            <literallayout class='monospaced'>
+     BB_SIGNATURE_HANDLER ?= "OEBasicHash"
+            </literallayout>
+            The "OEBasicHash" <filename>BB_SIGNATURE_HANDLER</filename> is the same as the
+            "OEBasic" version but adds the task hash to the stamp files.
+            This results in any metadata change that changes the task hash, automatically
+            causing the task to be run again.
+            This removes the need to bump
+            <link linkend='var-PR'><filename>PR</filename></link>
+            values, and changes to metadata automatically ripple across the build.
+        </para>
+
+        <para>
+            It is also worth noting that the end result of these signature generators is to
+            make some dependency and hash information available to the build.
+            This information includes:

+
+        <para>
+            It is worth noting that BitBake's "-S" option lets you
+            debug Bitbake's processing of signatures.
+            The options passed to -S allow different debugging modes
+            to be used, either using BitBake's own debug functions
+            or possibly those defined in the metadata/signature handler
+            itself.
+            The simplest parameter to pass is "none", which causes a
+            set of signature information to be written out into
+            <filename>STAMPS_DIR</filename>
+            corresponding to the targets specified.
+            The other currently available parameter is "printdiff",
+            which causes BitBake to try to establish the closest
+            signature match it can (e.g. in the sstate cache) and then
+            run <filename>bitbake-diffsigs</filename> over the matches
+            to determine the stamps and delta where these two
+            stamp trees diverge.
+            <note>
+                It is likely that future versions of BitBake will
+                provide other signature handlers triggered through
+                additional "-S" parameters.

+            The setscene process enables BitBake to handle "pre-built" artifacts.
+            The ability to handle and reuse these artifacts allows BitBake
+            the luxury of not having to build something from scratch every time.

+            BitBake needs to have reliable data indicating whether or not an

+            way of representing whether an artifact is compatible.

+        </para>
+
+        <para>
+            If an object can be reused, the problem then becomes how to

+            BitBake solves the problem with the "setscene" process.
+        </para>
+
+        <para>
+            When BitBake is asked to build a given target, before building anything,
+            it first asks whether cached information is available for any of the
+            targets it's building, or any of the intermediate targets.
+            If cached information is available, BitBake uses this information instead of
+            running the main tasks.
+        </para>
+
+        <para>
+            BitBake first calls the function defined by the
+            <link linkend='var-BB_HASHCHECK_FUNCTION'><filename>BB_HASHCHECK_FUNCTION</filename></link>
+            variable with a list of tasks and corresponding
+            hashes it wants to build.
+            This function is designed to be fast and returns a list

+        </para>
+
+        <para>
+            Next, for each of the tasks that were returned as possibilities,
+            BitBake executes a setscene version of the task that the possible
+            artifact covers.
+            Setscene versions of a task have the string "_setscene" appended to the
+            task name.
+            So, for example, the task with the name <filename>xxx</filename> has
+            a setscene task named <filename>xxx_setscene</filename>.
+            The setscene version of the task executes and provides the necessary

+        </para>
+
+        <para>
+            As previously mentioned, an artifact can cover more than one task.
+            For example, it is pointless to obtain a compiler if you
+            already have the compiled binary.
+            To handle this, BitBake calls the
+            <link linkend='var-BB_SETSCENE_DEPVALID'><filename>BB_SETSCENE_DEPVALID</filename></link>
+            function for each successful setscene task to know whether or not it needs

+        </para>
+
+        <para>
+            Finally, after all the setscene tasks have executed, BitBake calls the

+            with the list of tasks BitBake thinks has been "covered".
+            The metadata can then ensure that this list is correct and can

-=====================
-File Download Support
-=====================

-
-BitBake's fetch module is a standalone piece of library code that deals
-with the intricacies of downloading source code and files from remote
-systems. Fetching source code is one of the cornerstones of building
-software. As such, this module forms an important part of BitBake.
-
-The current fetch module is called "fetch2" and refers to the fact that
-it is the second major version of the API. The original version is
-obsolete and has been removed from the codebase. Thus, in all cases,
-"fetch" refers to "fetch2" in this manual.
-
-The Download (Fetch)
-====================
-
-BitBake takes several steps when fetching source code or files. The
-fetcher codebase deals with two distinct processes in order: obtaining
-the files from somewhere (cached or otherwise) and then unpacking those
-files into a specific location and perhaps in a specific way. Getting
-and unpacking the files is often optionally followed by patching.
-Patching, however, is not covered by this module.
-
-The code to execute the first part of this process, a fetch, looks
-something like the following::
-
-   src_uri = (d.getVar('SRC_URI') or "").split()
-   fetcher = bb.fetch2.Fetch(src_uri, d)
-   fetcher.download()
-
-This code sets up an instance of the fetch class. The instance uses a
-space-separated list of URLs from the :term:`SRC_URI`
-variable and then calls the ``download`` method to download the files.
-
-The instantiation of the fetch class is usually followed by::
-
-   rootdir = l.getVar('WORKDIR')
-   fetcher.unpack(rootdir)
-
-This code unpacks the downloaded files to the specified by ``WORKDIR``.
-
-.. note::
-
-   For convenience, the naming in these examples matches the variables
-   used by OpenEmbedded. If you want to see the above code in action,
-   examine the OpenEmbedded class file ``base.bbclass``
-   .
-
-The :term:`SRC_URI` and ``WORKDIR`` variables are not hardcoded into the
-fetcher, since those fetcher methods can be (and are) called with
-different variable names. In OpenEmbedded for example, the shared state
-(sstate) code uses the fetch module to fetch the sstate files.
-
-When the ``download()`` method is called, BitBake tries to resolve the
-URLs by looking for source files in a specific search order:
-
--  *Pre-mirror Sites:* BitBake first uses pre-mirrors to try and find
-   source files. These locations are defined using the
-   :term:`PREMIRRORS` variable.
-
--  *Source URI:* If pre-mirrors fail, BitBake uses the original URL (e.g
-   from :term:`SRC_URI`).
-
--  *Mirror Sites:* If fetch failures occur, BitBake next uses mirror
-   locations as defined by the :term:`MIRRORS` variable.
-
-For each URL passed to the fetcher, the fetcher calls the submodule that
-handles that particular URL type. This behavior can be the source of
-some confusion when you are providing URLs for the :term:`SRC_URI` variable.
-Consider the following two URLs::
-
-   https://git.yoctoproject.org/git/poky;protocol=git
-   git://git.yoctoproject.org/git/poky;protocol=http
-
-In the former case, the URL is passed to the ``wget`` fetcher, which does not
-understand "git". Therefore, the latter case is the correct form since the Git
-fetcher does know how to use HTTP as a transport.
-
-Here are some examples that show commonly used mirror definitions::
-
-   PREMIRRORS ?= "\
-      bzr://.*/.\*  http://somemirror.org/sources/ \
-      cvs://.*/.\*  http://somemirror.org/sources/ \
-      git://.*/.\*  http://somemirror.org/sources/ \
-      hg://.*/.\*   http://somemirror.org/sources/ \
-      osc://.*/.\*  http://somemirror.org/sources/ \
-      p4://.*/.\*   http://somemirror.org/sources/ \
-     svn://.*/.\*   http://somemirror.org/sources/"
-
-   MIRRORS =+ "\
-      ftp://.*/.\*   http://somemirror.org/sources/ \
-      http://.*/.\*  http://somemirror.org/sources/ \
-      https://.*/.\* http://somemirror.org/sources/"
-
-It is useful to note that BitBake
-supports cross-URLs. It is possible to mirror a Git repository on an
-HTTP server as a tarball. This is what the ``git://`` mapping in the
-previous example does.
-
-Since network accesses are slow, BitBake maintains a cache of files
-downloaded from the network. Any source files that are not local (i.e.
-downloaded from the Internet) are placed into the download directory,
-which is specified by the :term:`DL_DIR` variable.
-
-File integrity is of key importance for reproducing builds. For
-non-local archive downloads, the fetcher code can verify SHA-256 and MD5
-checksums to ensure the archives have been downloaded correctly. You can
-specify these checksums by using the :term:`SRC_URI` variable with the
-appropriate varflags as follows::
-
-   SRC_URI[md5sum] = "value"
-   SRC_URI[sha256sum] = "value"
-
-You can also specify the checksums as
-parameters on the :term:`SRC_URI` as shown below::
-
-  SRC_URI = "http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d"
-
-If multiple URIs exist, you can specify the checksums either directly as
-in the previous example, or you can name the URLs. The following syntax
-shows how you name the URIs::
-
-   SRC_URI = "http://example.com/foobar.tar.bz2;name=foo"
-   SRC_URI[foo.md5sum] = 4a8e0f237e961fd7785d19d07fdb994d
-
-After a file has been downloaded and
-has had its checksum checked, a ".done" stamp is placed in :term:`DL_DIR`.
-BitBake uses this stamp during subsequent builds to avoid downloading or
-comparing a checksum for the file again.
-
-.. note::
-
-   It is assumed that local storage is safe from data corruption. If
-   this were not the case, there would be bigger issues to worry about.
-
-If :term:`BB_STRICT_CHECKSUM` is set, any
-download without a checksum triggers an error message. The
-:term:`BB_NO_NETWORK` variable can be used to
-make any attempted network access a fatal error, which is useful for
-checking that mirrors are complete as well as other things.
-
-If :term:`BB_CHECK_SSL_CERTS` is set to ``0`` then SSL certificate checking will
-be disabled. This variable defaults to ``1`` so SSL certificates are normally
-checked.
-
-.. _bb-the-unpack:
-
-The Unpack
-==========
-
-The unpack process usually immediately follows the download. For all
-URLs except Git URLs, BitBake uses the common ``unpack`` method.
-
-A number of parameters exist that you can specify within the URL to
-govern the behavior of the unpack stage:
-
--  *unpack:* Controls whether the URL components are unpacked. If set to
-   "1", which is the default, the components are unpacked. If set to
-   "0", the unpack stage leaves the file alone. This parameter is useful
-   when you want an archive to be copied in and not be unpacked.
-
--  *dos:* Applies to ``.zip`` and ``.jar`` files and specifies whether
-   to use DOS line ending conversion on text files.
-
--  *striplevel:* Strip specified number of leading components (levels)
-   from file names on extraction
-
--  *subdir:* Unpacks the specific URL to the specified subdirectory
-   within the root directory.
-
-The unpack call automatically decompresses and extracts files with ".Z",
-".z", ".gz", ".xz", ".zip", ".jar", ".ipk", ".rpm". ".srpm", ".deb" and
-".bz2" extensions as well as various combinations of tarball extensions.
-
-As mentioned, the Git fetcher has its own unpack method that is
-optimized to work with Git trees. Basically, this method works by
-cloning the tree into the final directory. The process is completed
-using references so that there is only one central copy of the Git
-metadata needed.
-
-.. _bb-fetchers:
-
-Fetchers
-========
-
-As mentioned earlier, the URL prefix determines which fetcher submodule
-BitBake uses. Each submodule can support different URL parameters, which
-are described in the following sections.
-
-.. _local-file-fetcher:
-
-Local file fetcher (``file://``)
---------------------------------
-
-This submodule handles URLs that begin with ``file://``. The filename
-you specify within the URL can be either an absolute or relative path to
-a file. If the filename is relative, the contents of the
-:term:`FILESPATH` variable is used in the same way
-``PATH`` is used to find executables. If the file cannot be found, it is
-assumed that it is available in :term:`DL_DIR` by the
-time the ``download()`` method is called.
-
-If you specify a directory, the entire directory is unpacked.
-
-Here are a couple of example URLs, the first relative and the second
-absolute::
-
-   SRC_URI = "file://relativefile.patch"
-   SRC_URI = "file:///Users/ich/very_important_software"
-
-.. _http-ftp-fetcher:
-
-HTTP/FTP wget fetcher (``http://``, ``ftp://``, ``https://``)
--------------------------------------------------------------
-
-This fetcher obtains files from web and FTP servers. Internally, the
-fetcher uses the wget utility.
-
-The executable and parameters used are specified by the
-``FETCHCMD_wget`` variable, which defaults to sensible values. The
-fetcher supports a parameter "downloadfilename" that allows the name of
-the downloaded file to be specified. Specifying the name of the
-downloaded file is useful for avoiding collisions in
-:term:`DL_DIR` when dealing with multiple files that
-have the same name.
-
-If a username and password are specified in the ``SRC_URI``, a Basic
-Authorization header will be added to each request, including across redirects.
-To instead limit the Authorization header to the first request, add
-"redirectauth=0" to the list of parameters.
-
-Some example URLs are as follows::
-
-   SRC_URI = "http://oe.handhelds.org/not_there.aac"
-   SRC_URI = "ftp://oe.handhelds.org/not_there_as_well.aac"
-   SRC_URI = "ftp://you@oe.handhelds.org/home/you/secret.plan"
-
-.. note::
-
-   Because URL parameters are delimited by semi-colons, this can
-   introduce ambiguity when parsing URLs that also contain semi-colons,
-   for example::
-
-           SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git;a=snapshot;h=a5dd47"
-
-
-   Such URLs should should be modified by replacing semi-colons with '&'
-   characters::
-
-           SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&a=snapshot&h=a5dd47"
-
-
-   In most cases this should work. Treating semi-colons and '&' in
-   queries identically is recommended by the World Wide Web Consortium
-   (W3C). Note that due to the nature of the URL, you may have to
-   specify the name of the downloaded file as well::
-
-           SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&a=snapshot&h=a5dd47;downloadfilename=myfile.bz2"
-
-
-.. _cvs-fetcher:
-
-CVS fetcher (``(cvs://``)
--------------------------
-
-This submodule handles checking out files from the CVS version control
-system. You can configure it using a number of different variables:
-
--  :term:`FETCHCMD_cvs <FETCHCMD>`: The name of the executable to use when running
-   the ``cvs`` command. This name is usually "cvs".
-
--  :term:`SRCDATE`: The date to use when fetching the CVS source code. A
-   special value of "now" causes the checkout to be updated on every
-   build.
-
--  :term:`CVSDIR`: Specifies where a temporary
-   checkout is saved. The location is often ``DL_DIR/cvs``.
-
--  CVS_PROXY_HOST: The name to use as a "proxy=" parameter to the
-   ``cvs`` command.
-
--  CVS_PROXY_PORT: The port number to use as a "proxyport="
-   parameter to the ``cvs`` command.
-
-As well as the standard username and password URL syntax, you can also
-configure the fetcher with various URL parameters:
-
-The supported parameters are as follows:
-
--  *"method":* The protocol over which to communicate with the CVS
-   server. By default, this protocol is "pserver". If "method" is set to
-   "ext", BitBake examines the "rsh" parameter and sets ``CVS_RSH``. You
-   can use "dir" for local directories.
-
--  *"module":* Specifies the module to check out. You must supply this
-   parameter.
-
--  *"tag":* Describes which CVS TAG should be used for the checkout. By
-   default, the TAG is empty.
-
--  *"date":* Specifies a date. If no "date" is specified, the
-   :term:`SRCDATE` of the configuration is used to
-   checkout a specific date. The special value of "now" causes the
-   checkout to be updated on every build.
-
--  *"localdir":* Used to rename the module. Effectively, you are
-   renaming the output directory to which the module is unpacked. You
-   are forcing the module into a special directory relative to
-   :term:`CVSDIR`.
-
--  *"rsh":* Used in conjunction with the "method" parameter.
-
--  *"scmdata":* Causes the CVS metadata to be maintained in the tarball
-   the fetcher creates when set to "keep". The tarball is expanded into
-   the work directory. By default, the CVS metadata is removed.
-
--  *"fullpath":* Controls whether the resulting checkout is at the
-   module level, which is the default, or is at deeper paths.
-
--  *"norecurse":* Causes the fetcher to only checkout the specified
-   directory with no recurse into any subdirectories.
-
--  *"port":* The port to which the CVS server connects.
-
-Some example URLs are as follows::
-
-   SRC_URI = "cvs://CVSROOT;module=mymodule;tag=some-version;method=ext"
-   SRC_URI = "cvs://CVSROOT;module=mymodule;date=20060126;localdir=usethat"
-
-.. _svn-fetcher:
-
-Subversion (SVN) Fetcher (``svn://``)
--------------------------------------
-
-This fetcher submodule fetches code from the Subversion source control
-system. The executable used is specified by ``FETCHCMD_svn``, which
-defaults to "svn". The fetcher's temporary working directory is set by
-:term:`SVNDIR`, which is usually ``DL_DIR/svn``.
-
-The supported parameters are as follows:
-
--  *"module":* The name of the svn module to checkout. You must provide
-   this parameter. You can think of this parameter as the top-level
-   directory of the repository data you want.
-
--  *"path_spec":* A specific directory in which to checkout the
-   specified svn module.
-
--  *"protocol":* The protocol to use, which defaults to "svn". If
-   "protocol" is set to "svn+ssh", the "ssh" parameter is also used.
-
--  *"rev":* The revision of the source code to checkout.
-
--  *"scmdata":* Causes the ".svn" directories to be available during
-   compile-time when set to "keep". By default, these directories are
-   removed.
-
--  *"ssh":* An optional parameter used when "protocol" is set to
-   "svn+ssh". You can use this parameter to specify the ssh program used
-   by svn.
-
--  *"transportuser":* When required, sets the username for the
-   transport. By default, this parameter is empty. The transport
-   username is different than the username used in the main URL, which
-   is passed to the subversion command.
-
-Following are three examples using svn::
-
-   SRC_URI = "svn://myrepos/proj1;module=vip;protocol=http;rev=667"
-   SRC_URI = "svn://myrepos/proj1;module=opie;protocol=svn+ssh"
-   SRC_URI = "svn://myrepos/proj1;module=trunk;protocol=http;path_spec=${MY_DIR}/proj1"
-
-.. _git-fetcher:
-
-Git Fetcher (``git://``)
-------------------------
-
-This fetcher submodule fetches code from the Git source control system.
-The fetcher works by creating a bare clone of the remote into
-:term:`GITDIR`, which is usually ``DL_DIR/git2``. This
-bare clone is then cloned into the work directory during the unpack
-stage when a specific tree is checked out. This is done using alternates
-and by reference to minimize the amount of duplicate data on the disk
-and make the unpack process fast. The executable used can be set with
-``FETCHCMD_git``.
-
-This fetcher supports the following parameters:
-
--  *"protocol":* The protocol used to fetch the files. The default is
-   "git" when a hostname is set. If a hostname is not set, the Git
-   protocol is "file". You can also use "http", "https", "ssh" and
-   "rsync".
-
-   .. note::
-
-     When ``protocol`` is "ssh", the URL expected in :term:`SRC_URI` differs
-     from the one that is typically passed to ``git clone`` command and provided
-     by the Git server to fetch from. For example, the URL returned by GitLab
-     server for ``mesa`` when cloning over SSH is
-     ``git@gitlab.freedesktop.org:mesa/mesa.git``, however the expected URL in
-     :term:`SRC_URI` is the following::
-
-       SRC_URI = "git://git@gitlab.freedesktop.org/mesa/mesa.git;branch=main;protocol=ssh;..."
-
-     Note the ``:`` character changed for a ``/`` before the path to the project.
-
--  *"nocheckout":* Tells the fetcher to not checkout source code when
-   unpacking when set to "1". Set this option for the URL where there is
-   a custom routine to checkout code. The default is "0".
-
--  *"rebaseable":* Indicates that the upstream Git repository can be
-   rebased. You should set this parameter to "1" if revisions can become
-   detached from branches. In this case, the source mirror tarball is
-   done per revision, which has a loss of efficiency. Rebasing the
-   upstream Git repository could cause the current revision to disappear
-   from the upstream repository. This option reminds the fetcher to
-   preserve the local cache carefully for future use. The default value
-   for this parameter is "0".
-
--  *"nobranch":* Tells the fetcher to not check the SHA validation for
-   the branch when set to "1". The default is "0". Set this option for
-   the recipe that refers to the commit that is valid for any namespace
-   (branch, tag, ...) instead of the branch.
-
--  *"bareclone":* Tells the fetcher to clone a bare clone into the
-   destination directory without checking out a working tree. Only the
-   raw Git metadata is provided. This parameter implies the "nocheckout"
-   parameter as well.
-
--  *"branch":* The branch(es) of the Git tree to clone. Unless
-   "nobranch" is set to "1", this is a mandatory parameter. The number of
-   branch parameters must match the number of name parameters.
-
--  *"rev":* The revision to use for the checkout. The default is
-   "master".
-
--  *"tag":* Specifies a tag to use for the checkout. To correctly
-   resolve tags, BitBake must access the network. For that reason, tags
-   are often not used. As far as Git is concerned, the "tag" parameter
-   behaves effectively the same as the "rev" parameter.
-
--  *"subpath":* Limits the checkout to a specific subpath of the tree.
-   By default, the whole tree is checked out.
-
--  *"destsuffix":* The name of the path in which to place the checkout.
-   By default, the path is ``git/``.
-
--  *"usehead":* Enables local ``git://`` URLs to use the current branch
-   HEAD as the revision for use with ``AUTOREV``. The "usehead"
-   parameter implies no branch and only works when the transfer protocol
-   is ``file://``.
-
-Here are some example URLs::
-
-   SRC_URI = "git://github.com/fronteed/icheck.git;protocol=https;branch=${PV};tag=${PV}"
-   SRC_URI = "git://github.com/asciidoc/asciidoc-py;protocol=https;branch=main"
-   SRC_URI = "git://git@gitlab.freedesktop.org/mesa/mesa.git;branch=main;protocol=ssh;..."
-
-.. note::
-
-   When using ``git`` as the fetcher of the main source code of your software,
-   ``S`` should be set accordingly::
-
-       S = "${WORKDIR}/git"
-
-.. note::
-
-   Specifying passwords directly in ``git://`` urls is not supported.
-   There are several reasons: :term:`SRC_URI` is often written out to logs and
-   other places, and that could easily leak passwords; it is also all too
-   easy to share metadata without removing passwords. SSH keys, ``~/.netrc``
-   and ``~/.ssh/config`` files can be used as alternatives.
-
-Using tags with the git fetcher may cause surprising behaviour. Bitbake needs to
-resolve the tag to a specific revision and to do that, it has to connect to and use
-the upstream repository. This is because the revision the tags point at can change and
-we've seen cases of this happening in well known public repositories. This can mean
-many more network connections than expected and recipes may be reparsed at every build.
-Source mirrors will also be bypassed as the upstream repository is the only source
-of truth to resolve the revision accurately. For these reasons, whilst the fetcher
-can support tags, we recommend being specific about revisions in recipes.
-
-.. _gitsm-fetcher:
-
-Git Submodule Fetcher (``gitsm://``)
-------------------------------------
-
-This fetcher submodule inherits from the :ref:`Git
-fetcher<bitbake-user-manual/bitbake-user-manual-fetching:git fetcher
-(\`\`git://\`\`)>` and extends that fetcher's behavior by fetching a
-repository's submodules. :term:`SRC_URI` is passed to the Git fetcher as
-described in the :ref:`bitbake-user-manual/bitbake-user-manual-fetching:git
-fetcher (\`\`git://\`\`)` section.
-
-.. note::
-
-   You must clean a recipe when switching between '``git://``' and
-   '``gitsm://``' URLs.
-
-   The Git Submodules fetcher is not a complete fetcher implementation.
-   The fetcher has known issues where it does not use the normal source
-   mirroring infrastructure properly. Further, the submodule sources it
-   fetches are not visible to the licensing and source archiving
-   infrastructures.
-
-.. _clearcase-fetcher:
-
-ClearCase Fetcher (``ccrc://``)
--------------------------------
-
-This fetcher submodule fetches code from a
-`ClearCase <http://en.wikipedia.org/wiki/Rational_ClearCase>`__
-repository.
-
-To use this fetcher, make sure your recipe has proper
-:term:`SRC_URI`, :term:`SRCREV`, and
-:term:`PV` settings. Here is an example::
-
-   SRC_URI = "ccrc://cc.example.org/ccrc;vob=/example_vob;module=/example_module"
-   SRCREV = "EXAMPLE_CLEARCASE_TAG"
-   PV = "${@d.getVar("SRCREV", False).replace("/", "+")}"
-
-The fetcher uses the ``rcleartool`` or
-``cleartool`` remote client, depending on which one is available.
-
-Following are options for the :term:`SRC_URI` statement:
-
--  *vob*: The name, which must include the prepending "/" character,
-   of the ClearCase VOB. This option is required.
-
--  *module*: The module, which must include the prepending "/"
-   character, in the selected VOB.
-
-   .. note::
-
-      The module and vob options are combined to create the load rule in the
-      view config spec. As an example, consider the vob and module values from
-      the SRC_URI statement at the start of this section. Combining those values
-      results in the following::
-
-         load /example_vob/example_module
-
--  *proto*: The protocol, which can be either ``http`` or ``https``.
-
-By default, the fetcher creates a configuration specification. If you
-want this specification written to an area other than the default, use
-the ``CCASE_CUSTOM_CONFIG_SPEC`` variable in your recipe to define where
-the specification is written.
-
-.. note::
-
-   the SRCREV loses its functionality if you specify this variable. However,
-   SRCREV is still used to label the archive after a fetch even though it does
-   not define what is fetched.
-
-Here are a couple of other behaviors worth mentioning:
-
--  When using ``cleartool``, the login of ``cleartool`` is handled by
-   the system. The login require no special steps.
-
--  In order to use ``rcleartool`` with authenticated users, an
-   "rcleartool login" is necessary before using the fetcher.
-
-.. _perforce-fetcher:
-
-Perforce Fetcher (``p4://``)
-----------------------------
-
-This fetcher submodule fetches code from the
-`Perforce <https://www.perforce.com/>`__ source control system. The
-executable used is specified by ``FETCHCMD_p4``, which defaults to "p4".
-The fetcher's temporary working directory is set by
-:term:`P4DIR`, which defaults to "DL_DIR/p4".
-The fetcher does not make use of a perforce client, instead it
-relies on ``p4 files`` to retrieve a list of
-files and ``p4 print`` to transfer the content
-of those files locally.
-
-To use this fetcher, make sure your recipe has proper
-:term:`SRC_URI`, :term:`SRCREV`, and
-:term:`PV` values. The p4 executable is able to use the
-config file defined by your system's ``P4CONFIG`` environment variable
-in order to define the Perforce server URL and port, username, and
-password if you do not wish to keep those values in a recipe itself. If
-you choose not to use ``P4CONFIG``, or to explicitly set variables that
-``P4CONFIG`` can contain, you can specify the ``P4PORT`` value, which is
-the server's URL and port number, and you can specify a username and
-password directly in your recipe within :term:`SRC_URI`.
-
-Here is an example that relies on ``P4CONFIG`` to specify the server URL
-and port, username, and password, and fetches the Head Revision::
-
-   SRC_URI = "p4://example-depot/main/source/..."
-   SRCREV = "${AUTOREV}"
-   PV = "p4-${SRCPV}"
-   S = "${WORKDIR}/p4"
-
-Here is an example that specifies the server URL and port, username, and
-password, and fetches a Revision based on a Label::
-
-   P4PORT = "tcp:p4server.example.net:1666"
-   SRC_URI = "p4://user:passwd@example-depot/main/source/..."
-   SRCREV = "release-1.0"
-   PV = "p4-${SRCPV}"
-   S = "${WORKDIR}/p4"
-
-.. note::
-
-   You should always set S to "${WORKDIR}/p4" in your recipe.
-
-By default, the fetcher strips the depot location from the local file paths. In
-the above example, the content of ``example-depot/main/source/`` will be placed
-in ``${WORKDIR}/p4``.  For situations where preserving parts of the remote depot
-paths locally is desirable, the fetcher supports two parameters:
-
-- *"module":*
-    The top-level depot location or directory to fetch. The value of this
-    parameter can also point to a single file within the depot, in which case
-    the local file path will include the module path.
-- *"remotepath":*
-    When used with the value "``keep``", the fetcher will mirror the full depot
-    paths locally for the specified location, even in combination with the
-    ``module`` parameter.
-
-Here is an example use of the the ``module`` parameter::
-
-   SRC_URI = "p4://user:passwd@example-depot/main;module=source/..."
-
-In this case, the content of the top-level directory ``source/`` will be fetched
-to ``${P4DIR}``, including the directory itself.  The top-level directory will
-be accesible at ``${P4DIR}/source/``.
-
-Here is an example use of the the ``remotepath`` parameter::
-
-   SRC_URI = "p4://user:passwd@example-depot/main;module=source/...;remotepath=keep"
-
-In this case, the content of the top-level directory ``source/`` will be fetched
-to ``${P4DIR}``, but the complete depot paths will be mirrored locally. The
-top-level directory will be accessible at
-``${P4DIR}/example-depot/main/source/``.
-
-.. _repo-fetcher:
-
-Repo Fetcher (``repo://``)
---------------------------
-
-This fetcher submodule fetches code from ``google-repo`` source control
-system. The fetcher works by initiating and syncing sources of the
-repository into :term:`REPODIR`, which is usually
-``${DL_DIR}/repo``.
-
-This fetcher supports the following parameters:
-
--  *"protocol":* Protocol to fetch the repository manifest (default:
-   git).
-
--  *"branch":* Branch or tag of repository to get (default: master).
-
--  *"manifest":* Name of the manifest file (default: ``default.xml``).
-
-Here are some example URLs::
-
-   SRC_URI = "repo://REPOROOT;protocol=git;branch=some_branch;manifest=my_manifest.xml"
-   SRC_URI = "repo://REPOROOT;protocol=file;branch=some_branch;manifest=my_manifest.xml"
-
-.. _az-fetcher:
-
-Az Fetcher (``az://``)
---------------------------
-
-This submodule fetches data from an
-`Azure Storage account <https://docs.microsoft.com/en-us/azure/storage/>`__ ,
-it inherits its functionality from the HTTP wget fetcher, but modifies its
-behavior to accomodate the usage of a
-`Shared Access Signature (SAS) <https://docs.microsoft.com/en-us/azure/storage/common/storage-sas-overview>`__
-for non-public data.
-
-Such functionality is set by the variable:
-
--  :term:`AZ_SAS`: The Azure Storage Shared Access Signature provides secure
-   delegate access to resources, if this variable is set, the Az Fetcher will
-   use it when fetching artifacts from the cloud.
-
-You can specify the AZ_SAS variable as shown below::
-
-   AZ_SAS = "se=2021-01-01&sp=r&sv=2018-11-09&sr=c&skoid=<skoid>&sig=<signature>"
-
-Here is an example URL::
-
-   SRC_URI = "az://<azure-storage-account>.blob.core.windows.net/<foo_container>/<bar_file>"
-
-It can also be used when setting mirrors definitions using the :term:`PREMIRRORS` variable.
-
-.. _gcp-fetcher:
-
-GCP Fetcher (``gs://``)
---------------------------
-
-This submodule fetches data from a
-`Google Cloud Storage Bucket <https://cloud.google.com/storage/docs/buckets>`__.
-It uses the `Google Cloud Storage Python Client <https://cloud.google.com/python/docs/reference/storage/latest>`__
-to check the status of objects in the bucket and download them.
-The use of the Python client makes it substantially faster than using command
-line tools such as gsutil.
-
-The fetcher requires the Google Cloud Storage Python Client to be installed, along
-with the gsutil tool.
-
-The fetcher requires that the machine has valid credentials for accessing the
-chosen bucket. Instructions for authentication can be found in the
-`Google Cloud documentation <https://cloud.google.com/docs/authentication/provide-credentials-adc#local-dev>`__.
-
-If it used from the OpenEmbedded build system, the fetcher can be used for
-fetching sstate artifacts from a GCS bucket by specifying the
-``SSTATE_MIRRORS`` variable as shown below::
-
-   SSTATE_MIRRORS ?= "\
-       file://.* gs://<bucket name>/PATH \
-   "
-
-The fetcher can also be used in recipes::
-
-   SRC_URI = "gs://<bucket name>/<foo_container>/<bar_file>"
-
-However, the checksum of the file should be also be provided::
-
-   SRC_URI[sha256sum] = "<sha256 string>"
-
-.. _crate-fetcher:
-
-Crate Fetcher (``crate://``)
-----------------------------
-
-This submodule fetches code for
-`Rust language "crates" <https://doc.rust-lang.org/reference/glossary.html?highlight=crate#crate>`__
-corresponding to Rust libraries and programs to compile. Such crates are typically shared
-on https://crates.io/ but this fetcher supports other crate registries too.
-
-The format for the :term:`SRC_URI` setting must be::
-
-   SRC_URI = "crate://REGISTRY/NAME/VERSION"
-
-Here is an example URL::
-
-   SRC_URI = "crate://crates.io/glob/0.2.11"
-
-.. _npm-fetcher:
-
-NPM Fetcher (``npm://``)
-------------------------
-
-This submodule fetches source code from an
-`NPM <https://en.wikipedia.org/wiki/Npm_(software)>`__
-Javascript package registry.

+
+    <para>
+        BitBake's fetch module is a standalone piece of library code
+        that deals with the intricacies of downloading source code
+        and files from remote systems.
+        Fetching source code is one of the cornerstones of building software.
+        As such, this module forms an important part of BitBake.
+    </para>
+
+    <para>
+        The current fetch module is called "fetch2" and refers to the
+        fact that it is the second major version of the API.
+        The original version is obsolete and has been removed from the codebase.
+        Thus, in all cases, "fetch" refers to "fetch2" in this
+        manual.
+    </para>
+
+    <section id='the-download-fetch'>
+        <title>The Download (Fetch)</title>
+
+        <para>
+            BitBake takes several steps when fetching source code or files.
+            The fetcher codebase deals with two distinct processes in order:
+            obtaining the files from somewhere (cached or otherwise)
+            and then unpacking those files into a specific location and
+            perhaps in a specific way.
+            Getting and unpacking the files is often optionally followed
+            by patching.
+            Patching, however, is not covered by this module.
+        </para>
+
+        <para>
+            The code to execute the first part of this process, a fetch,
+            looks something like the following:
+            <literallayout class='monospaced'>
+     src_uri = (d.getVar('SRC_URI', True) or "").split()
+     fetcher = bb.fetch2.Fetch(src_uri, d)
+     fetcher.download()
+            </literallayout>
+            This code sets up an instance of the fetch class.
+            The instance uses a space-separated list of URLs from the
+            <link linkend='var-SRC_URI'><filename>SRC_URI</filename></link>
+            variable and then calls the <filename>download</filename>
+            method to download the files.
+        </para>
+
+        <para>
+            The instantiation of the fetch class is usually followed by:
+            <literallayout class='monospaced'>
+     rootdir = l.getVar('WORKDIR', True)
+     fetcher.unpack(rootdir)
+            </literallayout>
+            This code unpacks the downloaded files to the
+            specified by <filename>WORKDIR</filename>.
+            <note>
+                For convenience, the naming in these examples matches
+                the variables used by OpenEmbedded.
+                If you want to see the above code in action, examine
+                the OpenEmbedded class file <filename>base.bbclass</filename>.
+            </note>
+            The <filename>SRC_URI</filename> and <filename>WORKDIR</filename>
+            variables are not hardcoded into the fetcher, since those fetcher
+            methods can be (and are) called with different variable names.
+            In OpenEmbedded for example, the shared state (sstate) code uses
+            the fetch module to fetch the sstate files.
+        </para>
+
+        <para>
+            When the <filename>download()</filename> method is called,
+            BitBake tries to resolve the URLs by looking for source files
+            in a specific search order:
+            <itemizedlist>
+                <listitem><para><emphasis>Pre-mirror Sites:</emphasis>
+                    BitBake first uses pre-mirrors to try and find source files.
+                    These locations are defined using the
+                    <link linkend='var-PREMIRRORS'><filename>PREMIRRORS</filename></link>
+                    variable.
+                    </para></listitem>
+                <listitem><para><emphasis>Source URI:</emphasis>
+                    If pre-mirrors fail, BitBake uses the original URL (e.g from
+                    <filename>SRC_URI</filename>).
+                    </para></listitem>
+                <listitem><para><emphasis>Mirror Sites:</emphasis>
+                    If fetch failures occur, BitBake next uses mirror locations as
+                    defined by the
+                    <link linkend='var-MIRRORS'><filename>MIRRORS</filename></link>
+                    variable.
+                    </para></listitem>
+            </itemizedlist>
+        </para>
+
+        <para>
+            For each URL passed to the fetcher, the fetcher
+            calls the submodule that handles that particular URL type.
+            This behavior can be the source of some confusion when you
+            are providing URLs for the <filename>SRC_URI</filename>
+            variable.
+            Consider the following two URLs:
+            <literallayout class='monospaced'>
+     http://git.yoctoproject.org/git/poky;protocol=git
+     git://git.yoctoproject.org/git/poky;protocol=http
+            </literallayout>
+            In the former case, the URL is passed to the
+            <filename>wget</filename> fetcher, which does not
+            understand "git".
+            Therefore, the latter case is the correct form since the
+            Git fetcher does know how to use HTTP as a transport.
+        </para>
+
+        <para>
+            Here are some examples that show commonly used mirror
+            definitions:
+            <literallayout class='monospaced'>
+     PREMIRRORS ?= "\
+         bzr://.*/.*   http://somemirror.org/sources/ \n \
+         cvs://.*/.*   http://somemirror.org/sources/ \n \
+         git://.*/.*   http://somemirror.org/sources/ \n \
+         hg://.*/.*    http://somemirror.org/sources/ \n \
+         osc://.*/.*   http://somemirror.org/sources/ \n \
+         p4://.*/.*    http://somemirror.org/sources/ \n \
+         svn://.*/.*   http://somemirror.org/sources/ \n"
+
+     MIRRORS =+ "\
+         ftp://.*/.*      http://somemirror.org/sources/ \n \
+         http://.*/.*     http://somemirror.org/sources/ \n \
+         https://.*/.*    http://somemirror.org/sources/ \n"
+            </literallayout>
+            It is useful to note that BitBake supports
+            cross-URLs.
+            It is possible to mirror a Git repository on an HTTP
+            server as a tarball.
+            This is what the <filename>git://</filename> mapping in
+            the previous example does.
+        </para>
+
+        <para>
+            Since network accesses are slow, Bitbake maintains a
+            cache of files downloaded from the network.
+            Any source files that are not local (i.e.
+            downloaded from the Internet) are placed into the download
+            directory, which is specified by the
+            <link linkend='var-DL_DIR'><filename>DL_DIR</filename></link>
+            variable.
+        </para>
+
+        <para>
+            File integrity is of key importance for reproducing builds.
+            For non-local archive downloads, the fetcher code can verify
+            SHA-256 and MD5 checksums to ensure the archives have been
+            downloaded correctly.
+            You can specify these checksums by using the
+            <filename>SRC_URI</filename> variable with the appropriate
+            varflags as follows:
+            <literallayout class='monospaced'>
+     SRC_URI[md5sum] = "<replaceable>value</replaceable>"
+     SRC_URI[sha256sum] = "<replaceable>value</replaceable>"
+            </literallayout>
+            You can also specify the checksums as parameters on the
+            <filename>SRC_URI</filename> as shown below:
+            <literallayout class='monospaced'>
+     SRC_URI = "http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d"
+            </literallayout>
+            If multiple URIs exist, you can specify the checksums either
+            directly as in the previous example, or you can name the URLs.
+            The following syntax shows how you name the URIs:
+            <literallayout class='monospaced'>
+     SRC_URI = "http://example.com/foobar.tar.bz2;name=foo"
+     SRC_URI[foo.md5sum] = 4a8e0f237e961fd7785d19d07fdb994d
+            </literallayout>
+            After a file has been downloaded and has had its checksum checked,
+            a ".done" stamp is placed in <filename>DL_DIR</filename>.
+            BitBake uses this stamp during subsequent builds to avoid
+            downloading or comparing a checksum for the file again.
+            <note>
+                It is assumed that local storage is safe from data corruption.
+                If this were not the case, there would be bigger issues to worry about.
+            </note>
+        </para>
+
+        <para>
+            If
+            <link linkend='var-BB_STRICT_CHECKSUM'><filename>BB_STRICT_CHECKSUM</filename></link>
+            is set, any download without a checksum triggers an
+            error message.
+            The
+            <link linkend='var-BB_NO_NETWORK'><filename>BB_NO_NETWORK</filename></link>
+            variable can be used to make any attempted network access a fatal
+            error, which is useful for checking that mirrors are complete

+            <note>
+               Because URL parameters are delimited by semi-colons, this can
+               introduce ambiguity when parsing URLs that also contain semi-colons,
+               for example:
+                <literallayout class='monospaced'>
+     SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git;a=snapshot;h=a5dd47"
+                </literallayout>
+               Such URLs should should be modified by replacing semi-colons with '&amp;' characters:
+               <literallayout class='monospaced'>
+     SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&amp;a=snapshot&amp;h=a5dd47"
+                </literallayout>
+                In most cases this should work. Treating semi-colons and '&amp;' in queries
+                identically is recommended by the World Wide Web Consortium (W3C).
+                Note that due to the nature of the URL, you may have to specify the name
+                of the downloaded file as well:
+              <literallayout class='monospaced'>
+     SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&amp;a=snapshot&amp;h=a5dd47;downloadfilename=myfile.bz2"

-Hello World Example
-===================
-
-BitBake Hello World
-===================
-
-The simplest example commonly used to demonstrate any new programming
-language or tool is the "`Hello
-World <http://en.wikipedia.org/wiki/Hello_world_program>`__" example.
-This appendix demonstrates, in tutorial form, Hello World within the
-context of BitBake. The tutorial describes how to create a new project
-and the applicable metadata files necessary to allow BitBake to build
-it.
-
-Obtaining BitBake
-=================
-
-See the :ref:`bitbake-user-manual/bitbake-user-manual-intro:obtaining bitbake` section for
-information on how to obtain BitBake. Once you have the source code on
-your machine, the BitBake directory appears as follows::

-
-At this point, you should have BitBake cloned to a directory that
-matches the previous listing except for dates and user names.
-
-Setting Up the BitBake Environment
-==================================
-
-First, you need to be sure that you can run BitBake. Set your working
-directory to where your local BitBake files are and run the following
-command::
-
-  $ ./bin/bitbake --version
-  BitBake Build Tool Core version 2.3.1
-
-The console output tells you what version
-you are running.
-
-The recommended method to run BitBake is from a directory of your
-choice. To be able to run BitBake from any directory, you need to add
-the executable binary to your binary to your shell's environment
-``PATH`` variable. First, look at your current ``PATH`` variable by
-entering the following::
-
-  $ echo $PATH
-
-Next, add the directory location
-for the BitBake binary to the ``PATH``. Here is an example that adds the
-``/home/scott-lenovo/bitbake/bin`` directory to the front of the
-``PATH`` variable::
-
-  $ export PATH=/home/scott-lenovo/bitbake/bin:$PATH
-
-You should now be able to enter the ``bitbake`` command from the command
-line while working from any directory.
-
-The Hello World Example
-=======================
-
-The overall goal of this exercise is to build a complete "Hello World"
-example utilizing task and layer concepts. Because this is how modern
-projects such as OpenEmbedded and the Yocto Project utilize BitBake, the
-example provides an excellent starting point for understanding BitBake.
-
-To help you understand how to use BitBake to build targets, the example
-starts with nothing but the ``bitbake`` command, which causes BitBake to
-fail and report problems. The example progresses by adding pieces to the
-build to eventually conclude with a working, minimal "Hello World"
-example.
-
-While every attempt is made to explain what is happening during the
-example, the descriptions cannot cover everything. You can find further
-information throughout this manual. Also, you can actively participate
-in the :oe_lists:`/g/bitbake-devel`
-discussion mailing list about the BitBake build tool.
-
-.. note::
-
-   This example was inspired by and drew heavily from
-   `Mailing List post - The BitBake equivalent of "Hello, World!"
-   <https://www.mail-archive.com/yocto@yoctoproject.org/msg09379.html>`_.
-
-As stated earlier, the goal of this example is to eventually compile
-"Hello World". However, it is unknown what BitBake needs and what you
-have to provide in order to achieve that goal. Recall that BitBake
-utilizes three types of metadata files:
-:ref:`bitbake-user-manual/bitbake-user-manual-intro:configuration files`,
-:ref:`bitbake-user-manual/bitbake-user-manual-intro:classes`, and
-:ref:`bitbake-user-manual/bitbake-user-manual-intro:recipes`.
-But where do they go? How does BitBake find
-them? BitBake's error messaging helps you answer these types of
-questions and helps you better understand exactly what is going on.
-
-Following is the complete "Hello World" example.
-
-#.  **Create a Project Directory:** First, set up a directory for the
-    "Hello World" project. Here is how you can do so in your home
-    directory::
-
-      $ mkdir ~/hello
-      $ cd ~/hello
-
-    This is the directory that
-    BitBake will use to do all of its work. You can use this directory
-    to keep all the metafiles needed by BitBake. Having a project
-    directory is a good way to isolate your project.
-
-#.  **Run BitBake:** At this point, you have nothing but a project
-    directory. Run the ``bitbake`` command and see what it does::
-
-       $ bitbake
-       ERROR: The BBPATH variable is not set and bitbake did not find a conf/bblayers.conf file in the expected location.
-       Maybe you accidentally invoked bitbake from the wrong directory?
-
-    When you run BitBake, it begins looking for metadata files. The
-    :term:`BBPATH` variable is what tells BitBake where
-    to look for those files. :term:`BBPATH` is not set and you need to set
-    it. Without :term:`BBPATH`, BitBake cannot find any configuration files
-    (``.conf``) or recipe files (``.bb``) at all. BitBake also cannot
-    find the ``bitbake.conf`` file.
-
-#.  **Setting BBPATH:** For this example, you can set :term:`BBPATH` in
-    the same manner that you set ``PATH`` earlier in the appendix. You
-    should realize, though, that it is much more flexible to set the
-    :term:`BBPATH` variable up in a configuration file for each project.
-
-    From your shell, enter the following commands to set and export the
-    :term:`BBPATH` variable::
-
-      $ BBPATH="projectdirectory"
-      $ export BBPATH
-
-    Use your actual project directory in the command. BitBake uses that
-    directory to find the metadata it needs for your project.
-
-    .. note::
-
-       When specifying your project directory, do not use the tilde
-       ("~") character as BitBake does not expand that character as the
-       shell would.
-
-#.  **Run BitBake:** Now that you have :term:`BBPATH` defined, run the
-    ``bitbake`` command again::
-
-       $ bitbake
-       ERROR: Unable to parse /home/scott-lenovo/bitbake/lib/bb/parse/__init__.py
-       Traceback (most recent call last):
-       File "/home/scott-lenovo/bitbake/lib/bb/parse/__init__.py", line 127, in resolve_file(fn='conf/bitbake.conf', d=<bb.data_smart.DataSmart object at 0x7f22919a3df0>):
-             if not newfn:
-       >            raise IOError(errno.ENOENT, "file %s not found in %s" % (fn, bbpath))
-             fn = newfn
-       FileNotFoundError: [Errno 2] file conf/bitbake.conf not found in <projectdirectory>
-
-
-    This sample output shows that BitBake could not find the
-    ``conf/bitbake.conf`` file in the project directory. This file is
-    the first thing BitBake must find in order to build a target. And,
-    since the project directory for this example is empty, you need to
-    provide a ``conf/bitbake.conf`` file.
-
-#.  **Creating conf/bitbake.conf:** The ``conf/bitbake.conf`` includes
-    a number of configuration variables BitBake uses for metadata and
-    recipe files. For this example, you need to create the file in your
-    project directory and define some key BitBake variables. For more
-    information on the ``bitbake.conf`` file, see
-    https://git.openembedded.org/bitbake/tree/conf/bitbake.conf.
-
-    Use the following commands to create the ``conf`` directory in the
-    project directory::
-
-      $ mkdir conf
-
-    From within the ``conf`` directory,
-    use some editor to create the ``bitbake.conf`` so that it contains
-    the following::
-
-       PN  = "${@bb.parse.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"
-
-       TMPDIR  = "${TOPDIR}/tmp"
-       CACHE   = "${TMPDIR}/cache"
-       STAMP   = "${TMPDIR}/${PN}/stamps"
-       T       = "${TMPDIR}/${PN}/work"
-       B       = "${TMPDIR}/${PN}"
-
-    .. note::
-
-       Without a value for :term:`PN`, the variables :term:`STAMP`, :term:`T`, and :term:`B`, prevent more
-       than one recipe from working. You can fix this by either setting :term:`PN` to
-       have a value similar to what OpenEmbedded and BitBake use in the default
-       ``bitbake.conf`` file (see previous example). Or, by manually updating each
-       recipe to set :term:`PN`. You will also need to include :term:`PN` as part of the :term:`STAMP`,
-       :term:`T`, and :term:`B` variable definitions in the ``local.conf`` file.
-
-    The ``TMPDIR`` variable establishes a directory that BitBake uses
-    for build output and intermediate files other than the cached
-    information used by the
-    :ref:`bitbake-user-manual/bitbake-user-manual-execution:setscene`
-    process. Here, the ``TMPDIR`` directory is set to ``hello/tmp``.
-
-    .. tip::
-
-       You can always safely delete the tmp directory in order to rebuild a
-       BitBake target. The build process creates the directory for you when you
-       run BitBake.
-
-    For information about each of the other variables defined in this
-    example, check :term:`PN`, :term:`TOPDIR`, :term:`CACHE`, :term:`STAMP`,
-    :term:`T` or :term:`B` to take you to the definitions in the
-    glossary.
-
-#.  **Run BitBake:** After making sure that the ``conf/bitbake.conf`` file
-    exists, you can run the ``bitbake`` command again::
-
-       $ bitbake
-       ERROR: Unable to parse /home/scott-lenovo/bitbake/lib/bb/parse/parse_py/BBHandler.py
-       Traceback (most recent call last):
-       File "/home/scott-lenovo/bitbake/lib/bb/parse/parse_py/BBHandler.py", line 67, in inherit(files=['base'], fn='configuration INHERITs', lineno=0, d=<bb.data_smart.DataSmart object at 0x7fab6815edf0>):
-             if not os.path.exists(file):
-       >            raise ParseError("Could not inherit file %s" % (file), fn, lineno)
-
-       bb.parse.ParseError: ParseError in configuration INHERITs: Could not inherit file classes/base.bbclass
-
-
-    In the sample output,
-    BitBake could not find the ``classes/base.bbclass`` file. You need
-    to create that file next.
-
-#.  **Creating classes/base.bbclass:** BitBake uses class files to
-    provide common code and functionality. The minimally required class
-    for BitBake is the ``classes/base.bbclass`` file. The ``base`` class
-    is implicitly inherited by every recipe. BitBake looks for the class
-    in the ``classes`` directory of the project (i.e ``hello/classes``
-    in this example).
-
-    Create the ``classes`` directory as follows::
-
-      $ cd $HOME/hello
-      $ mkdir classes
-
-    Move to the ``classes`` directory and then create the
-    ``base.bbclass`` file by inserting this single line::
-
-      addtask build
-
-    The minimal task that BitBake runs is the ``do_build`` task. This is
-    all the example needs in order to build the project. Of course, the
-    ``base.bbclass`` can have much more depending on which build
-    environments BitBake is supporting.
-
-#.  **Run BitBake:** After making sure that the ``classes/base.bbclass``
-    file exists, you can run the ``bitbake`` command again::
-
-       $ bitbake
-       Nothing to do. Use 'bitbake world' to build everything, or run 'bitbake --help' for usage information.
-
-    BitBake is finally reporting
-    no errors. However, you can see that it really does not have
-    anything to do. You need to create a recipe that gives BitBake
-    something to do.
-
-#.  **Creating a Layer:** While it is not really necessary for such a
-    small example, it is good practice to create a layer in which to
-    keep your code separate from the general metadata used by BitBake.
-    Thus, this example creates and uses a layer called "mylayer".
-
-    .. note::
-
-       You can find additional information on layers in the
-       ":ref:`bitbake-user-manual/bitbake-user-manual-intro:Layers`" section.
-
-    Minimally, you need a recipe file and a layer configuration file in
-    your layer. The configuration file needs to be in the ``conf``
-    directory inside the layer. Use these commands to set up the layer
-    and the ``conf`` directory::
-
-       $ cd $HOME
-       $ mkdir mylayer
-       $ cd mylayer
-       $ mkdir conf
-
-    Move to the ``conf`` directory and create a ``layer.conf`` file that has the
-    following::
-
-      BBPATH .= ":${LAYERDIR}"
-      BBFILES += "${LAYERDIR}/*.bb"
-      BBFILE_COLLECTIONS += "mylayer"
-      BBFILE_PATTERN_mylayer := "^${LAYERDIR_RE}/"
-      LAYERSERIES_CORENAMES = "hello_world_example"
-      LAYERSERIES_COMPAT_mylayer = "hello_world_example"
-
-    For information on these variables, click on :term:`BBFILES`,
-    :term:`LAYERDIR`, :term:`BBFILE_COLLECTIONS`, :term:`BBFILE_PATTERN_mylayer <BBFILE_PATTERN>`
-    or :term:`LAYERSERIES_COMPAT` to go to the definitions in the glossary.
-
-    .. note::
-
-       We are setting both ``LAYERSERIES_CORENAMES`` and :term:`LAYERSERIES_COMPAT` in this particular case, because we
-       are using bitbake without OpenEmbedded.
-       You should usually just use :term:`LAYERSERIES_COMPAT` to specify the OE-Core versions for which your layer
-       is compatible, and add the meta-openembedded layer to your project.
-
-    You need to create the recipe file next. Inside your layer at the
-    top-level, use an editor and create a recipe file named
-    ``printhello.bb`` that has the following::
-
-       DESCRIPTION = "Prints Hello World"
-       PN = 'printhello'
-       PV = '1'
-
-       python do_build() {
-          bb.plain("********************");
-          bb.plain("*                  *");
-          bb.plain("*  Hello, World!   *");
-          bb.plain("*                  *");
-          bb.plain("********************");
-       }
-
-    The recipe file simply provides
-    a description of the recipe, the name, version, and the ``do_build``
-    task, which prints out "Hello World" to the console. For more
-    information on :term:`DESCRIPTION`, :term:`PN` or :term:`PV`
-    follow the links to the glossary.
-
-#. **Run BitBake With a Target:** Now that a BitBake target exists, run
-    the command and provide that target::
-
-      $ cd $HOME/hello
-      $ bitbake printhello
-      ERROR: no recipe files to build, check your BBPATH and BBFILES?
-
-      Summary: There was 1 ERROR message shown, returning a non-zero exit code.
-
-    We have created the layer with the recipe and
-    the layer configuration file but it still seems that BitBake cannot
-    find the recipe. BitBake needs a ``conf/bblayers.conf`` that lists
-    the layers for the project. Without this file, BitBake cannot find
-    the recipe.
-
-#. **Creating conf/bblayers.conf:** BitBake uses the
-    ``conf/bblayers.conf`` file to locate layers needed for the project.
-    This file must reside in the ``conf`` directory of the project (i.e.
-    ``hello/conf`` for this example).
-
-    Set your working directory to the ``hello/conf`` directory and then
-    create the ``bblayers.conf`` file so that it contains the following::
-
-       BBLAYERS ?= " \
-           /home/<you>/mylayer \
-       "
-
-    You need to provide your own information for ``you`` in the file.
-
-#. **Run BitBake With a Target:** Now that you have supplied the
-    ``bblayers.conf`` file, run the ``bitbake`` command and provide the
-    target::
-
-       $ bitbake printhello
-       Loading cache: 100% |

-       NOTE: Tasks Summary: Attempted 1 tasks of which 0 didn't need to be rerun and all succeeded.
-
-    .. note::
-
-       After the first execution, re-running bitbake printhello again will not
-       result in a BitBake run that prints the same console output. The reason
-       for this is that the first time the printhello.bb recipe's do_build task
-       executes successfully, BitBake writes a stamp file for the task. Thus,
-       the next time you attempt to run the task using that same bitbake
-       command, BitBake notices the stamp and therefore determines that the task
-       does not need to be re-run. If you delete the tmp directory or run
-       bitbake -c clean printhello and then re-run the build, the "Hello,
-       World!" message will be printed again.

+            First, you need to be sure that you can run BitBake.
+            Set your working directory to where your local BitBake
+            files are and run the following command:
+            <literallayout class='monospaced'>
+     $ ./bin/bitbake --version
+     BitBake Build Tool Core version 1.23.0, bitbake version 1.23.0

+            The console output tells you what version you are running.
+        </para>
+
+        <para>
+            The recommended method to run BitBake is from a directory of your
+            choice.
+            To be able to run BitBake from any directory, you need to add the
+            executable binary to your binary to your shell's environment
+            <filename>PATH</filename> variable.
+            First, look at your current <filename>PATH</filename> variable
+            by entering the following:
+            <literallayout class='monospaced'>
+     $ echo $PATH
+            </literallayout>
+            Next, add the directory location for the BitBake binary to the
+            <filename>PATH</filename>.
+            Here is an example that adds the
+            <filename>/home/scott-lenovo/bitbake/bin</filename> directory
+            to the front of the <filename>PATH</filename> variable:
+            <literallayout class='monospaced'>
+     $ export PATH=/home/scott-lenovo/bitbake/bin:$PATH
+            </literallayout>
+            You should now be able to enter the <filename>bitbake</filename>
+            command from the command line while working from any directory.

+            The overall goal of this exercise is to build a

+            Because this is how modern projects such as OpenEmbedded and

+            As stated earlier, the goal of this example

+            However, it is unknown what BitBake needs and what you have
+            to provide in order to achieve that goal.

-
-Welcome to the BitBake User Manual. This manual provides information on
-the BitBake tool. The information attempts to be as independent as
-possible regarding systems that use BitBake, such as OpenEmbedded and
-the Yocto Project. In some cases, scenarios or examples within the
-context of a build system are used in the manual to help with
-understanding. For these cases, the manual clearly states the context.
-
-.. _intro:
-
-Introduction
-============
-
-Fundamentally, BitBake is a generic task execution engine that allows
-shell and Python tasks to be run efficiently and in parallel while
-working within complex inter-task dependency constraints. One of
-BitBake's main users, OpenEmbedded, takes this core and builds embedded
-Linux software stacks using a task-oriented approach.
-
-Conceptually, BitBake is similar to GNU Make in some regards but has
-significant differences:
-
--  BitBake executes tasks according to the provided metadata that builds up
-   the tasks. Metadata is stored in recipe (``.bb``) and related recipe
-   "append" (``.bbappend``) files, configuration (``.conf``) and
-   underlying include (``.inc``) files, and in class (``.bbclass``)
-   files. The metadata provides BitBake with instructions on what tasks
-   to run and the dependencies between those tasks.
-
--  BitBake includes a fetcher library for obtaining source code from
-   various places such as local files, source control systems, or
-   websites.
-
--  The instructions for each unit to be built (e.g. a piece of software)
-   are known as "recipe" files and contain all the information about the
-   unit (dependencies, source file locations, checksums, description and
-   so on).
-
--  BitBake includes a client/server abstraction and can be used from a
-   command line or used as a service over XML-RPC and has several
-   different user interfaces.
-
-History and Goals
-=================
-
-BitBake was originally a part of the OpenEmbedded project. It was
-inspired by the Portage package management system used by the Gentoo
-Linux distribution. On December 7, 2004, OpenEmbedded project team
-member Chris Larson split the project into two distinct pieces:
-
--  BitBake, a generic task executor
-
--  OpenEmbedded, a metadata set utilized by BitBake
-
-Today, BitBake is the primary basis of the
-`OpenEmbedded <https://www.openembedded.org/>`__ project, which is being
-used to build and maintain Linux distributions such as the `Poky
-Reference Distribution <https://www.yoctoproject.org/software-item/poky/>`__,
-developed under the umbrella of the `Yocto Project <https://www.yoctoproject.org>`__.
-
-Prior to BitBake, no other build tool adequately met the needs of an
-aspiring embedded Linux distribution. All of the build systems used by
-traditional desktop Linux distributions lacked important functionality,
-and none of the ad hoc Buildroot-based systems, prevalent in the
-embedded space, were scalable or maintainable.
-
-Some important original goals for BitBake were:
-
--  Handle cross-compilation.
-
--  Handle inter-package dependencies (build time on target architecture,
-   build time on native architecture, and runtime).
-
--  Support running any number of tasks within a given package,
-   including, but not limited to, fetching upstream sources, unpacking
-   them, patching them, configuring them, and so forth.
-
--  Be Linux distribution agnostic for both build and target systems.
-
--  Be architecture agnostic.
-
--  Support multiple build and target operating systems (e.g. Cygwin, the
-   BSDs, and so forth).
-
--  Be self-contained, rather than tightly integrated into the build
-   machine's root filesystem.
-
--  Handle conditional metadata on the target architecture, operating
-   system, distribution, and machine.
-
--  Be easy to use the tools to supply local metadata and packages
-   against which to operate.
-
--  Be easy to use BitBake to collaborate between multiple projects for
-   their builds.
-
--  Provide an inheritance mechanism to share common metadata between
-   many packages.
-
-Over time it became apparent that some further requirements were
-necessary:
-
--  Handle variants of a base recipe (e.g. native, sdk, and multilib).
-
--  Split metadata into layers and allow layers to enhance or override
-   other layers.
-
--  Allow representation of a given set of input variables to a task as a
-   checksum. Based on that checksum, allow acceleration of builds with
-   prebuilt components.
-
-BitBake satisfies all the original requirements and many more with
-extensions being made to the basic functionality to reflect the
-additional requirements. Flexibility and power have always been the
-priorities. BitBake is highly extensible and supports embedded Python
-code and execution of any arbitrary tasks.
-
-.. _Concepts:
-
-Concepts
-========
-
-BitBake is a program written in the Python language. At the highest
-level, BitBake interprets metadata, decides what tasks are required to
-run, and executes those tasks. Similar to GNU Make, BitBake controls how
-software is built. GNU Make achieves its control through "makefiles",
-while BitBake uses "recipes".
-
-BitBake extends the capabilities of a simple tool like GNU Make by
-allowing for the definition of much more complex tasks, such as
-assembling entire embedded Linux distributions.
-
-The remainder of this section introduces several concepts that should be
-understood in order to better leverage the power of BitBake.
-
-Recipes
--------
-
-BitBake Recipes, which are denoted by the file extension ``.bb``, are
-the most basic metadata files. These recipe files provide BitBake with
-the following:
-
--  Descriptive information about the package (author, homepage, license,
-   and so on)
-
--  The version of the recipe
-
--  Existing dependencies (both build and runtime dependencies)
-
--  Where the source code resides and how to fetch it
-
--  Whether the source code requires any patches, where to find them, and
-   how to apply them
-
--  How to configure and compile the source code
-
--  How to assemble the generated artifacts into one or more installable
-   packages
-
--  Where on the target machine to install the package or packages
-   created
-
-Within the context of BitBake, or any project utilizing BitBake as its
-build system, files with the ``.bb`` extension are referred to as
-recipes.
-
-.. note::
-
-   The term "package" is also commonly used to describe recipes.
-   However, since the same word is used to describe packaged output from
-   a project, it is best to maintain a single descriptive term -
-   "recipes". Put another way, a single "recipe" file is quite capable
-   of generating a number of related but separately installable
-   "packages". In fact, that ability is fairly common.
-
-Configuration Files
--------------------
-
-Configuration files, which are denoted by the ``.conf`` extension,
-define various configuration variables that govern the project's build
-process. These files fall into several areas that define machine
-configuration, distribution configuration, possible compiler tuning,
-general common configuration, and user configuration. The main
-configuration file is the sample ``bitbake.conf`` file, which is located
-within the BitBake source tree ``conf`` directory.
-
-Classes
--------
-
-Class files, which are denoted by the ``.bbclass`` extension, contain
-information that is useful to share between metadata files. The BitBake
-source tree currently comes with one class metadata file called
-``base.bbclass``. You can find this file in the ``classes`` directory.
-The ``base.bbclass`` class files is special since it is always included
-automatically for all recipes and classes. This class contains
-definitions for standard basic tasks such as fetching, unpacking,
-configuring (empty by default), compiling (runs any Makefile present),
-installing (empty by default) and packaging (empty by default). These
-tasks are often overridden or extended by other classes added during the
-project development process.
-
-Layers
-------
-
-Layers allow you to isolate different types of customizations from each
-other. While you might find it tempting to keep everything in one layer
-when working on a single project, the more modular your metadata, the
-easier it is to cope with future changes.
-
-To illustrate how you can use layers to keep things modular, consider
-customizations you might make to support a specific target machine.
-These types of customizations typically reside in a special layer,
-rather than a general layer, called a Board Support Package (BSP) layer.
-Furthermore, the machine customizations should be isolated from recipes
-and metadata that support a new GUI environment, for example. This
-situation gives you a couple of layers: one for the machine
-configurations and one for the GUI environment. It is important to
-understand, however, that the BSP layer can still make machine-specific
-additions to recipes within the GUI environment layer without polluting
-the GUI layer itself with those machine-specific changes. You can
-accomplish this through a recipe that is a BitBake append
-(``.bbappend``) file.
-
-.. _append-bbappend-files:
-
-Append Files
-------------
-
-Append files, which are files that have the ``.bbappend`` file
-extension, extend or override information in an existing recipe file.
-
-BitBake expects every append file to have a corresponding recipe file.
-Furthermore, the append file and corresponding recipe file must use the
-same root filename. The filenames can differ only in the file type
-suffix used (e.g. ``formfactor_0.0.bb`` and
-``formfactor_0.0.bbappend``).
-
-Information in append files extends or overrides the information in the
-underlying, similarly-named recipe files.
-
-When you name an append file, you can use the "``%``" wildcard character
-to allow for matching recipe names. For example, suppose you have an
-append file named as follows::
-
-  busybox_1.21.%.bbappend
-
-That append file
-would match any ``busybox_1.21.``\ x\ ``.bb`` version of the recipe. So,
-the append file would match the following recipe names::
-
-  busybox_1.21.1.bb
-  busybox_1.21.2.bb
-  busybox_1.21.3.bb
-
-.. note::
-
-   The use of the " % " character is limited in that it only works directly in
-   front of the .bbappend portion of the append file's name. You cannot use the
-   wildcard character in any other location of the name.
-
-If the ``busybox`` recipe was updated to ``busybox_1.3.0.bb``, the
-append name would not match. However, if you named the append file
-``busybox_1.%.bbappend``, then you would have a match.
-
-In the most general case, you could name the append file something as
-simple as ``busybox_%.bbappend`` to be entirely version independent.
-
-Obtaining BitBake
-=================
-
-You can obtain BitBake several different ways:
-
--  **Cloning BitBake:** Using Git to clone the BitBake source code
-   repository is the recommended method for obtaining BitBake. Cloning
-   the repository makes it easy to get bug fixes and have access to
-   stable branches and the master branch. Once you have cloned BitBake,
-   you should use the latest stable branch for development since the
-   master branch is for BitBake development and might contain less
-   stable changes.
-
-   You usually need a version of BitBake that matches the metadata you
-   are using. The metadata is generally backwards compatible but not
-   forward compatible.
-
-   Here is an example that clones the BitBake repository::
-
-     $ git clone git://git.openembedded.org/bitbake
-
-   This command clones the BitBake
-   Git repository into a directory called ``bitbake``. Alternatively,
-   you can designate a directory after the ``git clone`` command if you
-   want to call the new directory something other than ``bitbake``. Here
-   is an example that names the directory ``bbdev``::
-
-     $ git clone git://git.openembedded.org/bitbake bbdev
-
--  **Installation using your Distribution Package Management System:**
-   This method is not recommended because the BitBake version that is
-   provided by your distribution, in most cases, is several releases
-   behind a snapshot of the BitBake repository.
-
--  **Taking a snapshot of BitBake:** Downloading a snapshot of BitBake
-   from the source code repository gives you access to a known branch or
-   release of BitBake.
-
-      .. note::
-
-         Cloning the Git repository, as described earlier, is the preferred
-         method for getting BitBake. Cloning the repository makes it easier
-         to update as patches are added to the stable branches.
-
-   The following example downloads a snapshot of BitBake version 1.17.0::
-
-     $ wget https://git.openembedded.org/bitbake/snapshot/bitbake-1.17.0.tar.gz
-     $ tar zxpvf bitbake-1.17.0.tar.gz
-
-   After extraction of the tarball using
-   the tar utility, you have a directory entitled ``bitbake-1.17.0``.
-
--  **Using the BitBake that Comes With Your Build Checkout:** A final
-   possibility for getting a copy of BitBake is that it already comes
-   with your checkout of a larger BitBake-based build system, such as
-   Poky. Rather than manually checking out individual layers and gluing
-   them together yourself, you can check out an entire build system. The
-   checkout will already include a version of BitBake that has been
-   thoroughly tested for compatibility with the other components. For
-   information on how to check out a particular BitBake-based build
-   system, consult that build system's supporting documentation.

-
-The BitBake Command
-===================
-
-The ``bitbake`` command is the primary interface to the BitBake tool.
-This section presents the BitBake command syntax and provides several
-execution examples.
-
-Usage and syntax
-----------------
-
-Following is the usage and syntax for BitBake::
-
-   $ bitbake -h
-   Usage: bitbake [options] [recipename/target recipe:do_task ...]
-
-       Executes the specified task (default is 'build') for a given set of target recipes (.bb files).
-       It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which
-       will provide the layer, BBFILES and other configuration information.
-
-   Options:
-     --version             show program's version number and exit
-     -h, --help            show this help message and exit
-     -b BUILDFILE, --buildfile=BUILDFILE
-                           Execute tasks from a specific .bb recipe directly.
-                           WARNING: Does not handle any dependencies from other
-                           recipes.
-     -k, --continue        Continue as much as possible after an error. While the
-                           target that failed and anything depending on it cannot
-                           be built, as much as possible will be built before
-                           stopping.
-     -f, --force           Force the specified targets/task to run (invalidating
-                           any existing stamp file).
-     -c CMD, --cmd=CMD     Specify the task to execute. The exact options
-                           available depend on the metadata. Some examples might
-                           be 'compile' or 'populate_sysroot' or 'listtasks' may
-                           give a list of the tasks available.
-     -C INVALIDATE_STAMP, --clear-stamp=INVALIDATE_STAMP
-                           Invalidate the stamp for the specified task such as
-                           'compile' and then run the default task for the
-                           specified target(s).
-     -r PREFILE, --read=PREFILE
-                           Read the specified file before bitbake.conf.
-     -R POSTFILE, --postread=POSTFILE
-                           Read the specified file after bitbake.conf.
-     -v, --verbose         Enable tracing of shell tasks (with 'set -x'). Also
-                           print bb.note(...) messages to stdout (in addition to
-                           writing them to ${T}/log.do_&lt;task&gt;).
-     -D, --debug           Increase the debug level. You can specify this more
-                           than once. -D sets the debug level to 1, where only
-                           bb.debug(1, ...) messages are printed to stdout; -DD
-                           sets the debug level to 2, where both bb.debug(1, ...)
-                           and bb.debug(2, ...) messages are printed; etc.
-                           Without -D, no debug messages are printed. Note that
-                           -D only affects output to stdout. All debug messages
-                           are written to ${T}/log.do_taskname, regardless of the
-                           debug level.
-     -q, --quiet           Output less log message data to the terminal. You can
-                           specify this more than once.
-     -n, --dry-run         Don't execute, just go through the motions.
-     -S SIGNATURE_HANDLER, --dump-signatures=SIGNATURE_HANDLER
-                           Dump out the signature construction information, with
-                           no task execution. The SIGNATURE_HANDLER parameter is
-                           passed to the handler. Two common values are none and
-                           printdiff but the handler may define more/less. none
-                           means only dump the signature, printdiff means compare
-                           the dumped signature with the cached one.
-     -p, --parse-only      Quit after parsing the BB recipes.
-     -s, --show-versions   Show current and preferred versions of all recipes.
-     -e, --environment     Show the global or per-recipe environment complete
-                           with information about where variables were
-                           set/changed.
-     -g, --graphviz        Save dependency tree information for the specified
-                           targets in the dot syntax.
-     -I EXTRA_ASSUME_PROVIDED, --ignore-deps=EXTRA_ASSUME_PROVIDED
-                           Assume these dependencies don't exist and are already
-                           provided (equivalent to ASSUME_PROVIDED). Useful to
-                           make dependency graphs more appealing
-     -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
-                           Show debug logging for the specified logging domains
-     -P, --profile         Profile the command and save reports.
-     -u UI, --ui=UI        The user interface to use (knotty, ncurses, taskexp or
-                           teamcity - default knotty).
-     --token=XMLRPCTOKEN   Specify the connection token to be used when
-                           connecting to a remote server.
-     --revisions-changed   Set the exit code depending on whether upstream
-                           floating revisions have changed or not.
-     --server-only         Run bitbake without a UI, only starting a server
-                           (cooker) process.
-     -B BIND, --bind=BIND  The name/address for the bitbake xmlrpc server to bind
-                           to.
-     -T SERVER_TIMEOUT, --idle-timeout=SERVER_TIMEOUT
-                           Set timeout to unload bitbake server due to
-                           inactivity, set to -1 means no unload, default:
-                           Environment variable BB_SERVER_TIMEOUT.
-     --no-setscene         Do not run any setscene tasks. sstate will be ignored
-                           and everything needed, built.
-     --skip-setscene       Skip setscene tasks if they would be executed. Tasks
-                           previously restored from sstate will be kept, unlike
-                           --no-setscene
-     --setscene-only       Only run setscene tasks, don't run any real tasks.
-     --remote-server=REMOTE_SERVER
-                           Connect to the specified server.

-Examples
---------
-
-This section presents some examples showing how to use BitBake.
-
-.. _example-executing-a-task-against-a-single-recipe:
-
-Executing a Task Against a Single Recipe
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Executing tasks for a single recipe file is relatively simple. You
-specify the file in question, and BitBake parses it and executes the
-specified task. If you do not specify a task, BitBake executes the
-default task, which is "build". BitBake obeys inter-task dependencies
-when doing so.
-
-The following command runs the build task, which is the default task, on
-the ``foo_1.0.bb`` recipe file::
-
-  $ bitbake -b foo_1.0.bb
-
-The following command runs the clean task on the ``foo.bb`` recipe file::
-
-  $ bitbake -b foo.bb -c clean
-
-.. note::
-
-   The "-b" option explicitly does not handle recipe dependencies. Other
-   than for debugging purposes, it is instead recommended that you use
-   the syntax presented in the next section.
-
-Executing Tasks Against a Set of Recipe Files
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are a number of additional complexities introduced when one wants
-to manage multiple ``.bb`` files. Clearly there needs to be a way to
-tell BitBake what files are available and, of those, which you want to
-execute. There also needs to be a way for each recipe to express its
-dependencies, both for build-time and runtime. There must be a way for
-you to express recipe preferences when multiple recipes provide the same
-functionality, or when there are multiple versions of a recipe.
-
-The ``bitbake`` command, when not using "--buildfile" or "-b" only
-accepts a "PROVIDES". You cannot provide anything else. By default, a
-recipe file generally "PROVIDES" its "packagename" as shown in the
-following example::
-
-  $ bitbake foo
-
-This next example "PROVIDES" the
-package name and also uses the "-c" option to tell BitBake to just
-execute the ``do_clean`` task::
-
-  $ bitbake -c clean foo
-
-Executing a List of Task and Recipe Combinations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The BitBake command line supports specifying different tasks for
-individual targets when you specify multiple targets. For example,
-suppose you had two targets (or recipes) ``myfirstrecipe`` and
-``mysecondrecipe`` and you needed BitBake to run ``taskA`` for the first
-recipe and ``taskB`` for the second recipe::
-
-  $ bitbake myfirstrecipe:do_taskA mysecondrecipe:do_taskB
-
-Generating Dependency Graphs
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-BitBake is able to generate dependency graphs using the ``dot`` syntax.
-You can convert these graphs into images using the ``dot`` tool from
-`Graphviz <http://www.graphviz.org>`__.
-
-When you generate a dependency graph, BitBake writes two files to the
-current working directory:
-
--  ``task-depends.dot``: Shows dependencies between tasks. These
-   dependencies match BitBake's internal task execution list.
-
--  ``pn-buildlist``: Shows a simple list of targets that are to be
-   built.
-
-To stop depending on common depends, use the ``-I`` depend option and
-BitBake omits them from the graph. Leaving this information out can
-produce more readable graphs. This way, you can remove from the graph
-:term:`DEPENDS` from inherited classes such as ``base.bbclass``.
-
-Here are two examples that create dependency graphs. The second example
-omits depends common in OpenEmbedded from the graph::
-
-  $ bitbake -g foo
-
-  $ bitbake -g -I virtual/kernel -I eglibc foo
-
-Executing a Multiple Configuration Build
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-BitBake is able to build multiple images or packages using a single
-command where the different targets require different configurations
-(multiple configuration builds). Each target, in this scenario, is
-referred to as a "multiconfig".
-
-To accomplish a multiple configuration build, you must define each
-target's configuration separately using a parallel configuration file in
-the build directory. The location for these multiconfig configuration
-files is specific. They must reside in the current build directory in a
-sub-directory of ``conf`` named ``multiconfig``. Following is an example
-for two separate targets:
-
-.. image:: figures/bb_multiconfig_files.png
-   :align: center
-
-The reason for this required file hierarchy is because the :term:`BBPATH`
-variable is not constructed until the layers are parsed. Consequently,
-using the configuration file as a pre-configuration file is not possible
-unless it is located in the current working directory.
-
-Minimally, each configuration file must define the machine and the
-temporary directory BitBake uses for the build. Suggested practice
-dictates that you do not overlap the temporary directories used during
-the builds.
-
-Aside from separate configuration files for each target, you must also
-enable BitBake to perform multiple configuration builds. Enabling is
-accomplished by setting the
-:term:`BBMULTICONFIG` variable in the
-``local.conf`` configuration file. As an example, suppose you had
-configuration files for ``target1`` and ``target2`` defined in the build
-directory. The following statement in the ``local.conf`` file both
-enables BitBake to perform multiple configuration builds and specifies
-the two extra multiconfigs::
-
-  BBMULTICONFIG = "target1 target2"
-
-Once the target configuration files are in place and BitBake has been
-enabled to perform multiple configuration builds, use the following
-command form to start the builds::
-
-  $ bitbake [mc:multiconfigname:]target [[[mc:multiconfigname:]target] ... ]
-
-Here is an example for two extra multiconfigs: ``target1`` and ``target2``::
-
-  $ bitbake mc::target mc:target1:target mc:target2:target
-
-.. _bb-enabling-multiple-configuration-build-dependencies:
-
-Enabling Multiple Configuration Build Dependencies
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Sometimes dependencies can exist between targets (multiconfigs) in a
-multiple configuration build. For example, suppose that in order to
-build an image for a particular architecture, the root filesystem of
-another build for a different architecture needs to exist. In other
-words, the image for the first multiconfig depends on the root
-filesystem of the second multiconfig. This dependency is essentially
-that the task in the recipe that builds one multiconfig is dependent on
-the completion of the task in the recipe that builds another
-multiconfig.
-
-To enable dependencies in a multiple configuration build, you must
-declare the dependencies in the recipe using the following statement
-form::
-
-  task_or_package[mcdepends] = "mc:from_multiconfig:to_multiconfig:recipe_name:task_on_which_to_depend"
-
-To better show how to use this statement, consider an example with two
-multiconfigs: ``target1`` and ``target2``::
-
-  image_task[mcdepends] = "mc:target1:target2:image2:rootfs_task"
-
-In this example, the
-``from_multiconfig`` is "target1" and the ``to_multiconfig`` is "target2". The
-task on which the image whose recipe contains image_task depends on the
-completion of the rootfs_task used to build out image2, which is
-associated with the "target2" multiconfig.
-
-Once you set up this dependency, you can build the "target1" multiconfig
-using a BitBake command as follows::
-
-  $ bitbake mc:target1:image1
-
-This command executes all the tasks needed to create ``image1`` for the "target1"
-multiconfig. Because of the dependency, BitBake also executes through
-the ``rootfs_task`` for the "target2" multiconfig build.
-
-Having a recipe depend on the root filesystem of another build might not
-seem that useful. Consider this change to the statement in the image1
-recipe::
-
-  image_task[mcdepends] = "mc:target1:target2:image2:image_task"
-
-In this case, BitBake must create ``image2`` for the "target2" build since
-the "target1" build depends on it.
-
-Because "target1" and "target2" are enabled for multiple configuration
-builds and have separate configuration files, BitBake places the
-artifacts for each build in the respective temporary build directories.

+
+        <para>
+            BitBake was originally a part of the OpenEmbedded project.
+            It was inspired by the Portage package management system
+            used by the Gentoo Linux distribution.
+            On December 7, 2004, OpenEmbedded project team member
+            Chris Larson split the project into two distinct pieces:
+            <itemizedlist>

+                <listitem><para>OpenEmbedded, a metadata set utilized by
+                    BitBake</para></listitem>
+            </itemizedlist>
+            Today, BitBake is the primary basis of the
+            <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink>
+            project, which is being used to build and maintain Linux
+            distributions such as the
+            <ulink url='http://www.angstrom-distribution.org/'>Angstrom Distribution</ulink>,
+            and which is also being used as the build tool for Linux projects
+            such as the

+        </para>
+
+        <para>
+            Prior to BitBake, no other build tool adequately met the needs of
+            an aspiring embedded Linux distribution.
+            All of the build systems used by traditional desktop Linux
+            distributions lacked important functionality, and none of the
+            ad hoc Buildroot-based systems, prevalent in the

+            BitBake is a program written in the Python language.
+            At the highest level, BitBake interprets metadata, decides

+            Similar to GNU Make, BitBake controls how software is
+            built.

+                <note>
+                    The term "package" is also commonly used to describe recipes.
+                    However, since the same word is used to describe packaged
+                    output from a project, it is best to maintain a single
+                    descriptive term - "recipes".
+                    Put another way, a single "recipe" file is quite capable
+                    of generating a number of related but separately installable
+                    "packages".
+                    In fact, that ability is fairly common.

+                Layers allow you to isolate different types of
+                customizations from each other.
+                While you might find it tempting to keep everything in one layer
+                when working on a single project, the more modular you organize
+                your metadata, the easier it is to cope with future changes.
+            </para>
+
+            <para>
+                To illustrate how you can use layers to keep things modular,
+                consider customizations you might make to support a specific target machine.
+                These types of customizations typically reside in a special layer,
+                rather than a general layer, called a Board Support Package (BSP)
+                Layer.
+                Furthermore, the machine customizations should be isolated from
+                recipes and metadata that support a new GUI environment, for
+                example.
+                This situation gives you a couple of layers: one for the machine
+                configurations and one for the GUI environment.
+                It is important to understand, however, that the BSP layer can still
+                make machine-specific additions to recipes within
+                the GUI environment layer without polluting the GUI layer itself
+                with those machine-specific changes.
+                You can accomplish this through a recipe that is a BitBake append
+                (<filename>.bbappend</filename>) file.

+            <para>
+                BitBake expects every append file to have a corresponding recipe file.
+                Furthermore, the append file and corresponding recipe file
+                must use the same root filename.
+                The filenames can differ only in the file type suffix used
+                (e.g. <filename>formfactor_0.0.bb</filename> and
+                <filename>formfactor_0.0.bbappend</filename>).

+            </para>
+
+            <para>
+                When you name an append file, you can use the
+                wildcard character (%) to allow for matching recipe names.
+                For example, suppose you have an append file named
+                as follows:
+                <literallayout class='monospaced'>
+     busybox_1.21.%.bbappend
+                </literallayout>
+                That append file would match any <filename>busybox_1.21.x.bb</filename>
+                version of the recipe.
+                So, the append file would match the following recipe names:
+                <literallayout class='monospaced'>
+     busybox_1.21.1.bb
+     busybox_1.21.2.bb
+     busybox_1.21.3.bb
+                </literallayout>
+                If the <filename>busybox</filename> recipe was updated to
+                <filename>busybox_1.3.0.bb</filename>, the append name would not
+                match.
+                However, if you named the append file
+                <filename>busybox_1.%.bbappend</filename>, then you would have a match.
+            </para>
+
+            <para>
+                In the most general case, you could name the append file something as

+                version independent.

+

+                    Executing tasks for a single recipe file is relatively simple.
+                    You specify the file in question, and BitBake parses
+                    it and executes the specified task.
+                    If you do not specify a task, BitBake executes the default
+                    task, which is "build”.
+                    BitBake obeys inter-task dependencies when doing
+                    so.

+                    recipe file:

+                    The following command runs the clean task on the
+                    <filename>foo.bb</filename> recipe file:
+                    <literallayout class='monospaced'>

+                        The "-b" option explicitly does not handle recipe

+                    There are a number of additional complexities introduced
+                    when one wants to manage multiple <filename>.bb</filename>
+                    files.
+                    Clearly there needs to be a way to tell BitBake what
+                    files are available and, of those, which you
+                    want to execute.
+                    There also needs to be a way for each recipe
+                    to express its dependencies, both for build-time and
+                    runtime.
+                    There must be a way for you to express recipe preferences
+                    when multiple recipes provide the same functionality, or when
+                    there are multiple versions of a recipe.

+                    "--buildfile" or "-b" only accepts a "PROVIDES".
+                    You cannot provide anything else.
+                    By default, a recipe file generally "PROVIDES" its
+                    "packagename" as shown in the following example:

+                    </literallayout>
+                    This next example "PROVIDES" the package name and also uses
+                    the "-c" option to tell BitBake to just execute the
+                    <filename>do_clean</filename> task:
+                    <literallayout class='monospaced'>

+                    For example, suppose you had two targets (or recipes)

+
+                <para>
+                    BitBake is able to generate dependency graphs using
+                    the <filename>dot</filename> syntax.
+                    You can convert these graphs into images using the
+                    <filename>dot</filename> tool from
+                    <ulink url='http://www.graphviz.org'>Graphviz</ulink>.

+
+                <para>
+                    When you generate a dependency graph, BitBake writes four files

+                    Leaving this information out can produce more readable graphs.
+                    This way, you can remove from the graph

-================
-Variable Context
-================
-
-|
-
-Variables might only have an impact or can be used in certain contexts. Some
-should only be used in global files like ``.conf``, while others are intended only
-for local files like ``.bb``. This chapter aims to describe some important variable
-contexts.
-
-.. _ref-varcontext-configuration:
-
-BitBake's own configuration
-===========================
-
-Variables starting with ``BB_`` usually configure the behaviour of BitBake itself.
-For example, one could configure:
-
-- System resources, like disk space to be used (:term:`BB_DISKMON_DIRS`),
-  or the number of tasks to be run in parallel by BitBake (:term:`BB_NUMBER_THREADS`).
-
-- How the fetchers shall behave, e.g., :term:`BB_FETCH_PREMIRRORONLY` is used
-  by BitBake to determine if BitBake's fetcher shall search only
-  :term:`PREMIRRORS` for files.
-
-Those variables are usually configured globally.
-
-BitBake configuration
-=====================
-
-There are variables:
-
-- Like :term:`B` or :term:`T`, that are used to specify directories used by
-  BitBake during the build of a particular recipe. Those variables are
-  specified in ``bitbake.conf``. Some, like :term:`B`, are quite often
-  overwritten in recipes.
-
-- Starting with ``FAKEROOT``, to configure how the ``fakeroot`` command is
-  handled. Those are usually set by ``bitbake.conf`` and might get adapted in a
-  ``bbclass``.
-
-- Detailing where BitBake will store and fetch information from, for
-  data reuse between build runs like :term:`CACHE`, :term:`DL_DIR` or
-  :term:`PERSISTENT_DIR`. Those are usually global.
-
-
-Layers and files
-================
-
-Variables starting with ``LAYER`` configure how BitBake handles layers.
-Additionally, variables starting with ``BB`` configure how layers and files are
-handled. For example:
-
-- :term:`LAYERDEPENDS` is used to configure on which layers a given layer
-  depends.
-
-- The configured layers are contained in :term:`BBLAYERS` and files in
-  :term:`BBFILES`.
-
-Those variables are often used in the files ``layer.conf`` and ``bblayers.conf``.
-
-Recipes and packages
-====================
-
-Variables handling recipes and packages can be split into:
-
-- :term:`PN`, :term:`PV` or :term:`PF` for example, contain information about
-  the name or revision of a recipe or package. Usually, the default set in
-  ``bitbake.conf`` is used, but those are from time to time overwritten in
-  recipes.
-
-- :term:`SUMMARY`, :term:`DESCRIPTION`, :term:`LICENSE` or :term:`HOMEPAGE`
-  contain the expected information and should be set specifically for every
-  recipe.
-
-- In recipes, variables are also used to control build and runtime
-  dependencies between recipes/packages with other recipes/packages. The
-  most common should be: :term:`PROVIDES`, :term:`RPROVIDES`, :term:`DEPENDS`,
-  and :term:`RDEPENDS`.
-
-- There are further variables starting with ``SRC`` that specify the sources in
-  a recipe like :term:`SRC_URI` or :term:`SRCDATE`. Those are also usually set
-  in recipes.
-
-- Which version or provider of a recipe should be given preference when
-  multiple recipes would provide the same item, is controlled by variables
-  starting with ``PREFERRED_``. Those are normally set in the configuration
-  files of a ``MACHINE`` or ``DISTRO``.
