+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 = "") 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, patches against the various components
+should be sent to their respective upstreams.
+
+bitbake:
+    bitbake-devel@lists.openembedded.org
+
+meta-yocto:
+    poky@yoctoproject.org
+
+Most 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.
+    openembedded-core@lists.openembedded.org
+
+Note: The scripts directory should be treated with extra care as it is a mix
+      of oe-core and poky-specific files.

README.LSB

-OE-Core aims to be able to provide basic LSB compatible images. There
-are some challenges for OE as LSB isn't always 100% relevant to its
-target embedded and IoT audiences. 
-
-One challenge is that the LSB spec is no longer being actively
-developed [https://github.com/LinuxStandardBase/lsb] and has 
-components which are end of life or significantly dated. OE 
-therefore provides compatibility with the following caveats:
-
-* Qt4 is provided by the separate meta-qt4 layer. Its noted that Qt4 
-  is end of life and this isn't something the core project regularly 
-  tests any longer. Users are recommended to group together to support
-  maintenance of that layer. [http://git.yoctoproject.org/cgit/cgit.cgi/meta-qt4/]
-
-* mailx has been dropped since its no longer being developed upstream 
-  and there are better, more modern replacements such as s-nail 
-  (http://sdaoden.eu/code.html) or mailutils (http://mailutils.org/).
-
-* A few perl modules that were required by LSB 4.x aren't provided:
-  libclass-isa, libenv, libdumpvalue, libfile-checktree,
-  libi18n-collate, libpod-plainer.
-
-* libpng 1.2 isn't provided; oe-core includes the latest release of libpng

+                          Poky Hardware README
+                          ====================
+
+This file gives details about using Poky with different hardware reference
+boards and consumer devices. A full list of target machines can be found by
+looking in the meta/conf/machine/ directory. If in doubt about using Poky 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/community/documentation
+
+Support for machines other than QEMU may be moved out to separate BSP layers in
+future versions.
+
+
+QEMU Emulation Targets
+======================
+
+To simplify development Poky 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 Poky Reference Manual. The Poky
+MACHINE setting corresponding to the target is given in brackets.
+
+
+Hardware Reference Boards
+=========================
+
+The following boards are supported by Poky's core layer:
+
+  * Texas Instruments Beagleboard (beagleboard)
+  * Freescale MPC8315E-RDB (mpc8315e-rdb)
+  * Ubiquiti Networks RouterStation Pro (routerstationpro)
+
+For more information see the board's section below. The Poky MACHINE setting
+corresponding to the board is given in brackets.
+
+
+Consumer Devices
+================
+
+The following consumer devices are supported by Poky's core layer:
+
+  * Intel Atom based PCs and devices (atom-pc)
+
+For more information see the device's section below. The Poky MACHINE setting
+corresponding to the device is given in brackets.
+
+
+
+                      Specific Hardware Documentation
+                      ===============================
+
+
+Intel Atom based PCs and devices (atom-pc)
+==========================================
+
+The atom-pc MACHINE is tested on the following platforms:
+
+  o Asus EeePC 901
+  o Acer Aspire One
+  o Toshiba NB305
+  o Intel Embedded Development Board 1-N450 (Black Sand)
+
+and is likely to work on many unlisted Atom based devices. The MACHINE type
+supports ethernet, wifi, sound, and i915 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 poky 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 atom-pc 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-atom-pc.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. Without such an option, the BIOS generally boots the device in USB-ZIP
+     mode. To write an image to a USB device that will be bootable in
+     USB-ZIP mode, carry out the following actions:
+
+     a. Determine the geometry of your USB device using fdisk:
+
+     # fdisk /dev/sdb
+     Command (m for help): p
+
+     Disk /dev/sdb: 4011 MB, 4011491328 bytes
+     124 heads, 62 sectors/track, 1019 cylinders, total 7834944 sectors
+     ...
+
+     Command (m for help): q
+
+     b. Configure the USB device for USB-ZIP mode:
+     
+     # mkdiskimage -4 /dev/sdb 1019 124 62
+
+     Where 1019, 124 and 62 are the cylinder, head and sectors/track counts
+     as reported by fdisk (substitute the values reported for your device).
+     When the operation has finished and the access LED (if any) on the
+     device stops flashing, remove and reinsert the device to allow the
+     kernel to detect the new partition layout.
+
+     c. Copy the contents of the poky image to the USB-ZIP mode device:
+
+     # mkdir /tmp/image
+     # mkdir /tmp/usbkey
+     # mount -o loop core-image-minimal-atom-pc.hddimg  /tmp/image
+     # mount /dev/sdb4 /tmp/usbkey
+     # cp -rf /tmp/image/* /tmp/usbkey
+
+     d. Install the syslinux boot loader:
+
+     # syslinux /dev/sdb4
+
+     e. Unmount everything:
+
+     # umount /tmp/image
+     # umount /tmp/usbkey
+
+  Install the boot device in the target board and configure the BIOS to boot
+  from it.
+
+  For more details on the USB-ZIP scenario, see the syslinux documentation:
+  http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=blob_plain;f=doc/usbkey.txt;hb=HEAD
+
+
+Texas Instruments Beagleboard (beagleboard)
+===========================================
+
+The Beagleboard is an ARM Cortex-A8 development board with USB, DVI-D, S-Video,
+2D/3D accelerated graphics, audio, serial, JTAG, and SD/MMC. The xM adds a
+faster CPU, more RAM, an ethernet port, more USB ports, microSD, and removes
+the NAND flash. The beagleboard MACHINE is tested on the following platforms:
+
+  o Beagleboard C4
+  o Beagleboard xM rev A & B
+
+The Beagleboard C4 has NAND, while the xM does not. For the sake of simplicity,
+these instructions assume you have erased the NAND on the C4 so its boot
+behavior matches that of the xM. To do this, issue the following commands from
+the u-boot prompt (note that the unlock may be unecessary depending on the
+version of u-boot installed on your board and only one of the erase commands
+will succeed):
+
+    # nand unlock
+    # nand erase
+    # nand erase.chip
+
+To further tailor these instructions for your board, please refer to the
+documentation at http://www.beagleboard.org.
+
+From a Linux system with access to the image files perform the following steps
+as root, replacing mmcblk0* with the SD card device on your machine (such as sdc
+if used via a usb card reader):
+
+  1. Partition and format an SD card:
+     # fdisk -lu /dev/mmcblk0
+     
+     Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
+     255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
+     Units = sectors of 1 * 512 = 512 bytes
+     
+             Device Boot      Start         End      Blocks  Id System
+     /dev/mmcblk0p1   *          63      144584       72261   c Win95 FAT32 (LBA)
+     /dev/mmcblk0p2          144585      465884      160650  83 Linux
+
+     # mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
+     # mke2fs -j -L "root" /dev/mmcblk0p2
+
+  The following assumes the SD card partition 1 and 2 are mounted at
+  /media/boot and /media/root respectively. Removing the card and reinserting
+  it will do just that on most modern Linux desktop environments.
+  
+  The files referenced below are made available after the build in
+  build/tmp/deploy/images.
+
+  2. Install the boot loaders
+     # cp MLO-beagleboard /media/boot/MLO
+     # cp u-boot-beagleboard.bin /media/boot/u-boot.bin
+
+  3. Install the root filesystem
+     # tar x -C /media/root -f core-image-$IMAGE_TYPE-beagleboard.tar.bz2
+     # tar x -C /media/root -f modules-$KERNEL_VERSION-beagleboard.tgz
+
+  4. Install the kernel uImage
+     # cp uImage-beagleboard.bin /media/boot/uImage
+
+  5. Prepare a u-boot script to simplify the boot process
+     The Beagleboard can be made to boot at this point from the u-boot command
+     shell. To automate this process, generate a user.scr script as follows.
+
+     Install uboot-mkimage (from uboot-mkimage on Ubuntu or uboot-tools on Fedora).
+
+     Prepare a script config:
+
+     # (cat << EOF
+     setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
+     setenv bootargs 'console=tty0 console=ttyO2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro'
+     boot
+     EOF
+     ) > serial-boot.cmd
+     # mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Core Minimal" -d ./serial-boot.cmd ./boot.scr
+     # cp boot.scr /media/boot
+
+   6. Unmount the SD partitions, insert the SD card into the Beagleboard, and
+      boot the Beagleboard
+
+Note: As of the 2.6.37 linux-yocto kernel recipe, the Beagleboard uses the
+      OMAP_SERIAL device (ttyO2). If you are using an older kernel, such as the
+      2.6.34 linux-yocto-stable, be sure to replace ttyO2 with ttyS2 above. You
+      should also override the machine SERIAL_CONSOLE in your local.conf in
+      order to setup the getty on the serial line:
+
+      SERIAL_CONSOLE_beagleboard = "115200 ttyS2"
+
+
+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 Poky build 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 800000 uImage-mpc8315e-rdb.bin
+ => tftp 780000 uImage-mpc8315e-rdb.dtb
+ => bootm 800000 - 780000
+
+
+Ubiquiti Networks RouterStation Pro (routerstationpro)
+======================================================
+
+The RouterStation Pro is an Atheros AR7161 MIPS-based board. Geared towards
+networking applications, it has all of the usual features as well as three
+type IIIA mini-PCI slots and an on-board 3-port 10/100/1000 Ethernet switch,
+in addition to the 10/100/1000 Ethernet WAN port which supports
+Power-over-Ethernet.
+
+Setup instructions
+------------------
+
+You will need the following:
+* A serial cable - female to female (or female to male + gender changer)
+  NOTE: cable must be straight through, *not* a null modem cable.
+* USB flash drive or hard disk that is able to be powered from the
+  board's USB port.
+* tftp server installed on your workstation
+
+NOTE: in the following instructions it is assumed that /dev/sdb corresponds
+to the USB disk when it is plugged into your workstation. If this is not the
+case in your setup then please be careful to substitute the correct device
+name in all commands where appropriate.
+
+--- Preparation ---
+
+1) Build an image (e.g. core-image-minimal) using "routerstationpro" as the
+MACHINE
+
+2) Partition the USB drive so that primary partition 1 is type Linux (83).
+Minimum size depends on your root image size - core-image-minimal probably
+only needs 8-16MB, other images will need more.
+
+  # fdisk /dev/sdb
+  Command (m for help): p
+
+  Disk /dev/sdb: 4011 MB, 4011491328 bytes
+  124 heads, 62 sectors/track, 1019 cylinders, total 7834944 sectors
+  Units = sectors of 1 * 512 = 512 bytes
+  Sector size (logical/physical): 512 bytes / 512 bytes
+  I/O size (minimum/optimal): 512 bytes / 512 bytes
+  Disk identifier: 0x0009e87d
+
+     Device Boot      Start         End      Blocks   Id  System
+  /dev/sdb1              62     1952751      976345   83  Linux
+
+3) Format partition 1 on the USB as ext3
+
+  # mke2fs -j /dev/sdb1
+
+4) Mount partition 1 and then extract the contents of
+tmp/deploy/images/core-image-XXXX.tar.bz2 into it (preserving permissions).
+
+  # mount /dev/sdb1 /media/sdb1
+  # cd /media/sdb1
+  # tar -xvjpf tmp/deploy/images/core-image-XXXX.tar.bz2
+
+5) Unmount the USB drive and then plug it into the board's USB port
+
+6) Connect the board's 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
+
+7) Connect the network into eth0 (the one that is NOT the 3 port switch). If
+you are using power-over-ethernet then the board will power up at this point.
+
+8) Start up the board, watch the serial console. Hit Ctrl+C to abort the
+autostart if the board is configured that way (it is by default). The
+bootloader's fconfig command can be used to disable autostart and configure
+the IP settings if you need to change them (default IP is 192.168.1.20).
+
+9) Make the kernel (tmp/deploy/images/vmlinux-routerstationpro.bin) available
+on the tftp server.
+
+10) If you are going to write the kernel to flash (optional - see "Booting a
+kernel directly" below for the alternative), remove the current kernel and
+rootfs flash partitions. You can list the partitions using the following
+bootloader command:
+
+  RedBoot> fis list
+
+You can delete the existing kernel and rootfs with these commands:
+
+  RedBoot> fis delete kernel
+  RedBoot> fis delete rootfs
+
+--- Booting a kernel directly ---
+
+1) Load the kernel using the following bootloader command:
+
+  RedBoot> load -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin
+
+You should see a message on it being successfully loaded.
+
+2) Execute the kernel:
+
+  RedBoot> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"
+
+Note that specifying the command line with -c is important as linux-yocto does
+not provide a default command line.
+
+--- Writing a kernel to flash ---
+
+1) Go to your tftp server and gzip the kernel you want in flash. It should
+halve the size.
+
+2) Load the kernel using the following bootloader command:
+
+  RedBoot> load -r -b 0x80600000 -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin.gz
+
+This should output something similar to the following:
+
+  Raw file loaded 0x80600000-0x8087c537, assumed entry at 0x80600000
+
+Calculate the length by subtracting the first number from the second number
+and then rounding the result up to the nearest 0x1000.
+
+3) Using the length calculated above, create a flash partition for the kernel:
+
+  RedBoot> fis create -b 0x80600000 -l 0x240000 kernel
+
+(change 0x240000 to your rounded length -- change "kernel" to whatever
+you want to name your kernel)
+
+--- Booting a kernel from flash ---
+
+To boot the flashed kernel perform the following steps.
+
+1) At the bootloader prompt, load the kernel:
+
+  RedBoot> fis load -d -e kernel
+
+(Change the name "kernel" above if you chose something different earlier)
+
+(-e means 'elf', -d 'decompress')
+
+2) Execute the kernel using the exec command as above.
+
+--- Automating the boot process ---
+
+After writing the kernel to flash and testing the load and exec commands
+manually, you can automate the boot process with a boot script.
+
+1) RedBoot> fconfig
+   (Answer the questions not specified here as they pertain to your environment)
+2) Run script at boot: true
+  Boot script: 
+  .. fis load -d -e kernel
+  .. exec
+  Enter script, terminate with empty line

-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 in 32 and 64 bit variants:
-
-  * ARM (qemuarm + qemuarm64)
-  * x86 (qemux86 + qemux86-64)
-  * PowerPC (qemuppc only)
-  * MIPS (qemumips + qemumips64)
-
-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.

-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:
-    http://www.openembedded.org/
-
-Bitbake plain documentation can be found under the doc directory or its integrated
-html version at the Yocto Project website:
-    http://yoctoproject.org/documentation
-
-Contributing

-Please refer to
-http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
-for guidelines on how to submit patches, just note that the latter documentation is intended
-for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org)
-but in general main guidelines apply. Once the commit(s) have been created, the way to send
-the patch is through git-send-email. For example, to send the last commit (HEAD) on current

+Takes the specified layers (or all layers in the current layer

+containing the contents of all layers, with any overlayed recipes removed
+and bbappends appended to the corresponding recipes. Note that some manual

+* where non-recipe files (such as patches) are overwritten (the flatten
+  command will show a warning for these)
+* where anything beyond the normal layer setup has been added to
+  layer.conf (only the lowest priority number layer's layer.conf is used)
+* overridden/appended items from bbappends will need to be tidied up
+* when the flattened layers do not have the same directory structure (the
+  flatten command should show a warning when this will cause a problem)
+
+Warning: if you flatten several layers where another layer is intended to
+be used "inbetween" them (in layer priority order) such that recipes /
+bbappends in the layers interact, and then attempt to use the new output
+layer together with that other layer, you may no longer get the same

-This is the directory that contains the BitBake documentation. 
-
-Manual Organization
-===================
-
-Folders exist for individual manuals as follows:
-
-* bitbake-user-manual      - The BitBake User Manual 
-
-Each folder is self-contained regarding content and figures.
-
-If you want to find HTML versions of the BitBake manuals on the web, 
-go to http://www.openembedded.org/wiki/Documentation. 
-
-Makefile
-========
-
-The Makefile processes manual directories to create HTML, PDF,
-tarballs, etc.  Details on how the Makefile work are documented
-inside the Makefile.  See that file for more information.
-
-To build a manual, you run the make command and pass it the name
-of the folder containing the manual's contents. 
-For example, the following command run from the documentation directory 
-creates an HTML and a PDF version of the BitBake User Manual.
-The DOC variable specifies the manual you are making:
-
-     $ make DOC=bitbake-user-manual
-
-template
-========
-Contains various templates, fonts, and some old PNG files.
-
-tools
-=====
-Contains a tool to convert the DocBook files to PDF format.

-    <title>Execution</title>
-
-    <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.

-
-        <para>
-            The <filename>layer.conf</filename> files are used to

-            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.

-            The base configuration metadata is global

-            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,

-            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 <filename>base.bbclass</filename> file is always included.

-            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

-            A good way to get an idea of the configuration files and

-            run the following BitBake command:
-            <literallayout class='monospaced'>
-     $ bitbake -e > mybb.log
-            </literallayout>
-            Examining the top of the <filename>mybb.log</filename>

-                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>
-                Here is an example that causes BitBake to produce a parsing
-                error:
-                <literallayout class='monospaced'>
-     fakeroot create_shar() {
-         cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
-     usage()
-     {
-       echo "test"
-       ###### The following "}" at the start of the line causes a parsing error ######
-     }
-     EOF
-     }
-                </literallayout>
-                Writing the recipe this way avoids the error:
-                <literallayout class='monospaced'>
-     fakeroot create_shar() {
-         cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh

-        <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
-                <filename>BBFILES</filename>.
-            </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>:
-            <literallayout class='monospaced'>
-     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>
-
-        <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.

-            Recipe file collections exist to allow the user to
-            have multiple repositories of
-            <filename>.bb</filename> 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:
-            <literallayout class='monospaced'>
-    BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb"

-                The layers mechanism is now the preferred method of collecting

-                While the collections code remains, its main use is to set layer
-                priorities and to deal with overlap (conflicts) between layers.

-        <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>
-            variable, which is optional.
-        </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

-            The <filename>PROVIDES</filename> 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.
-        </para>
-
-        <para>
-            A common example in which a target has multiple providers
-            is "virtual/kernel", which is on the
-            <filename>PROVIDES</filename> list for each kernel recipe.
-            Each machine often selects the best kernel provider by using a

-            <literallayout class='monospaced'>
-     PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"

-            Bitbake iterates through each target it needs to build and

-        </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

-            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

-                It is common for a recipe to provide two versions -- a stable,

-
-        <para>
-            Each target BitBake builds consists of multiple tasks such as
-            <filename>fetch</filename>, <filename>unpack</filename>,
-            <filename>patch</filename>, <filename>configure</filename>,
-            and <filename>compile</filename>.
-            For best performance on multi-core systems, BitBake considers each
-            task as an independent
-            entity with its own set of dependencies.
-        </para>
-
-        <para>
-            Dependencies are defined through several variables.
-            You can find information about variables BitBake uses in
-            the <link linkend='ref-variables-glos'>Variables Glossary</link>
-            near the end of this manual.
-            At a basic level, it is sufficient to know that BitBake uses the
-            <link linkend='var-DEPENDS'><filename>DEPENDS</filename></link> and
-            <link linkend='var-RDEPENDS'><filename>RDEPENDS</filename></link> variables when
-            calculating dependencies.
-        </para>

-        <title>The Task List</title>
-
-        <para>
-            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
-            "<link linkend='executing-tasks'>Executing Tasks</link>" section has more
-            information on how BitBake chooses which task to execute next.
-        </para>
-
-        <para>
-            The build now starts with BitBake forking off threads up to the limit set in the
-            <link linkend='var-BB_NUMBER_THREADS'><filename>BB_NUMBER_THREADS</filename></link>
-            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.
-        </para>
-
-        <para>
-            It is worth noting that you can greatly speed up the build time by properly setting
-            the <filename>BB_NUMBER_THREADS</filename> variable.
-        </para>
-
-        <para>
-            As each task completes, a timestamp is written to the directory specified by the
-            <link linkend='var-STAMP'><filename>STAMP</filename></link> variable.
-            On subsequent runs, BitBake looks in the build directory within
-            <filename>tmp/stamps</filename> 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.
-        </para>
-
-        <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
-            the <filename>[stamp-extra-info]</filename> task flag.
-            For example, OpenEmbedded uses this flag to make some tasks machine-specific.
-        </para>
-
-        <note>
-            Some tasks are marked as "nostamp" tasks.
-            No timestamp file is created when these tasks are run.
-            Consequently, "nostamp" tasks are always rerun.

-
-        <para>
-            Tasks can be either a shell task or a Python task.
-            For shell tasks, BitBake writes a shell script to
-            <filename>${</filename><link linkend='var-T'><filename>T</filename></link><filename>}/run.do_taskname.pid</filename>
-            and then executes the script.
-            The generated shell script contains all the exported variables,
-            and the shell functions with all variables expanded.
-            Output from the shell script goes to the file
-            <filename>${T}/log.do_taskname.pid</filename>.
-            Looking at the expanded shell functions in the run file and
-            the output in the log files is a useful debugging technique.
-        </para>
-
-        <para>
-            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.
-        </para>
-
-        <para>
-            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

-        <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.

-            variable with a list of tasks and corresponding

-            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
-            to obtain the dependencies of that task.
-        </para>
-
-        <para>
-            Finally, after all the setscene tasks have executed, BitBake calls the
-            function listed in
-            <link linkend='var-BB_SETSCENE_VERIFY_FUNCTION2'><filename>BB_SETSCENE_VERIFY_FUNCTION2</filename></link>
-            with the list of tasks BitBake thinks has been "covered".
-            The metadata can then ensure that this list is correct and can
-            inform BitBake that it wants specific tasks to be run regardless
-            of the setscene result.

-    <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>

-        <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') 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')
-     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 \

-         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
-            as well as other things.

-        <title>The Unpack</title>
-
-        <para>
-            The unpack process usually immediately follows the download.
-            For all URLs except Git URLs, BitBake uses the common
-            <filename>unpack</filename> method.
-        </para>
-
-        <para>
-            A number of parameters exist that you can specify within the

-                <listitem><para><emphasis>unpack:</emphasis>
-                    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.

-
-        <para>
-            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.

-        <title>Fetchers</title>
-
-        <para>
-            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.

-                <filename>file://</filename>.
-                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
-                <link linkend='var-FILESPATH'><filename>FILESPATH</filename></link>
-                variable is used in the same way
-                <filename>PATH</filename> is used to find executables.
-                If the file cannot be found, it is assumed that it is available in

-            <para>
-                This fetcher obtains files from web and FTP servers.
-                Internally, the fetcher uses the wget utility.

-
-            <para>
-                The executable and parameters used are specified by the

-                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
-                <link linkend='var-DL_DIR'><filename>DL_DIR</filename></link>
-                when dealing with multiple files that have the same name.

-            </para>
-            <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"

-                This submodule handles checking out files from the
-                CVS version control system.
-                You can configure it using a number of different variables:
-                <itemizedlist>
-                    <listitem><para><emphasis><filename>FETCHCMD_cvs</filename>:</emphasis>
-                        The name of the executable to use when running
-                        the <filename>cvs</filename> command.
-                        This name is usually "cvs".

-                        The date to use when fetching the CVS source code.
-                        A special value of "now" causes the checkout to
-                        be updated on every build.

-                        Specifies where a temporary checkout is saved.
-                        The location is often <filename>DL_DIR/cvs</filename>.

-                As well as the standard username and password URL syntax,
-                you can also configure the fetcher with various URL parameters:
-            </para>
-
-            <para>
-                The supported parameters are as follows:
-                <itemizedlist>
-                    <listitem><para><emphasis>"method":</emphasis>
-                        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 <filename>CVS_RSH</filename>.
-                        You can use "dir" for local directories.

-                This fetcher submodule fetches code from the Git
-                source control system.
-                The fetcher works by creating a bare clone of the
-                remote into
-                <link linkend='var-GITDIR'><filename>GITDIR</filename></link>,
-                which is usually <filename>DL_DIR/git2</filename>.
-                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
-                <filename>FETCHCMD_git</filename>.
-            </para>

-                    <listitem><para><emphasis>"protocol":</emphasis>
-                        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".

-                        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.

-                        Only the raw Git metadata is provided.

-                        Specifies a tag to use for the checkout.
-                        To correctly resolve tags, BitBake must access the

-                        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.

-                        The "usehead" parameter implies no branch and only works

-                By default, the fetcher creates a configuration specification.
-                If you want this specification written to an area other than the default,
-                use the <filename>CCASE_CUSTOM_CONFIG_SPEC</filename> variable
-                in your recipe to define where the specification is written.
-                <note>
-                    the <filename>SRCREV</filename> loses its functionality if you
-                    specify this variable.
-                    However, <filename>SRCREV</filename> is still used to label the

-            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
-            </literallayout>
-            The console output tells you what version you are running.

-        <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.

-            command, which causes BitBake to fail and report problems.
-            The example progresses by adding pieces to the build to

-            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:
-            <link linkend='configuration-files'>Configuration Files</link>,
-            <link linkend='classes'>Classes</link>, and
-            <link linkend='recipes'>Recipes</link>.
-            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.

-                First, set up a directory for the "Hello World" project.

-     $ cd ~/hello

-                You can use this directory to keep all the metafiles needed
-                by BitBake.
-                Having a project directory is a good way to isolate your

-                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".

-                The configuration file needs to be in the <filename>conf</filename>
-                directory inside the layer.

-                Move to the <filename>conf</filename> directory and create a
-                <filename>layer.conf</filename> file that has the following:
-                <literallayout class='monospaced'>

-                    After the first execution, re-running

-                    using that same <filename>bitbake</filename> command,
-                    BitBake notices the stamp and therefore determines
-                    that the task does not need to be re-run.
-                    If you delete the <filename>tmp</filename> directory
-                    or run <filename>bitbake -c clean printhello</filename>
-                    and then re-run the build, the "Hello, World!" message will
-                    be printed again.

-        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.

-        <para>
-            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.

-        <title>History and Goals</title>
-
-        <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>BitBake, a generic task executor</para></listitem>
-                <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
-            <ulink url='http://www.yoctoproject.org'>Yocto Project</ulink>.
-        </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
-            embedded space, were scalable or maintainable.

-            Flexibility and power have always been the priorities.
-            BitBake is highly extensible and supports embedded Python code and

-
-        <para>
-            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".
-        </para>
-
-        <para>
-            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.

-        <para>
-            The remainder of this section introduces several concepts
-            that should be understood in order to better leverage
-            the power of BitBake.

-                BitBake Recipes, which are denoted by the file extension
-                <filename>.bb</filename>, are the most basic metadata files.
-                These recipe files provide BitBake with the following:

-                Within the context of BitBake, or any project utilizing BitBake
-                as its build system, files with the <filename>.bb</filename>
-                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, which are denoted by the

-            <para>
-                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.

-                Append files, which are files that have the
-                <filename>.bbappend</filename> file extension, extend or

-            </para>
-
-            <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>
-                Information in append files extends or

-            </para>
-
-            <para>
-                When you name an append file, you can use the
-                "<filename>%</filename>" 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.</filename><replaceable>x</replaceable><filename>.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>
-                <note><title>Important</title>
-                    The use of the "<filename>%</filename>" character
-                    is limited in that it only works directly in front of the
-                    <filename>.bbappend</filename> portion of the append file's
-                    name.
-                    You cannot use the wildcard character in any other
-                    location of the name.
-                </note>
-                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

-                             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.

-                             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

-       -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 or taskexp
-                             - default knotty).
-       --token=XMLRPCTOKEN   Specify the connection token to be used when

-                             (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.
-       --setscene-only       Only run setscene tasks, don't run any real tasks.

-                             automatically.
-       --runall=RUNALL       Run the specified task for any recipe in the taskgraph
-                             of the specified target (even if it wouldn't otherwise
-                             have run).
-       --runonly=RUNONLY     Run only the specified task within the taskgraph of
-                             the specified targets (and any task dependencies those

-                    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.

-                    Clearly there needs to be a way to tell BitBake what

-                    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

-                    By default, a recipe file generally "PROVIDES" its

-                    BitBake is able to generate dependency graphs using
-                    the <filename>dot</filename> syntax.
-                    You can convert these graphs into images using the

-
-                <para>
-                    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".
-                </para>
-
-                <para>
-                    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 <filename>conf</filename> named
-                    <filename>multiconfig</filename>.
-                    Following is an example for two separate targets:
-                    <imagedata fileref="figures/bb_multiconfig_files.png" align="center" width="4in" depth="3in" />

-
-                <para>
-                    The reason for this required file hierarchy
-                    is because the <filename>BBPATH</filename> 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.

-
-                <para>
-                    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.

-                <para>
-                    Aside from separate configuration files for each
-                    target, you must also enable BitBake to perform multiple
-                    configuration builds.
-                    Enabling is accomplished by setting the
-                    <link linkend='var-BBMULTICONFIG'><filename>BBMULTICONFIG</filename></link>
-                    variable in the <filename>local.conf</filename>
-                    configuration file.
-                    As an example, suppose you had configuration files
-                    for <filename>target1</filename> and
-                    <filename>target2</filename> defined in the build
-                    directory.
-                    The following statement in the
-                    <filename>local.conf</filename> file both enables
-                    BitBake to perform multiple configuration builds and
-                    specifies the two multiconfigs:
-                    <literallayout class='monospaced'>
-     BBMULTICONFIG = "target1 target2"
-                    </literallayout>
-                </para>
-
-                <para>
-                    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:
-                    <literallayout class='monospaced'>
-     $ bitbake [multiconfig:<replaceable>multiconfigname</replaceable>:]<replaceable>target</replaceable> [[[multiconfig:<replaceable>multiconfigname</replaceable>:]<replaceable>target</replaceable>] ... ]

-
-                <para>
-                    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.
-                </para>
-
-                <para>
-                    To enable dependencies in a multiple configuration
-                    build, you must declare the dependencies in the recipe
-                    using the following statement form:
-                    <literallayout class='monospaced'>
-     <replaceable>task_or_package</replaceable>[mcdepends] = "multiconfig:<replaceable>from_multiconfig</replaceable>:<replaceable>to_multiconfig</replaceable>:<replaceable>recipe_name</replaceable>:<replaceable>task_on_which_to_depend</replaceable>"
-                    </literallayout>
-                    To better show how to use this statement, consider an
-                    example with two multiconfigs: <filename>target1</filename>
-                    and <filename>target2</filename>:
-                    <literallayout class='monospaced'>
-     <replaceable>image_task</replaceable>[mcdepends] = "multiconfig:target1:target2:<replaceable>image2</replaceable>:<replaceable>rootfs_task</replaceable>"
-                    </literallayout>
-                    In this example, the
-                    <replaceable>from_multiconfig</replaceable> is "target1" and
-                    the <replaceable>to_multiconfig</replaceable> is "target2".
-                    The task on which the image whose recipe contains
-                    <replaceable>image_task</replaceable> depends on the
-                    completion of the <replaceable>rootfs_task</replaceable>
-                    used to build out <replaceable>image2</replaceable>, which
-                    is associated with the "target2" multiconfig.
-               </para>
-
-               <para>
-                   Once you set up this dependency, you can build the
-                   "target1" multiconfig using a BitBake command as follows:
-                   <literallayout class='monospaced'>
-     $ bitbake multiconfig:target1:<replaceable>image1</replaceable>
-                   </literallayout>
-                   This command executes all the tasks needed to create
-                   <replaceable>image1</replaceable> for the "target1"
-                   multiconfig.
-                   Because of the dependency, BitBake also executes through
-                   the <replaceable>rootfs_task</replaceable> for the "target2"
-                   multiconfig build.
-               </para>
-
-               <para>
-                   Having a recipe depend on the root filesystem of another
-                   build might not seem that useful.
-                   Consider this change to the statement in the
-                   <replaceable>image1</replaceable> recipe:
-                   <literallayout class='monospaced'>
-     <replaceable>image_task</replaceable>[mcdepends] = "multiconfig:target1:target2:<replaceable>image2</replaceable>:<replaceable>image_task</replaceable>"
-                   </literallayout>
-                   In this case, BitBake must create
-                   <replaceable>image2</replaceable> for the "target2"
-                   build since the "target1" build depends on it.
-               </para>
-
-               <para>
-                   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.

+        <title>Introduction</title>
+        <section>
+            <title>Overview</title>
+            <para>BitBake is, at its simplest, a tool for executing
+tasks and managing metadata.  As such, its similarities to GNU make and other
+build tools are readily apparent.  It was inspired by Portage, the package management system used by the Gentoo Linux distribution.  BitBake is the basis of the <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink> project, which is being used to build and maintain a number of embedded Linux distributions/projects such as Angstrom and the Yocto project.</para>
+        </section>
+        <section>
+            <title>Background and goals</title>
+            <para>Prior to BitBake, no other build tool adequately met
+the needs of an aspiring embedded Linux distribution.  All of the
+buildsystems used by traditional desktop Linux distributions lacked
+important functionality, and none of the ad-hoc
+<emphasis>buildroot</emphasis> systems, prevalent in the
+embedded space, were scalable or maintainable.</para>
+
+      <para>Some important original goals for BitBake were:
+            <itemizedlist>
+                <listitem><para>Handle crosscompilation.</para></listitem>
+                <listitem><para>Handle interpackage dependencies (build time on target architecture, build time on native architecture, and runtime).</para></listitem>
+                <listitem><para>Support running any number of tasks within a given package, including, but not limited to, fetching upstream sources, unpacking them, patching them, configuring them, et cetera.</para></listitem>
+                <listitem><para>Must be Linux distribution agnostic (both build and target).</para></listitem>
+                <listitem><para>Must be architecture agnostic</para></listitem>
+                <listitem><para>Must support multiple build and target operating systems (including Cygwin, the BSDs, etc).</para></listitem>
+                <listitem><para>Must be able to be self contained, rather than tightly integrated into the build machine's root filesystem.</para></listitem>
+                <listitem><para>There must be a way to handle conditional metadata (on target architecture, operating system, distribution, machine).</para></listitem>
+                <listitem><para>It must be easy for the person using the tools to supply their own local metadata and packages to operate against.</para></listitem>
+                <listitem><para>Must make it easy to collaborate
+between multiple projects using BitBake for their
+builds.</para></listitem>
+		<listitem><para>Should provide an inheritance mechanism to
+share common metadata between many packages.</para></listitem>
+            </itemizedlist>
+        </para>
+        <para>Over time it has become apparent that some further requirements were necessary:
+            <itemizedlist>
+                <listitem><para>Handle variants of a base recipe (native, sdk, multilib).</para></listitem>
+                <listitem><para>Able to split metadata into layers and allow layers to override each other.</para></listitem>
+                <listitem><para>Allow representation of a given set of input variables to a task as a checksum.</para></listitem>
+                <listitem><para>based on that checksum, allow acceleration of builds with prebuilt components.</para></listitem>
+            </itemizedlist>
+        </para>
+
+        <para>BitBake satisfies all the original requirements and many more with extensions being made to the basic functionality to reflect the additionl requirements.  Flexibility and power have always been the priorities.  It is highly extensible, supporting embedded Python code and execution of any arbitrary tasks.</para>

+        <title>Metadata</title>
+        <section>
+            <title>Description</title>
+            <itemizedlist>
+                <para>BitBake metadata can be classified into 3 major areas:</para>
+                <listitem>
+                    <para>Configuration Files</para>
+                </listitem>
+                <listitem>
+                    <para>.bb Files</para>
+                </listitem>
+                <listitem>
+                    <para>Classes</para>
+                </listitem>
+            </itemizedlist>
+            <para>What follows are a large number of examples of BitBake metadata.  Any syntax which isn't supported in any of the aforementioned areas will be documented as such.</para>
+            <section>
+                <title>Basic variable setting</title>
+                <para><screen><varname>VARIABLE</varname> = "value"</screen></para>
+                <para>In this example, <varname>VARIABLE</varname> is <literal>value</literal>.</para>
+            </section>
+            <section>

+                <para>BitBake supports variables referencing one another's contents using a syntax which is similar to shell scripting</para>

+<varname>B</varname> = "pre${A}post"</screen></para>
+                <para>This results in <varname>A</varname> containing <literal>aval</literal> and <varname>B</varname> containing <literal>preavalpost</literal>.</para>
+            </section>
+            <section>
+                <title>Setting a default value (?=)</title>
+                <para><screen><varname>A</varname> ?= "aval"</screen></para>
+                <para>If <varname>A</varname> is set before the above is called, it will retain its previous value. If <varname>A</varname> is unset prior to the above call, <varname>A</varname> will be set to <literal>aval</literal>.  Note that this assignment is immediate, so if there are multiple ?= assignments to a single variable, the first of those will be used.</para>
+            </section>
+            <section>
+                <title>Setting a weak default value (??=)</title>
+                <para><screen><varname>A</varname> ??= "somevalue"
+<varname>A</varname> ??= "someothervalue"</screen></para>
+                <para>If <varname>A</varname> is set before the above, it will retain that value.  If <varname>A</varname> is unset prior to the above, <varname>A</varname> will be set to <literal>someothervalue</literal>.  This is a lazy/weak assignment in that the assignment does not occur until the end of the parsing process, so that the last, rather than the first, ??= assignment to a given variable will be used. Any other setting of A using = or ?= will however override the value set with ??=</para>

+            <section>
+                <title>Immediate variable expansion (:=)</title>
+                <para>:= results in a variable's contents being expanded immediately, rather than when the variable is actually used.</para>

As an example, setting <screen>BBCLASSEXTEND = "native"</screen> results in a second incarnation of the current recipe being available.  This second incarnation will have the "native" class inherited.</para>
+                <para>The second feature is <varname>BBVERSIONS</varname>.  This variable allows a single recipe to build multiple versions of a project from a single recipe file, and allows you to specify conditional metadata (using the <varname>OVERRIDES</varname> mechanism) for a single version, or an optionally named range of versions:</para>
+                <para><screen>BBVERSIONS = "1.0 2.0 git"
+SRC_URI_git = "git://someurl/somepath.git"</screen></para>

+SRC_URI_append_1.0.7+ = "file://some_patch_which_the_new_versions_need.patch;patch=1"</screen></para>
+                <para>Note that the name of the range will default to the original version of the recipe, so given OE, a recipe file of foo_1.0.0+.bb will default the name of its versions to 1.0.0+.  This is useful, as the range name is not only placed into overrides; it's also made available for the metadata to use in the form of the <varname>BPV</varname> variable, for use in file:// search paths (<varname>FILESPATH</varname>).</para>

+
+            <para>The SRC_URI is normally used to tell BitBake which files to fetch. The next sections will describe the available fetchers and their options. Each fetcher honors a set of variables and per URI parameters separated by a <quote>;</quote> consisting of a key and a value. The semantics of the variables and parameters are defined by the fetcher. BitBake tries to have consistent semantics between the different fetchers.

+
+            <para>The overall fetch process is that first, fetches are attempted from PREMIRRORS. If those don't work, the original SRC_URI is attempted and if that fails, BitBake will fall back to MIRRORS. Cross urls are supported, so its possible to mirror a git repository on an http server as a tarball for example. Some example commonly used mirror definitions are:</para>

+                <para>bitbake is the primary command in the system.  It facilitates executing tasks in a single .bb file, or executing a given task on a set of multiple .bb files, accounting for interdependencies amongst them.</para>

+usage: bitbake [options] [package ...]
+
+Executes the specified task (default is 'build') for a given set of BitBake files.
+It expects that BBFILES is defined, which is a space separated list of files to
+be executed.  BBFILES does support wildcards.
+Default BBFILES are the .bb files in the current directory.
+
+options:
+  --version             show program's version number and exit
+  -h, --help            show this help message and exit
+  -b BUILDFILE, --buildfile=BUILDFILE
+                        execute the task against this .bb file, rather than a
+                        package from BBFILES.
+  -k, --continue        continue as much as possible after an error. While the
+                        target that failed, and those that depend on it,
+                        cannot be remade, the other dependencies of these
+                        targets can be processed all the same.
+  -f, --force           force run of specified cmd, regardless of stamp status
+  -i, --interactive     drop into the interactive mode also called the BitBake
+                        shell.
+  -c CMD, --cmd=CMD     Specify task to execute. Note that this only executes
+                        the specified task for the providee and the packages
+                        it depends on, i.e. 'compile' does not implicitly call
+                        stage for the dependencies (IOW: use only if you know
+                        what you are doing). Depending on the base.bbclass a
+                        listtasks task is defined and will show available
+                        tasks
+  -r FILE, --read=FILE  read the specified file before bitbake.conf
+  -v, --verbose         output more chit-chat to the terminal
+  -D, --debug           Increase the debug level. You can specify this more
+                        than once.
+  -n, --dry-run         don't execute, just go through the motions
+  -p, --parse-only      quit after parsing the BB files (developers only)
+  -s, --show-versions   show current and preferred versions of all packages
+  -e, --environment     show the global or per-package environment (this is
+                        what used to be bbread)
+  -g, --graphviz        emit the dependency trees of the specified packages in
+                        the dot syntax
+  -I IGNORED_DOT_DEPS, --ignore-deps=IGNORED_DOT_DEPS
+                        Stop processing at the given list of dependencies when
+                        generating dependency graphs. This can help to make
+                        the graph more appealing
+  -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
+                        Show debug logging for the specified logging domains
+  -P, --profile         profile the command and print a report

Clearly there needs to be a way to tell BitBake what files are available, and of those, which we want to execute at this time.  There also needs to be a way for each .bb to express its dependencies, both for build time and runtime.  There must be a way for the user to express their preferences when multiple .bb's provide the same functionality, or when there are multiple versions of a .bb.</para>

+Two files will be written into the current working directory, <emphasis>depends.dot</emphasis> containing dependency information at the package level and <emphasis>task-depends.dot</emphasis> containing a breakdown of the dependencies at the task level. To stop depending on common depends, one can use the <prompt>-I depend</prompt> to omit these from the graph. This can lead to more readable graphs.  This way, <varname>DEPENDS</varname> from inherited classes such as base.bbclass can be removed from the graph.</para>

-BitBake 'Fetch' clearcase implementation
-
-The clearcase fetcher is used to retrieve files from a ClearCase repository.
-
-Usage in the recipe:
-
-    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.
-
-Supported SRC_URI options are:
-
-- vob
-    (required) The name of the clearcase VOB (with prepending "/")
-
-- module
-    The module in the selected VOB (with prepending "/")
-
-    The module and vob parameters are combined to create
-    the following load rule in the view config spec:
-                load <vob><module>
-
-- proto
-    http or https
-
-Related variables:
-
-    CCASE_CUSTOM_CONFIG_SPEC
-            Write a config spec to this variable in your recipe to use it instead
-            of the default config spec generated by this fetcher.
-            Please note that the SRCREV loses its functionality if you specify
-            this variable. SRCREV is still used to label the archive after a fetch,
-            but it doesn't define what's fetched.
-
-User credentials:
-    cleartool:
-            The login of cleartool is handled by the system. No special steps needed.
-
-    rcleartool:
-            In order to use rcleartool with authenticated users an `rcleartool login` is
-            necessary before using the fetcher.

-BitBake 'Fetch' NPM implementation

-The NPM fetcher is used to retrieve files from the npmjs repository

-Usage in the recipe:
-
-    SRC_URI = "npm://registry.npmjs.org/;name=${PN};version=${PV}"
-    Suported SRC_URI options are:
-
-    - name
-    - version
-
-    npm://registry.npmjs.org/${PN}/-/${PN}-${PV}.tgz  would become npm://registry.npmjs.org;name=${PN};version=${PV}
-    The fetcher all triggers off the existence of ud.localpath. If that exists and has the ".done" stamp, its assumed the fetch is good/done

-BitBake SFTP Fetch implementation
-
-Class for fetching files via SFTP. It tries to adhere to the (now
-expired) IETF Internet Draft for "Uniform Resource Identifier (URI)
-Scheme for Secure File Transfer Protocol (SFTP) and Secure Shell
-(SSH)" (SECSH URI).
-
-It uses SFTP (as to adhere to the SECSH URI specification). It only
-supports key based authentication, not password. This class, unlike
-the SSH fetcher, does not support fetching a directory tree from the
-remote.

-  https://www.iana.org/assignments/uri-schemes/prov/sftp
-  https://tools.ietf.org/html/draft-ietf-secsh-filexfer-13
-
-Please note that '/' is used as host path seperator, and not ":"
-as you may be used to from the scp/sftp commands. You can use a
-~ (tilde) to specify a path relative to your home directory.
-(The /~user/ syntax, for specyfing a path relative to another
-user's home directory is not supported.) Note that the tilde must
-still follow the host path seperator ("/"). See exampels below.
-
-Example SRC_URIs:
-
-SRC_URI = "sftp://host.example.com/dir/path.file.txt"
-
-A path relative to your home directory.
-
-SRC_URI = "sftp://host.example.com/~/dir/path.file.txt"
-
-You can also specify a username (specyfing password in the
-URI is not supported, use SSH keys to authenticate):
-
-SRC_URI = "sftp://user@host.example.com/dir/path.file.txt"
