x11-common: Fix unusable serial console

The serial console port is basicly unusable in images containing X.
Login works fine, but at the shell prompt only one out of N input
characters (N usually between 2 and 10) gets through to the shell.

dbus-launch (running as "dbus-launch --sh-syntax --exit-with-session")
is also reading from /dev/console and "eating" the missing characters.

As soon as I stop the Xserver ("sh /etc/init.d/xserver-nodm stop")
the serial console starts wroking fine (because dbus-launch is not
running any more).

This patch addresses the problem.

+Name: Laverne
+Version: 4.0.1
+Built from Revision: fd7a07b3a2153826bedda2ef76b9a33ab2791680
+Build Date: Jan 26 2011
+Builder: autobuilder.pokylinux.org 
+
+The Laverne 4.0.1 Release ensures you can use Poky Laverne on systems running 
+Fedora 14 and Opensuse 11.3, fixes issues with the poky-qemu script, and fixes 
+several other bugs. For the full changelog for Laverne 4.0.1 please read 
+CHANGELOG.
+
+Following are descriptions of fixes and known issues.
+
+Fixes
+------------------------
+
+    * Make 3.82, as shipped with Fedora 14, included parser bug fixes that 
+    resulted in a much stricter parser. As a result, the Makefiles could not be 
+    parsed for many of the software versions shipped with Laverne. The Makefiles
+    in the following recipes were fixed:
+
+          o eglibc
+          o busybox
+          o procps
+          o linux-libc-headers
+          o gstreamer
+          o gst-plugins
+          o libowl-av
+          o owl-video-widget
+          o dates
+          o contacts
+          o web-webkit 
+
+    * The ability to build openssl-native on a system that has SELINUX enabled 
+    was restored. (We disabled the execstack flag at compile time.) 
+
+    * A host-intrusion issue caused by a failure in QEMU to find zlib headers 
+    during configure was fixed. The issue was causing qemu-native to use the 
+    system zlib if it was present. If the system zlib was not present the build 
+    would fail. 
+
+    * Stability and usability enhancements, which included handling relative 
+    filesystem paths, were made to poky-qemu scripts. 
+
+    * The run-time remapping of package names when adding extra packages to an 
+    image via the IMAGE_INSTALL mechanism were fixed. 
+
+    * The configure test in quilt for GNU patch was fixed to that it correctly 
+    detects the version. 
+
+Known Issues
+------------------------
+
+    * The mpc3815e-rbd and routerstationpro machines were untested and not a 
+    part of the official Laverne 4.0 release. These machines are still unusable 
+    for this Laverne 4.0.1 release.
+          o mpx3815e-rdb will not boot due to a kernel/uboot issue Bug #685
+          o routerstation will not boot (by default) due to incorrect boot 
+          parameters Bug #681
+          o routerstationpro debug messages related to the ethernet driver print 
+          during boot Bug #679 
+    * Shutdown/poweroff on qemuarm does not cleanly halt the virtual machine. 
+    To workaround this issue use the reboot command. Using this command avoids 
+    a "power-cycle" and instead cleanly shuts down the VM Bug #684
+    * Two "Connection Manager" icons appear in the Sato UI. This duplication has
+    been fixed in master. Note that you can use either icon to launch the 
+    connectivity UI. Bug #683
+    * The on-screen keyboard incorrectly launches in the qemumips machine. This 
+    issue is due to a mis-configured formfactor file Bug #682

-The poky repository master branch is no longer being updated.
+Poky
+====
 
-You can either:
+Poky platform builder is a combined cross build system and development 
+environment. It features support for building X11/Matchbox/GTK based 
+filesystem images for various embedded devices and boards. It also 
+supports cross-architecture application development using QEMU emulation
+and a standalone toolchain and SDK with IDE integration.
 
-a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs
-
-   https://docs.yoctoproject.org/dev-manual/poky-manual-setup.html
-
-b) use the new bitbake-setup
-
-   https://docs.yoctoproject.org/bitbake/bitbake-user-manual/bitbake-user-manual-environment-setup.html
-
-You can find more information in our documentation: https://docs.yoctoproject.org/
-
-Note that "poky" the distro setting is still available in meta-yocto as
-before and we continue to use and maintain that.
-
-Long live Poky!
-
-
-
-
-Some further information on the background of this change follows. The 
-details are taken from:
-https://lists.openembedded.org/g/openembedded-architecture/message/2179
-
-TLDR: People have complained about the combo-layer built poky
-repository for years. It was meant to be a temporary thing, we now have
-an alternative and I'm therefore doing what I promised I'd do. Change
-is tough, things may break but this is the right point to at least try
-it.
-
-I'd like to note that:
-  * setting up builds with a separate oe-core and bitbake clone 
-    works as it always has done
-  * you can change your CI just to use those two repos instead of poky
-  * bitbake-setup isn't mandatory, it will just be what the yocto-
-    docs presents to users
-  * we don't have to stop maintaining the poky repository 
-    however nobody will test the new approach/code unless we do
-  * we are optionally exposing sstate mirrors in the new config
-  * we are also exposing config fragments to users
-  * poky as a DISTRO in meta-yocto remains
-
-A bit more about the history and background for those who are
-interested and then some FAQs:
-
-Back around 2010 when we split up openembedded-classic and started
-developing layers, we made the artificial "poky" repository construct
-as a way to let people easily and quickly get started with the project.
-without cloning and managing multiple repositories. Layers were a new
-idea with lots of rough edges. kas didn't exist, I think repo was only
-just created and it was a different world. For us, it meant hacking up
-a quick tool, "combo-layer" and it was really a temporary solution to
-fill a gap and it was at least as functional as repo of the era. It was
-assumed we'd work it out properly in the future.
-
-At developer meetings there are inevitable questions about why
-poky/combo-layer exist and few seem to actually like/support it. There
-are continual questions about why a tool doesn't exist or why we don't
-adopt one too.
-
-15 years later, a bit longer than we might have thought, we are finally
-in a position where there may be a viable way forward to change.
-
-It has taken us a bit of time to get to this point. I wrote the
-original description of something like bitbake-setup about 7-8 years
-ago. I shared it privately with a few people, the review feedback
-stopped me pushing it further as I simply did not have the bandwidth.
-We were fortunate to get funding from the Sovereign Tech Fund to start
-the work and whilst I'd probably prefer to avoid the issue, the time
-had come to start. Since then, Alexander Kanavin has put a lot of work
-into getting it to the point where it would be possible to switch. A
-huge thanks to him for getting this to the current point.
-
-Why not use kas/submodules/repo?
-
-This topic has been discussed in depth several times. Very roughly,
-these are either difficult to focus on our use cases or have specific
-designs and intent which we as a project would struggle to influence.
-We are taking significant influence from some of them but also trying
-to build something where we can benefit from tight direct integration
-with bitbake and the metadata. For example fragment support is generic
-and hopefully something other approaches can also benefit from. We want
-to provide something we can switch the projects docs and autobuilder to
-which we can control and develop as we need it to. We are not aiming to
-force anyone to switch, you can use whichever tool you want.
-
-Can we not keep poky [repository master branch] around?
-
-If we do that, nobody will use the new tooling and it will be a
-disaster as issues won't get resolved. We need our CI to use the same
-thing we promote to our new and experienced users. We need this new
-tooling to be usable by our experienced developers too. We have tried
-for months to get people to try it and they simply don't. Making a
-release with it won't change much either. It needs people using it and
-for that, poky has to stop being updated.
-
-What happens to poky [repository]?
-
-The LTS branches continue their lifetime as planned. For master, I'll
-probably put a final commit in changing to just a README which points
-people at the bitbake-setup changes and explains what happened.
-
-What are the timelines? Why now?
-
-If we're going to make a change, we really want this in the next LTS
-release, which is April 2026. We only have one release before that
-which is now, October 2025. We therefore need to switch now, and then
-give us time to update docs, fix issues that arise and so on and have
-it in a release cycle. Whilst it means delaying the Oct 2025 release
-slightly, that is the right thing to do in the context of the bigger
-picture.

+                          =========================
+
+Compulab CM-X270 (cm-x270)
+==========================
+
+The bootloader on this board doesn't support writing jffs2 images directly to 
+NAND and normally uses a proprietary kernel flash driver. To allow the use of
+jffs2 images, a two stage updating procedure is needed. Firstly, an initramfs
+is booted which contains mtd utilities and this is then used to write the main
+filesystem. 
+
+It is assumed the board is connected to a network where a TFTP server is 
+available and that a serial terminal is available to communicate with the 
+bootloader (38400, 8N1). If a DHCP server is available the device will use it
+to obtain an IP address. If not, run:
+
+  ARMmon > setip dhcp off
+  ARMmon > setip ip 192.168.1.203
+  ARMmon > setip mask 255.255.255.0
+
+To reflash the kernel:
+
+  ARMmon > download kernel tftp zimage 192.168.1.202
+  ARMmon > flash kernel
+
+where zimage is the name of the kernel on the TFTP server and its IP address is 
+192.168.1.202. The names of the files must be all lowercase.
+
+To reflash the initrd/initramfs:
+
+  ARMmon > download ramdisk tftp diskimage 192.168.1.202
+  ARMmon > flash ramdisk
+
+where diskimage is the name of the initramfs image (a cpio.gz file).
+
+To boot the initramfs:
+
+  ARMmon > ramdisk on
+  ARMmon > bootos "console=ttyS0,38400 rdinit=/sbin/init"
+
+To reflash the main image login to the system as user "root", then run:
+
+  # ifconfig eth0 192.168.1.203
+  # tftp -g -r mainimage 192.168.1.202
+  # flash_eraseall /dev/mtd1
+  # nandwrite /dev/mtd1 mainimage
+
+which configures the network interface with the IP address 192.168.1.203,
+downloads the "mainimage" file from the TFTP server at 192.168.1.202, erases
+the flash and then writes the new image to the flash.
+
+The main image can then be booted with:
+
+  ARMmon > bootos "console=ttyS0,38400 root=/dev/mtdblock1 rootfstype=jffs2"
+
+Note that the initramfs image is built by poky in a slightly different mode to
+normal since it uses uclibc. To generate this use a command like:
+
+IMAGE_FSTYPES=cpio.gz MACHINE=cm-x270 POKYLIBC=uclibc bitbake poky-image-minimal-mtdutils
+
+
+Compulab EM-X270 (em-x270)
+==========================
+
+Fetch the "Linux - kernel and run-time image (Angstrom)" ZIP file from the
+Compulab website. Inside the images directory of this ZIP file is another ZIP
+file called 'LiveDisk.zip'. Extract this over a cleanly formatted vfat USB flash
+drive. Replace the 'em_x270.img' file with the 'updater-em-x270.ext2' file.
+
+Insert this USB disk into the supplied adapter and connect this to the
+board. Whilst holding down the the suspend button press the reset button. The
+board will now boot off the USB key and into a version of Angstrom. On the
+desktop is an icon labelled "Updater". Run this program to launch the updater
+that will flash the Poky kernel and rootfs to the board.
+
+
+FreeScale iMX31ADS (mx31ads)
+===========================
+
+The correct serial port is the top-most female connector to the right of the
+ethernet socket.
+
+For uploading data to RedBoot we are going to use tftp. In this example we
+assume that the tftpserver is on 192.168.9.1 and the board is on192.168.9.2. 
+
+To set the IP address, run:
+
+  ip_address -l 192.168.9.2/24 -h 192.168.9.1
+
+To download a kernel called "zimage" from the TFTP server, run:
+
+  load -r -b 0x100000 zimage
+
+To write the kernel to flash run:
+
+  fis create kernel
+
+To download a rootfs jffs2 image "rootfs" from the TFTP server, run:
+
+  load -r -b 0x100000 rootfs
+
+To write the root filesystem  to flash run:
+
+  fis create root
+
+To load and boot a kernel and rootfs from flash:
+
+  fis load kernel
+  exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock2 rootfstype=jffs2 init=linuxrc ip=none"
+
+To load and boot a kernel from a TFTP server with the rootfs over NFS:
+
+  load -r -b 0x100000 zimage
+  exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200 root=/dev/nfs nfsroot=192.168.9.1:/mnt/nfsmx31 rw ip=192.168.9.2::192.168.9.1:255.255.255.0"
+
+The instructions above are for using the (default) NOR flash on the board,
+there is also 128M of NAND flash. It is possible to install Poky to the NAND 
+flash which gives more space for the rootfs and instructions for using this are
+given below. To switch to the NAND flash:
+
+  factive NAND
+
+This will then restart RedBoot using the NAND rather than the NOR. If you
+have not used the NAND before then it is unlikely that there will be a
+partition table yet. You can get the list of partitions with 'fis list'.
+
+If this shows no partitions then you can create them with:
+
+  fis init
+
+The output of 'fis list' should now show:
+
+Name              FLASH addr  Mem addr    Length      Entry point
+RedBoot           0xE0000000  0xE0000000  0x00040000  0x00000000
+FIS directory     0xE7FF4000  0xE7FF4000  0x00003000  0x00000000
+RedBoot config    0xE7FF7000  0xE7FF7000  0x00001000  0x00000000
+
+Partitions for the kernel and rootfs need to be created:
+
+fis create -l 0x1A0000 -e 0x00100000 kernel
+fis create -l 0x5000000 -e 0x00100000 root
+
+You may now use the instructions above for flashing. However it is important
+to note that the erase block size for the NAND is different to the NOR so the
+JFFS erase size will need to be changed to 0x4000. Stardard images are built
+for NOR and you will need to build custom images for NAND.
+
+You will also need to update the kernel command line to use the correct root
+filesystem. This should be '/dev/mtdblock7' if you adhere to the partitioning
+scheme shown above. If this fails then you can doublecheck against the output
+from the kernel when it evaluates the available mtd partitions.
+
+
+Marvell PXA3xx Zylonite (zylonite)
+==================================
+
+These instructions assume the Zylonite is connected to a machine running a TFTP 
+server at address 192.168.123.5 and that a serial link (38400 8N1) is available 
+to access the blob bootloader. The kernel is on the TFTP server as 
+"zylonite-kernel" and the root filesystem jffs2 file is "zylonite-rootfs" and 
+the images are to be saved in NAND flash.
+
+The following commands setup blob:
+
+  blob> setip client 192.168.123.4
+  blob> setip server 192.168.123.5
+
+To flash the kernel:
+
+  blob> tftp zylonite-kernel
+  blob> nandwrite -j 0x80800000 0x60000 0x200000
+
+To flash the rootfs:
+
+  blob> tftp zylonite-rootfs
+  blob> nanderase -j 0x260000 0x5000000
+  blob> nandwrite -j 0x80800000 0x260000 <length>
+
+(where <length> is the rootfs size which will be printed by the tftp step)
+
+To boot the board:
+
+  blob> nkernel
+  blob> boot
+
+
+Logic iMX31 Lite Kit (mx31litekit)
+===============================
+
+The easiest method to boot this board is to take an MMC/SD card and format 
+the first partition as ext2, then extract the poky image onto this as root. 
+Assuming the board is network connected, a TFTP server is available at 
+192.168.1.33 and a serial terminal is available (115200 8N1), the following 
+commands will boot a kernel called "mx31kern" from the TFTP server:
+
+  losh> ifconfig sm0 192.168.1.203 255.255.255.0 192.168.1.33
+  losh> load raw 0x80100000 0x200000 /tftp/192.168.1.33:mx31kern
+  losh> exec 0x80100000 - 
+
+
+Phytec phyCORE-iMX31 (mx31phy)
+==============================
+
+Support for this board is currently being developed. Experimental jffs2 
+images and a suitable kernel are available and are known to work with the
+board.
+
+
+                             Consumer Devices
+                             ================
+
+FIC Neo1973 GTA01 smartphone (fic-gta01)
+========================================
+
+To install Poky on a GTA01 smartphone you will need "dfu-util" tool
+which you can build with "bitbake dfu-util-native" command.
+
+Flashing requires these steps:
+
+  1. Power down the device.
+  2. Connect the device to the host machine via USB.
+  3. Hold AUX key and press Power key. There should be a bootmenu
+     on screen.
+  4. Run "dfu-util -l" to check if the phone is visible on the USB bus. 
+     The output should look like this:
+
+     dfu-util - (C) 2007 by OpenMoko Inc.
+     This program is Free Software and has ABSOLUTELY NO WARRANTY
+
+     Found Runtime: [0x1457:0x5119] devnum=19, cfg=0, intf=2, alt=0, name="USB Device Firmware Upgrade"
+
+  5. Flash the kernel with "dfu-util -a kernel -D uImage-2.6.21.6-moko11-r2-fic-gta01.bin"
+  6. Flash rootfs with "dfu-util -a rootfs -D <image>", where <image> is the
+     jffs2 image file to use as the root filesystem 
+     (e.g. ./tmp/deploy/images/poky-image-sato-fic-gta01.jffs2) 
+
+
+HTC Universal (htcuniversal)
+============================
+
+Note: HTC Universal support is highly experimental.
+
+On the HTC Universal, entirely replacing the Windows installation is not 
+supported, instead Poky is booted from an MMC/SD card from Windows. Once Poky
+has booted, Windows is no longer in memory or active but when power is removed,
+the user will be returned to windows and will need to return to Linux from 
+there.
+
+Once an MMC/SD card is available it is suggested its split into two partitions,
+one for a program called HaRET which lets you boot Linux from within Windows
+and the second for the rootfs. The HaRET partition should be the first partition
+on the card and be vfat formatted. It doesn't need to be large, just enough for
+HaRET and a kernel (say 5MB max). The rootfs should be ext2 and is usually the 
+second partition. The first partition should be vfat so Windows recognises it 
+as if it doesn't, it has been known to reformat cards.
+
+On the first partition you need three files:
+
+  * a HaRET binary (version 0.5.1 works well and a working version 
+    should be part of the last Poky release)
+  * a kernel renamed to "zImage"
+  * a default.txt which contains:
+
+set kernel "zImage"
+set mtype "855"
+set cmdline "root=/dev/mmcblk0p2 rw console=ttyS0,115200n8 console=tty0 rootdelay=5 fbcon=rotate:1"
+boot2
+
+On the second parition the root file system is extracted as root. A different
+partition layout or other kernel options can be changed in the default.txt file.
+
+When inserted into the device, Windows should see the card and let you browse
+its contents using File Explorer. Running the HaRET binary will present a dialog
+box (maybe after messages warning about running unsigned binaries) where you 
+select OK and you should then see Poky boot. Kernel messages can be seen by 
+adding psplash=false to the kernel commandline.
+
+
+Nokia 770/N800/N810 Internet Tablets (nokia770 and nokia800)
+============================================================
+
+Note: Nokia tablet support is highly experimental.
+
+The Nokia internet tablet devices are OMAP based tablet formfactor devices 
+with large screens (800x480), wifi and touchscreen.
+
+To flash images to these devices you need the "flasher" utility which can be 
+downloaded from the http://tablets-dev.nokia.com/d3.php?f=flasher-3.0. This 
+utility needs to be run as root and the usb filesystem needs to be mounted 
+although most distributions will have done this for you. Once you have this 
+follow these steps:
+
+  1. Power down the device.
+  2. Connect the device to the host machine via USB 
+     (connecting power to the device doesn't hurt either).
+  3. Run "flasher -i"
+  4. Power on the device.
+  5. The program should give an indication it's found 
+     a tablet device. If not, recheck the cables, make sure you're 
+     root and usbfs/usbdevfs is mounted.
+  6. Run "flasher -r <image> -k <kernel> -f", where <image> is the
+     jffs2 image file to use as the root filesystem 
+     (e.g. ./tmp/deploy/images/poky-image-sato-nokia800.jffs2) 
+     and <kernel> is the kernel to use 
+     (e.g. ./tmp/deploy/images/zImage-nokia800.bin).
+  7. Run "flasher -R" to reboot the device.
+  8. The device should boot into Poky.
+
+The nokia800 images and kernel will run on both the N800 and N810.
+
+
+Sharp Zaurus SL-C7x0 series (c7x0)
+==================================
+
+The Sharp Zaurus c7x0 series (SL-C700, SL-C750, SL-C760, SL-C860, SL-7500)
+are PXA25x based handheld PDAs with VGA screens. To install Poky images on
+these devices follow these steps:
+
+  1. Obtain an SD/MMC or CF card with a vfat or ext2 filesystem.
+  2. Copy a jffs2 image file (e.g. poky-image-sato-c7x0.jffs2) onto the
+     card as "initrd.bin":
+
+     $ cp ./tmp/deploy/images/poky-image-sato-c7x0.jffs2 /path/to/my-cf-card/initrd.bin
+
+  3. Copy an Linux kernel file (zImage-c7x0.bin) onto the card as 
+     "zImage.bin":
+
+     $ cp ./tmp/deploy/images/zImage-c7x0.bin /path/to/my-cf-card/zImage.bin
+
+  4. Copy an updater script (updater.sh.c7x0) onto the card
+     as "updater.sh":
+
+     $ cp ./tmp/deploy/images/updater.sh.c7x0 /path/to/my-cf-card/updater.sh
+
+  5. Power down the Zaurus.
+  6. Hold "OK" key and power on the device. An update menu should appear 
+     (in Japanese).
+  7. Choose "Update" (item 4).
+  8. The next screen will ask for the source, choose the appropriate 
+     card (CF or SD).
+  9. Make sure AC power is connected.
+  10. The next screen asks for confirmation, choose "Yes" (the left button).
+  11. The update process will start, flash the files on the card onto 
+      the device and the device will then reboot into Poky.
+
+
+Sharp Zaurus SL-C1000 (akita)
+=============================
+
+The Sharp Zaurus SL-C1000 is a PXA270 based device otherwise similar to the 
+c7x0. To install Poky images on this device follow the instructions for 
+the c7x0 but replace "c7x0" with "akita" where appropriate.
+
+
+Sharp Zaurus SL-C3x00 series (spitz)
+====================================
+
+The Sharp Zaurus SL-C3x00 devices are PXA270 based devices similar
+to akita but with an internal microdrive. The installation procedure 
+assumes a standard microdrive based device where the root (first) 
+partition has been enlarged to fit the image (at least 100MB, 
+400MB for the SDK).
+
+The procedure is the same as for the c7x0 and akita models with the 
+following differences:
+
+ 1. Instead of a jffs2 image you need to copy a compressed tarball of the 
+    root fileystem (e.g. poky-image-sato-spitz.tar.gz) onto the
+    card as "hdimage1.tgz":
+
+    $ cp ./tmp/deploy/images/poky-image-sato-spitz.tar.gz /path/to/my-cf-card/hdimage1.tgz
+
+ 2. You additionally need to copy a special tar utility  (gnu-tar) onto 
+    the card as "gnu-tar":
+
+    $ cp ./tmp/deploy/images/gnu-tar /path/to/my-cf-card/gnu-tar
+
+
+

+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+	- No longer weight providers on the basis of a package being "already staged". This
+	  leads to builds being non-deterministic.
+	- Flush stdout/stderr before forking to fix duplicate console output
+	- Make sure recrdeps tasks include all inter-task dependencies of a given fn
+	- Add bb.runqueue.check_stamp_fn() for use by packaged-staging

+	  directory != the cache dir.
+	- Add md5 and sha256 checksum generation functions to utils.py
+	- Correctly handle '-' characters in class names (#2958)
+	- Make sure expandKeys has been called on the data dictionary before running tasks

+	- Revert the '-' character fix in class names since it breaks things
+	- When a regexp fails to compile for PACKAGES_DYNAMIC, print a more useful error (#4444)
+	- Allow to checkout CVS by Date and Time. Just add HHmm to the SRCDATE.
+	- Move prunedir function to utils.py and add explode_dep_versions function
+	- Raise an exception if SRCREV == 'INVALID'
+	- Fix hg fetcher username/password handling and fix crash
+	- Fix PACKAGES_DYNAMIC handling of packages with '++' in the name
+	- Rename __depends to __base_depends after configuration parsing so we don't
+	  recheck the validity of the config files time after time
+	- Add better environmental variable handling. By default it will now only pass certain 
+	  whitelisted variables into the data store. If BB_PRESERVE_ENV is set bitbake will use
+	  all variable from the environment. If BB_ENV_WHITELIST is set, that whitelist will be
+	  used instead of the internal bitbake one. Alternatively, BB_ENV_EXTRAWHITE can be used
+	  to extend the internal whitelist.
+	- Perforce fetcher fix to use commandline options instead of being overriden by the environment
+	- bb.utils.prunedir can cope with symlinks to directoriees without exceptions
+	- use @rev when doing a svn checkout
+	- Add osc fetcher (from Joshua Lock in Poky)
+	- When SRCREV autorevisioning for a recipe is in use, don't cache the recipe
+	- Add tryaltconfigs option to control whether bitbake trys using alternative providers
+	  to fulfil failed dependencies. It defaults to off, changing the default since this
+	  behaviour confuses many users and isn't often useful.
+	- Improve lock file function error handling
+	- Add username handling to the git fetcher (Robert Bragg)
+	- Add support for HTTP_PROXY and HTTP_PROXY_IGNORE variables to the wget fetcher
+	- Export more variables to the fetcher commands to allow ssh checkouts and checkouts through 
+	  proxies to work better. (from Poky)
+	- Also allow user and pswd options in SRC_URIs globally (from Poky)
+	- Improve proxy handling when using mirrors (from Poky)
+	- Add bb.utils.prune_suffix function
+	- Fix hg checkouts of specific revisions (from Poky)
+	- Fix wget fetching of urls with parameters specified (from Poky)
+	- Add username handling to git fetcher (from Poky)
+	- Set HOME environmental variable when running fetcher commands (from Poky)
+	- Make sure allowed variables inherited from the environment are exported again (from Poky)
+	- When running a stage task in bbshell, run populate_staging, not the stage task (from Poky)
+	- Fix + character escaping from PACKAGES_DYNAMIC (thanks Otavio Salvador)
+	- Addition of BBCLASSEXTEND support for allowing one recipe to provide multiple targets (from Poky)
+

+	- Release 1.7.x as a stable series
+
+Changes in BitBake 1.7.x:
+	- Major updates of the dependency handling and execution

+	  storage
+
+Changes in BitBake 1.2.1:
+	The 1.2.1 release is meant as a intermediate release to lay the
+	ground for more radical changes. The most notable changes are:
+
+	- Do not hardcode {}, use bb.data.init() instead if you want to
+	  get a instance of a data class
+	- bb.data.init() is a factory and the old bb.data methods are delegates
+	- Do not use deepcopy use bb.data.createCopy() instead.
+	- Removed default arguments in bb.fetch

+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+.SH NAME
+BitBake \- simple tool for the execution of tasks
+.SH SYNOPSIS
+.B bitbake
+.RI [ options ] " packagenames"
+.br
+.SH DESCRIPTION
+This manual page documents briefly the
+.B bitbake
+command.
+.PP
+.\" TeX users may be more comfortable with the \fB<whatever>\fP and
+.\" \fI<whatever>\fP escape sequences to invode bold face and italics, 
+.\" respectively.
+\fBbitbake\fP is a program that executes the specified task (default is 'build')
+for a given set of BitBake files.
+.br
+It expects that BBFILES is defined, which is a space separated list of files to
+be executed. BBFILES does support wildcards.
+.br
+Default BBFILES are the .bb files in the current directory.
+.SH OPTIONS
+This program follow the usual GNU command line syntax, with long
+options starting with two dashes (`-').
+.TP
+.B \-h, \-\-help
+Show summary of options.
+.TP
+.B \-\-version
+Show version of program.
+.TP
+.B \-bBUILDFILE, \-\-buildfile=BUILDFILE
+execute the task against this .bb file, rather than a package from BBFILES.
+.TP
+.B \-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.
+.TP
+.B \-a, \-\-tryaltconfigs
+continue with builds by trying to use alternative providers where possible.
+.TP
+.B \-f, \-\-force
+force run of specified cmd, regardless of stamp status
+.TP
+.B \-i, \-\-interactive
+drop into the interactive mode also called the BitBake shell.
+.TP
+.B \-cCMD, \-\-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.
+.TP
+.B \-rFILE, \-\-read=FILE 
+read the specified file before bitbake.conf
+.TP
+.B \-v, \-\-verbose
+output more chit-chat to the terminal
+.TP
+.B \-D, \-\-debug
+Increase the debug level. You can specify this more than once.
+.TP
+.B \-n, \-\-dry-run
+don't execute, just go through the motions
+.TP
+.B \-p, \-\-parse-only
+quit after parsing the BB files (developers only)
+.TP
+.B \-d, \-\-disable-psyco
+disable using the psyco just-in-time compiler (not recommended)
+.TP
+.B \-s, \-\-show-versions
+show current and preferred versions of all packages
+.TP
+.B \-e, \-\-environment
+show the global or per-package environment (this is what used to be bbread)
+.TP
+.B \-g, \-\-graphviz
+emit the dependency trees of the specified packages in the dot syntax
+.TP
+.B \-IIGNORED\_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
+.TP
+.B \-lDEBUG_DOMAINS, \-\-log-domains=DEBUG_DOMAINS
+Show debug logging for the specified logging domains
+.TP
+.B \-P, \-\-profile
+profile the command and print a report
+.TP
+

+        <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, including OpenZaurus and Familiar.</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 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>
+                <listitem><para>Et cetera...</para></listitem>
+            </itemizedlist>
+        </para>
+        <para>BitBake satisfies all these and many more.  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>
+                <title>Variable expansion</title>
+                <para>BitBake supports variables referencing one another's contents using a syntax which is similar to shell scripting</para>
+                <para><screen><varname>A</varname> = "aval"
+<varname>B</varname> = "pre${A}post"</screen></para>
+                <para>This results in <varname>A</varname> containing <literal>aval</literal> and <varname>B</varname> containing <literal>preavalpost</literal>.</para>
+            </section>
+            <section>
+                <title>Setting a default value (?=)</title>
+                <para><screen><varname>A</varname> ?= "aval"</screen></para>
+                <para>If <varname>A</varname> is set before the above is called, it will retain it's previous value. If <varname>A</varname> is unset prior to the above call, <varname>A</varname> will be set to <literal>aval</literal>.  Note that this assignment is immediate, so if there are multiple ?= assignments to a single variable, the first of those will be used.</para>
+            </section>
+            <section>
+                <title>Setting a default value (??=)</title>
+                <para><screen><varname>A</varname> ??= "somevalue"</screen></para>
+                <para><screen><varname>A</varname> ??= "someothervalue"</screen></para>
+                <para>If <varname>A</varname> is set before the above, it will retain that value.  If <varname>A</varname> is unset prior to the above, <varname>A</varname> will be set to <literal>someothervalue</literal>.  This is a lazy version of ??=, in that the assignment does not occur until the end of the parsing process, so that the last, rather than the first, ??= assignment to a given variable will be used.</para>
+            </section>
+            <section>
+                <title>Immediate variable expansion (:=)</title>
+                <para>:= results in a variable's contents being expanded immediately, rather than when the variable is actually used.</para>
+                <para><screen><varname>T</varname> = "123"
+<varname>A</varname> := "${B} ${A} test ${T}"
+<varname>T</varname> = "456"
+<varname>B</varname> = "${T} bval"
+
+<varname>C</varname> = "cval"
+<varname>C</varname> := "${C}append"</screen></para>
+                <para>In that example, <varname>A</varname> would contain <literal> test 123</literal>, <varname>B</varname> would contain <literal>456 bval</literal>, and <varname>C</varname> would be <literal>cvalappend</literal>.</para>
+            </section>
+            <section>
+                <title>Appending (+=) and prepending (=+)</title>
+                <para><screen><varname>B</varname> = "bval"
+<varname>B</varname> += "additionaldata"
+<varname>C</varname> = "cval"
+<varname>C</varname> =+ "test"</screen></para>
+                <para>In this example, <varname>B</varname> is now <literal>bval additionaldata</literal> and <varname>C</varname> is <literal>test cval</literal>.</para>
+            </section>
+            <section>
+                <title>Appending (.=) and prepending (=.) without spaces</title>
+                    <para><screen><varname>B</varname> = "bval"
+<varname>B</varname> .= "additionaldata"
+<varname>C</varname> = "cval"
+<varname>C</varname> =. "test"</screen></para>
+                <para>In this example, <varname>B</varname> is now <literal>bvaladditionaldata</literal> and <varname>C</varname> is <literal>testcval</literal>. In contrast to the above Appending and Prepending operators no additional space
+will be introduced.</para>
+            </section>
+            <section>
+                <title>Conditional metadata set</title>
+                <para>OVERRIDES is a <quote>:</quote> separated variable containing each item you want to satisfy conditions.  So, if you have a variable which is conditional on <quote>arm</quote>, and <quote>arm</quote> is in OVERRIDES, then the <quote>arm</quote> specific version of the variable is used rather than the non-conditional version.  Example:</para>
+                <para><screen><varname>OVERRIDES</varname> = "architecture:os:machine"
+<varname>TEST</varname> = "defaultvalue"
+<varname>TEST_os</varname> = "osspecificvalue"
+<varname>TEST_condnotinoverrides</varname> = "othercondvalue"</screen></para>
+                <para>In this example, <varname>TEST</varname> would be <literal>osspecificvalue</literal>, due to the condition <quote>os</quote> being in <varname>OVERRIDES</varname>.</para>
+            </section>
+            <section>
+                <title>Conditional appending</title>
+                <para>BitBake also supports appending and prepending to variables based on whether something is in OVERRIDES.  Example:</para>
+                <para><screen><varname>DEPENDS</varname> = "glibc ncurses"
+<varname>OVERRIDES</varname> = "machine:local"
+<varname>DEPENDS_append_machine</varname> = " libmad"</screen></para>
+                <para>In this example, <varname>DEPENDS</varname> is set to <literal>glibc ncurses libmad</literal>.</para>
+            </section>
+            <section>
+                <title>Inclusion</title>
+                <para>Next, there is the <literal>include</literal> directive, which causes BitBake to parse in whatever file you specify, and insert it at that location, which is not unlike <command>make</command>.  However, if the path specified on the <literal>include</literal> line is a relative path, BitBake will locate the first one it can find within <envar>BBPATH</envar>.</para>
+            </section>
+            <section>
+                <title>Requiring Inclusion</title>
+                <para>In contrast to the <literal>include</literal> directive, <literal>require</literal> will
+raise an ParseError if the to be included file can not be found. Otherwise it will behave just like the <literal>
+include</literal> directive.</para>

+                <para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
+                <para>The <literal>inherit</literal> directive is a means of specifying what classes of functionality your .bb requires.  It is a rudimentary form of inheritance.  For example, you can easily abstract out the tasks involved in building a package that uses autoconf and automake, and put that into a bbclass for your packages to make use of.  A given bbclass is located by searching for classes/filename.oeclass in <envar>BBPATH</envar>, where filename is what you inherited.</para>

+                <para>In BitBake, each step that needs to be run for a given .bb is known as a task.  There is a command <literal>addtask</literal> to add new tasks (must be a defined python executable metadata and must start with <quote>do_</quote>) and describe intertask dependencies.</para>
+                <para><screen>python do_printdate () {
+    import time
+    print time.strftime('%Y%m%d', time.gmtime())
+}
+
+addtask printdate before do_build</screen></para>
+                <para>This defines the necessary python function and adds it as a task which is now a dependency of do_build (the default task).  If anyone executes the do_build task, that will result in do_printdate being run first.</para>
+            </section>

+                <para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
+                <para>BitBake allows to install event handlers.  Events are triggered at certain points during operation, such as, the beginning of operation against a given .bb, the start of a given task, task failure, task success, et cetera.  The intent was to make it easy to do things like email notifications on build failure.</para>
+                <para><screen>addhandler myclass_eventhandler
+python myclass_eventhandler() {
+    from bb.event import getName

+    print("The file we run for is %s" % data.getVar('FILE', e.data, True))
+}
+</screen></para><para>
+This event handler gets called every time an event is triggered. A global variable <varname>e</varname> is defined. <varname>e</varname>.data contains an instance of bb.data. With the getName(<varname>e</varname>)
+method one can get the name of the triggered event.</para><para>The above event handler prints the name
+of the event and the content of the <varname>FILE</varname> variable.</para>
+            </section>
+            <section>
+                <title>Variants</title>
+                <para>Two Bitbake features exist to facilitate the creation of multiple buildable incarnations from a single recipe file.</para>
+                <para>The first is <varname>BBCLASSEXTEND</varname>.  This variable is a space separated list of classes to utilize to "extend" the recipe for each variant.  As an example, setting <screen>BBCLASSEXTEND = "native"</screen> results in a second incarnation of the current recipe being available.  This second incarantion will have the "native" class inherited.</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)
+  -d, --disable-psyco   disable using the psyco just-in-time compiler (not
+                        recommended)
+  -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

+                <para>As you may have seen in the usage information, or in the information about .bb files, the BBFILES variable is how the bitbake tool locates its files.  This variable is a space separated list of files that are available, and supports wildcards.
+                <example>
+                    <title>Setting BBFILES</title>
+                    <programlisting><varname>BBFILES</varname> = "/path/to/bbfiles/*.bb"</programlisting>
+                </example></para>
+                <para>With regard to dependencies, it expects the .bb to define a <varname>DEPENDS</varname> variable, which contains a space separated list of <quote>package names</quote>, which themselves are the <varname>PN</varname> variable.  The <varname>PN</varname> variable is, in general, by default, set to a component of the .bb filename.</para>
+                <example>
+                    <title>Depending on another .bb</title>
+                    <para>a.bb:

+                    <para>This example shows the usage of the PROVIDES variable, which allows a given .bb to specify what functionality it provides.</para>
+                    <para>package1.bb:
+    <screen>PROVIDES += "virtual/package"</screen>

+                    <para>As you can see, here there are two different .bb's that provide the same functionality (virtual/package).  Clearly, there needs to be a way for the person running bitbake to control which of those providers gets used.  There is, indeed, such a way.</para>
+                    <para>The following would go into a .conf file, to select package1:
+    <screen>PREFERRED_PROVIDER_virtual/package = "package1"</screen>
+                    </para>

+                <example>
+                    <title>Specifying version preference</title>
+                    <para>When there are multiple <quote>versions</quote> of a given package, bitbake defaults to selecting the most recent version, unless otherwise specified.  If the .bb in question has a <varname>DEFAULT_PREFERENCE</varname> set lower than the other .bb's (default is 0), then it will not be selected.  This allows the person or persons maintaining the repository of .bb files to specify their preferences for the default selected version.  In addition, the user can specify their preferences with regard to version.</para>
+                    <para>If the first .bb is named <filename>a_1.1.bb</filename>, then the <varname>PN</varname> variable will be set to <quote>a</quote>, and the <varname>PV</varname> variable will be set to 1.1.</para>
+                    <para>If we then have an <filename>a_1.2.bb</filename>, bitbake will choose 1.2 by default.  However, if we define the following variable in a .conf that bitbake parses, we can change that.
+    <screen>PREFERRED_VERSION_a = "1.1"</screen>

+                    <para>bbfile collections exist to allow the user to have multiple repositories of bbfiles 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.  Usage:</para>

+        # "However, as part of the session management system, there are exactly

+        #
+        #    1) When the process that dies is the session leader of a session that
+        #        is attached to a terminal device, SIGHUP is sent to all processes
+        #        in the foreground process group of that terminal device.
+        #    2) When the death of a process causes a process group to become
+        #        orphaned, and one or more processes in the orphaned group are
+        #        stopped, then SIGHUP and SIGCONT are sent to all members of the

+        # a controlling terminal.  The second case isn't so easy to dismiss.

+        # POSIX.1 requires that every STOPPED process in an orphaned process
+        # group be sent a SIGHUP signal followed by a SIGCONT signal.  Since the

+The expandData and update_data are the most expensive

+    * more shell-like features:
+        - output control, i.e. pipe output into grep, sort, etc.
+        - job control, i.e. bring running commands into background and foreground
+    * start parsing in background right after startup
+    * ncurses interface
+
+PROBLEMS:
+    * force doesn't always work
+    * readline completion for commands with more than one parameters

+
+        <para>
+            A Board Support Package (BSP) is a collection of information which together
+            defines how to support a particular hardware device, set of devices, or 
+            hardware platform. It will include information about the hardware features 
+            present on the device and kernel configuration information along with any 
+            additional hardware drivers required. It will also list any additional software 
+            components required in addition to a generic Linux software stack for both 
+            essential and optional platform features.
+        </para>
+
+        <para>
+            The intent of this document is to define a structure for these components
+            so that BSPs follow a commonly understood layout, allowing them to be 
+            provided in a common form that everyone understands. It also allows end-users
+            to become familiar with one common format and encourages standardisation 
+            of software support of hardware.
+        </para>
+
+        <para>
+            The proposed format does have elements that are specific to the Poky and 
+            OpenEmbedded build systems. It is intended that this information can be 
+            used by other systems besides Poky/OpenEmbedded and that it will be simple
+            to extract information and convert to other formats if required. The format 
+            described can be directly accepted as a layer by Poky using its standard 
+            layers mechanism, but it is important to recognise that the BSP captures all 
+            the hardware specific details in one place in a standard format, which is 
+            useful for any person wishing to use the hardware platform regardless of 
+            the build system in use.
+        </para>
+
+        <para>
+            The BSP specification does not include a build system or other tools -
+            it is concerned with the hardware specific components only. At the end 
+            distribution point the BSP may be shipped combined with a build system
+            and other tools, but it is important to maintain the distinction that these
+            are separate components which may just be combined in certain end products.

+                This optional area contains useful prebuilt kernels and userspace filesystem 
+                images appropriate to the target system. Users could use these to get a system 
+                running and quickly get started on development tasks. The exact types of binaries
+                present will be highly hardware-dependent but a README file should be present 
+                explaining how to use them with the target hardware. If prebuilt binaries are 
+                present, source code to meet licensing requirements must also be provided in

+                the BSP supports multiple machines, multiple machine configuration files
+                can be present. These filenames correspond to the values users set the

+
+            <para>
+                These files would define things like which kernel package to use

+            Say you have a recipe like pointercal which has machine-specific information in it,
+            and then you have your new BSP code in a layer. Before the .bbappend extension was
+            introduced, you'd have to copy the whole pointercal recipe and files into your layer,
+            and then add the single file for your machine, which is ugly.
+
+            .bbappend makes the above work much easier, to allow BSP-specific information to be merged
+            with the original recipe easily. When bitbake finds any X.bbappend files, they will be
+            included after bitbake loads X.bb but before finalise or anonymous methods run.
+            This allows the BSP layer to poke around and do whatever it might want to customise
+            the original recipe.
+
+            If your recipe needs to reference extra files it can use the FILESEXTRAPATH variable
+            to specify their location. The example below shows extra files contained in a folder
+            called ${PN} (the package name).

+            Then the BSP could add machine-specific config files in layer directory, which will be

+
+            <para>
+	      In some cases, a BSP may contain separately licensed IP
+	      (Intellectual Property) for a component, which imposes
+	      upon the user a requirement to accept the terms of a
+	      'click-through' license.  Once the license is accepted
+	      (in whatever form that may be, see details below) the
+	      Poky build system can then build and include the
+	      corresponding component in the final BSP image.  Some
+	      affected components may be essential to the normal
+	      functioning of the system and have no 'free' replacement
+	      i.e. the resulting system would be non-functional
+	      without them.  Other components may be simply
+	      'good-to-have' or purely elective, or if essential
+	      nonetheless have a 'free' (possibly less-capable)
+	      version which may substituted for in the BSP recipe.
+            </para>
+
+            <para>
+	      For the latter cases, where it is possible to do so from
+	      a functionality perspective, the Poky website will make
+	      available a 'de-featured' BSP completely free of
+	      encumbered IP, which can be used directly and without
+	      any further licensing requirements.  If present, this
+	      fully 'de-featured' BSP will be named meta-bsp (i.e. the
+	      normal default naming convention).  This is the simplest
+	      and therefore preferred option if available, assuming
+	      the resulting functionality meets requirements.
+            </para>
+
+            <para>
+	      If however, a non-encumbered version is unavailable or
+	      the 'free' version would provide unsuitable
+	      functionality or quality, an encumbered version can be
+	      used.  Encumbered versions of a BSP are given names of
+	      the form meta-bsp-nonfree.  There are several ways
+	      within the Poky build system to satisfy the licensing
+	      requirements for an encumbered BSP, in roughly the
+	      following order of preference:
+            </para>

+	    <itemizedlist>

+		  Get a license key (or keys) for the encumbered BSP
+		  by
+		  visiting <ulink url='https://pokylinux.org/bsp-keys.html'>https://pokylinux.org/bsp-keys.html</ulink>
+		  and give the web form there the name of the BSP
+		  and your e-mail address.

+		  After agreeing to any applicable license terms, the
+		  BSP key(s) will be immediately sent to the address
+		  given and can be used by specifying BSPKEY_&lt;keydomain&gt;
+		  environment variables when building the image:
+		</para>
+
+		<programlisting>
+		  $ BSPKEY_&lt;keydomain&gt;=&lt;key&gt; bitbake poky-image-sato
+		</programlisting>
+
+		<para>
+		  This will allow the encumbered image to be built
+		  with no change at all to the normal build process.
+		</para>
+
+		<para>
+		  Equivalently and probably more conveniently, a line
+		  for each key can instead be put into the user's
+		  local.conf file.
+		</para>
+
+		<para>
+		  The &lt;keydomain&gt; component of the
+		  BSPKEY_&lt;keydomain&gt; is required because there
+		  may be multiple licenses in effect for a give BSP; a
+		  given &lt;keydomain&gt; in such cases corresponds to
+		  a particular license.  In order for an encumbered
+		  BSP encompassing multiple key domains to be built
+		  successfully, a &lt;keydomain&gt; entry for each
+		  applicable license must be present in local.conf or
+		  supplied on the command-line.

+		  Do nothing - build as you normally would, and follow
+		  any license prompts that originate from the
+		  encumbered BSP (the build will cleanly stop at this
+		  point).  These usually take the form of instructions
+		  needed to manually fetch the encumbered package(s)
+		  and md5 sums into e.g. the poky/build/downloads
+		  directory.  Once the manual package fetch has been
+		  completed, restarting the build will continue where
+		  it left off, this time without the prompt since the
+		  license requirements will have been satisfied.

+		  Get a full-featured BSP recipe rather than a key, by
+		  visiting
+		  <ulink url='https://pokylinux.org/bsps.html'>https://pokylinux.org/bsps.html</ulink>.
+		  Accepting the license agreement(s) presented will
+		  subsequently allow you to download a tarball
+		  containing a full-featured BSP legally cleared for
+		  your use by the just-given license agreement(s).
+		  This method will also allow the encumbered image to
+		  be built with no change at all to the normal build
+		  process.
