-'Poky' is a combined cross build system and linux distribution based
-upon OpenEmbedded. It features support for building X11/Matchbox/GTK
-based filesystem images for various embedded devices and boards.
+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.
 
+Poky has an extensive handbook, the source of which is contained in
+the handbook directory. For compiled HTML or pdf versions of this, 
+see the Poky website http://pokylinux.org.
 
-Required Packages
-===
-
-Running Poky on Debian based distributions requires the following
-extra packages be installed;
-
-build-essential
-diffstat
-texinfo
-texi2html
-cvs
-subversion
-gawk
-bochsbios (to run qemux86 images)
-
-You also need to install the qemu from http://debian.o-hand.com/. A
-poky-depends deb is also available from this source which will install 
-all the dependencies mentioned above for you.
-
-Alternatively poky can build qemu itself, but for this you need the
-following packages installed;
-
-gcc-3.4
-libsdl1.2-dev
-zlib1g-dev
-
-You will also need to comment out ASSUME_PROVIDED += "qemu-native"' in  
-build/conf/local.conf.
-
-Building under other distro's such as Fedora is known to work. Use the above
-package names as a guide for dependencies.
-
-Building An Image
-===
-
-Simply run;
-
-% source poky-init-build-env
-% bitbake poky-image-sato
-
-This will result in an ext2 image and kernel for qemu arm (see scripts dir).
-
-To build for other machine types see MACHINE in build/conf/local.conf
-
-Other image targets such as poky-image-sdk or poky-image-minimal are available, 
-see meta/packages/images/*.

-                         Using Poky - Poky Commands
-                         ==========================
-
-Bitbake
-=======
-
-Bitbake is the tool at the heart of poky and is responsible for parsing the 
-metadata, generating a list of tasks from it and then executing them. To see a 
-list of the options it supports look at "bitbake --help".
-
-The most common usage is "bitbake <packagename>" where <packagename> is the name
-of the package you wish to build. This often equates to the first part of a .bb 
-filename so to run the matchbox-desktop_1.2.3.bb file, you might type "bitbake
-matchbox-desktop. Several different versions of matchbox-desktop might exist
-and bitbake will choose the one selected by the distribution configuration.
-Bitbake will also try to execute any dependent tasks first so before building
-matchbox-desktop it would build a cross compiler and glibc if not already built.
-
-
-Bitbake - Package Tasks
-=======================
-
-Any given package consists of a set of tasks, in most cases the series is fetch, 
-unpack, patch, configure, compile, install, package, package_write and build. 
-The default task is "build" and any tasks this depends on are built first hence 
-the standard bitbake behaviour. There are some tasks such as devshell which are 
-not part of the default build chain. If you wish to run such a task you can use 
-the "-c" option to bitbake e.g. "bitbake matchbox-desktop -c devshell".
-
-If you wish to rerun a task you can use the force option "-f". A typical usage 
-case might look like:
-
-% bitbake matchbox-desktop
-[change some source in the WORKDIR for example]
-% bitbake matchbox-desktop -c compile -f
-% bitbake matchbox-desktop
-
-which would build matchbox-desktop, then recompile it. The final command reruns 
-all tasks after the compile (basically the packaging tasks) since bitbake will 
-notice the the compile has been rerun and hence the other tasks also need to run 
-again.
-
-You can view a list of tasks in a given package by running the listtasks task
-e.g. "bitbake matchbox-desktop -c listtasks".
-
-
-Bitbake - Dependency Graphs
-===========================
-
-Sometimes it can be hard to see why bitbake wants to build some other packages
-before a given package you've specified. "bitbake matchbox-desktop -g" will 
-create a task-depends.dot file in the current directory. This shows which 
-packages and tasks depend on which other packages and tasks and it useful for 
-debugging purposes.
-
-
-Bitbake - Advanced Usage
-========================
-
-Debug output from bitbake can be seen with the "-D" option and can sometimes 
-give more information about what bitbake is doing and/or why. Each -D options 
-increases the logging level, the most common usage being "-DDD".
-
-If you really want to build a specific .bb file, you can use the form "bitbake
--b somepath/somefile.bb". Note that this will not check the dependencies so this
-option should only be used when you know the dependencies already exist. You can
-specify fragments of the filename and bitbake will see if it can find a unique 
-match.
-
-The -e option will dump the resulting environment for either the configuration 
-(no package specified) or for a specific package when specified with the -b 
-option.
-
-The -k option will cause bitbake to try and continue even if a task fails. It 
-can be useful for world or unattended builds.
-
-The -s option lists all the versions of packages that bitbake will use.
-
-
-Bitbake - More Information
-==========================
-
-See the bitbake user manual at: http://bitbake.berlios.de/manual/
-
-QEMU
-====
-
-Running images built by poky under qemu is possible within the poky environment
-through the "runqemu" command. It has the form:
-
-runqemu MACHINE IMAGETYPE ZIMAGE IMAGEFILE
-
-where:
-
-MACHINE - the machine to emulate (qemux86, qemuarm, spitz, akita)
-IMAGETYPE - the type of image to use (nfs or ext2)
-ZIMAGE - location of the kernel binary to use
-IMAGEFILE - location of the image file to use
-(common options are in brackets)
-
-MACHINE is mandatory, the others are optional.
-
-This assumes a suitable qemu binary is available with support for a given 
-machine. For further information see scripts/poky-qemu.README.

+                     Poky Hardware Reference Guide
+                     =============================
+
+This file gives details about using Poky with different hardware reference
+boards and consumer devices. A full list of target machines can be found by 
+looking in the meta/conf/machine/ directory. If in doubt about using Poky with 
+your hardware, consult the documentation for your board/device. To discuss 
+support for further hardware reference boards/devices please contact OpenedHand.
+
+QEMU Emulation Images (qemuarm and qemux86)
+===========================================
+
+To simplify development Poky supports building images to work with the QEMU
+emulator in system emulation mode. Two architectures are currently supported,
+ARM (via qemuarm) and x86 (via qemux86). Use of the QEMU images is covered
+in the Poky Handbook.
+
+Hardware Reference Boards
+=========================
+
+The following boards are supported by Poky:
+
+  * Compulab CM-X270 (cm-x270)
+  * Compulab EM-X270 (em-x270)
+  * FreeScale iMX31ADS (mx31ads)
+  * Marvell PXA3xx Zylonite (zylonite)
+  * Logic iMX31 Lite Kit (mx31litekit)
+  * Phytec phyCORE-iMX31 (mx31phy)
+
+For more information see board's section below. The Poky MACHINE setting
+corresponding to the board is given in brackets.
+
+Consumer Devices
+================
+
+The following consumer devices are supported by Poky:
+
+  * FIC Neo1973 GTA01 smartphone (fic-gta01)
+  * HTC Universal (htcuniversal)
+  * Nokia 770/N800/N810 Internet Tablets (nokia770 and nokia800)
+  * Sharp Zaurus SL-C7x0 series (c7x0)
+  * Sharp Zaurus SL-C1000 (akita)
+  * Sharp Zaurus SL-C3x00 series (spitz)
+
+For more information see board's section below. The Poky MACHINE setting
+corresponding to the board is given in brackets.
+
+Poky Boot CD (bootcdx86)
+========================
+
+The Poky boot CD iso images are designed as a demonstration of the Poky 
+environment and to show the versatile image formats Poky can generate. It will
+run on Pentium2 or greater PC style computers. The iso image can be 
+burnt to CD and then booted from.
+
+
+                          Hardware Reference Boards
+                          =========================
+
+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

-Using Poky generated host SDK
-=============================
-
-How to build host SDK
-====
-
-You need to setup Poky and then run one command:
-
-$ bitbake meta-toolchain
-
-Result would be tarball in tmp/deploy/sdk/ with everything needed to build for
-your target device. Unpack this in / directory - toolchain will reside in
-/usr/local/poky/arm/ dir.
-
-Usage of SDK
-=====
-
-First add toolchain into PATH:
-
-$ export PATH=/usr/local/poky/arm/bin/:$PATH
-
-Compiler is 'arm-poky-linux-gnueabi-gcc'. Building 'helloworld' example is
-simple:
-
-$ arm-poky-linux-gnueabi-gcc hello.c -o hello
-$ file hello
-hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.6.14, dynamically linked (uses shared libs), not stripped
-
-Autotools and SDK
-======
-
-'Configure' scripts allow to specify Host, Target, Build architecture. To build
-with Poky SDK you need to specify:
-
-./configure --target=arm-poky-linux-gnueabi --host=arm-poky-linux-gnueabi
-
-
-Using packages from Poky
-========
-
-During development it is often situation that we want to use some libraries
-which are available in Poky build. Their packages need to be unpacked to
-/usr/local/poky/arm/arm-poky-linux-gnueabi/ directory.
-
-For example to add libiw (from wireless-tools package) you need to unpack two
-packages:
-
-libiw29_29-pre20-r0_armv5te.ipk
-libiw-dev_29-pre20-r0_armv5te.ipk

-                 A walk through the poky directory tree
-                 ======================================
-
-Poky consists of several components and understanding what these are and where 
-they each live is one of the keys to using it.
-
-Top level core components
-=========================
-
-
-bitbake/
-
-A copy of bitbake is included within poky for ease of use and resides here. 
-This should usually be the same as a standard bitbake release from the bitbake 
-project. Bitbake is a metadata interpreter and is responsible for reading the 
-poky metadata and running the tasks it defines. Failures are usually from the
-metadata and not bitbake itself and most users don't need to worry about 
-bitbake. bitbake/bin is placed into the PATH environmental variable so bitbake 
-can be found.
-
-build/
-
-This directory contains user configuration files and the output from Poky is 
-also placed here.
-
-meta/
-
-The core metadata - this is the key part of poky. Within this directory there 
-are definitions of the machines, the poky distribution and the packages that 
-make up a given system.
-
-meta-extras/
-
-Similar to meta containing some extra package files not included in standard 
-poky, disabled by default and hence not supported as part of poky.
-
-scripts/
-
-Various integration scripts which implement extra functionality in the poky 
-environment for example the qemu scripts. This directory is appended to the 
-PATH environmental variable.
-
-sources/
-
-Whilst not part of a checkout, poky will create this directory as part of any 
-build. Any downloads are placed in this directory (as specified by the
-DL_DIR variable). This directory can be shared between poky builds to save 
-downloading files multiple times. SCM checkouts are also stored here as e.g.
-sources/svn/, sources/cvs/ or sources/git/ and the sources directory may contain 
-archives of checkouts for various revisions or dates.
-
-Its worth noting that bitbake creates .md5 stamp files for downloads. It uses 
-these to mark downloads as complete as well as for checksum and access 
-accounting purposes. If you add a file manually to the directory, you need to
-touch the corresponding .md5 file too.
-
-poky-init-build-env
-
-This script is used to setup the poky build environment. Sourcing this file in
-a shell makes changes to PATH and sets other core bitbake variables based on the
-current working directory. You need to use this before running poky commands.
-Internally it uses scripts within the scripts/ directory to do the bulk of the 
-work.
-
-
-The Build Directory
-===================
-
-conf/local.conf
-
-This file contains all the local user configuration of poky. If it isn't 
-present, its created from local.conf.sample. That file contains documentation
-on the various standard options which can be configured there although any 
-standard conf file variable can be also be set here and usually overrides any
-variable set elsewhere within poky.
-
-Edit this file to set the MACHINE you want to build for, which package types you
-which to use (PACKAGE_CLASSES) or where downloaded files should go (DL_DIR) for 
-exmaple.
-
-tmp/
-
-This is created by bitbake if it doesn't exist and is where all the poky output
-is placed. To clean poky and start a build from scratch (other than downloads), 
-you can wipe this directory. tmp has some important subcomponents detailed 
-below.
-
-tmp/cache/
-
-When bitbake parses the metadata it creates a cache file of the result which can
-be used when subsequently running the command. These are stored here, usually on 
-a per machine basis.
-
-tmp/cross/
-
-The cross compiler when generated is placed into this directory and those
-beneath it.
-
-tmp/deploy/
-
-Any 'end result' output from poky is placed under here.
-
-tmp/deploy/deb/
-
-Any .deb packages emitted by poky are placed here, sorted into feeds for 
-different architecture types.
-
-tmp/deploy/images/
-
-Complete filesystem images are placed here. If you want to flash the resulting 
-image from a build onto a device, look here for them.
-
-tmp/deploy/ipk/
-
-Any resulting .ipk packages emitted by poky are placed here.
-
-tmp/rootfs/
-
-This is a temporary scratch area used when creating filesystem images. It is run
-under fakeroot and is not useful once that fakeroot session has ended as 
-information is lost. It is left around since it is still useful in debugging 
-image creation problems.
-
-tmp/staging/
-
-Any package needing to share output with other packages does so within staging.
-This means it contains any shared header files and any shared libraries amongst
-other data. It is subdivided by architecture so multiple builds can run within
-the one build directory.
-
-tmp/stamps/
-
-This is used by bitbake for accounting purposes to keep track of which tasks 
-have been run and when. It is also subdivided by architecture. The files are 
-empty and the important information is the filenames and timestamps.
-
-tmp/work/
-
-Each package build by bitbake is worked on its own work directory. Here, the 
-source is unpacked, patched, configured, compiled etc. It is subdivided by 
-architecture.
-
-It is worth considering the structure of a typical work directory. An example is
-the linux-rp kernel, version 2.6.20 r7 on the machine spitz built within poky
-which would result in a work directory of 
-"tmp/work/spitz-poky-linux-gnueabi/linux-rp-2.6.20-r7", referred to as WORKDIR.
-
-Within this, the source is unpacked to linux-2.6.20 and then patched by quilt
-hence the existence of the standard quilt directories linux-2.6.20/patches and 
-linux-2.6.20/.pc. Within the linux-2.6.20 directory, standard quilt commands 
-can be used.
-
-There are other directories generated within WORKDIR. The most important/useful 
-is WORKDIR/temp which has log files for each task (log.do_*.pid) and the scripts
-bitbake runs for each task (run.do_*.pid). WORKDIR/image is where "make install"
-places its output which is then split into subpackages within WORKDIR/install.
-
-
-The Metadata
-============
-
-As mentioned previously, this is the core of poky. It has several important 
-subdivisions:
-
-meta/classes/
-
-Contains the *.bbclass files. Class files are used to abstract common code 
-allowing it to be reused by multiple packages. The base.bbclass file is 
-inherited by every package. Examples of other important classes are 
-autotools.bbclass which in theory allows any "autotooled" package to work with 
-poky with minimal effort or kernel.bbclass which contains common code and 
-functions for working with the linux kernel. Functions like image generation or 
-packaging also have their specific class files (image.bbclass, rootfs_*.bbclass 
-and package*.bbclass).
-
-meta/conf/
-
-This is the core set of configuration files which start from bitbake.conf and 
-from which all other configuration files are included (see the includes at the 
-end of the file, even local.conf is loaded from there!). Whilst bitbake.conf 
-sets up the defaults, often these can be overridden by user (local.conf),
-machine or distribution configuration files.
-
-meta/conf/machine/
-
-Contains all the machine configuration files. If you set MACHINE="spitz", the 
-end result is poky looking for a spitz.conf file in this directory. The includes
-directory contains various data common to multiple machines. If you want to add
-support for a new machine to poky, this is the directory to look in.
-
-meta/conf/distro/
-
-Any distribution specific configuration is controlled from here. OpenEmbedded 
-supports multiple distributions of which poky is one. Poky only contains the 
-poky distribution so poky.conf is the main file here.  This includes the 
-versions and SRCDATES for applications which are configured here. An example of 
-an alternative configuration is poky-bleeding.conf although this mainly inherits
-its configuration from poky itself.
-
-packages/
-
-Each application (package) poky can build has an associated .bb file which are 
-all stored under this directory. Poky finds them through the BBFILES variable 
-which defaults to packages/*/*.bb. Adding a new piece of software to poky 
-consists of adding the appropriate .bb file. The .bb files from OpenEmbedded
-upstream are usually compatible although they are not supported.
-
-site/
-
-Certain autoconf test results cannot be determined when cross compiling since it 
-can't run tests on a live system. This directory therefore contains a list of 
-cached results for various architectures which is passed to autoconf.

+		       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>
+

+	- Cooker: Remove a debug message from the parsing loop to lower overhead
+	- Convert build.py exec_task to use getVarFlags
+	- Update shell to use cooker.buildFile
+	- Add StampUpdate event
+	- Convert -b option to use taskdata/runqueue

+	- Improve runtime PREFERRED_PROVIDERS warning message
+	- Add BB_STAMP_WHITELIST option which contains a list of stamps to ignore when
+	  checking stamp dependencies and using a BB_STAMP_POLICY of "whitelist"
+	- 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
+	- Add PERSISTENT_DIR to store the PersistData in a persistent
+	  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 dictonary before running tasks
+	- Correctly add a task override in the form task-TASKNAME.
+	- 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)
+
+Changes in Bitbake 1.8.0:
+	- Release 1.7.x as a stable series
+
+Changes in BitBake 1.7.x:
+	- Major updates of the dependency handling and execution
+	  of tasks. Code from bin/bitbake replaced with runqueue.py
+	  and taskdata.py
+	- New task execution code supports multithreading with a simplistic
+	  threading algorithm controlled by BB_NUMBER_THREADS
+	- Change of the SVN Fetcher to keep the checkout around
+	  courtsey of Paul Sokolovsky (#1367)
+	- PATH fix to bbimage (#1108)

+	- Allow 'interactive' tasks
+	- Logging message improvements
+	- Drop now uneeded BUILD_ALL_DEPS variable
+	- Add support for wildcards to -b option
+	- Major overhaul of the fetchers making a large amount of code common
+	  including mirroring code
+	- Fetchers now touch md5 stamps upon access (to show activity)
+	- Fix -f force option when used without -b (long standing bug)
+	- Add expand_cache to data_cache.py, caching expanded data (speedup)
+	- Allow version field in DEPENDS (ignored for now)
+	- Add abort flag support to the shell
+	- Make inherit fail if the class doesn't exist (#1478)
+	- Fix data.emit_env() to expand keynames as well as values
+	- Add ssh fetcher
+	- Add perforce fetcher
+	- Make PREFERRED_PROVIDER_foobar defaults to foobar if available
+	- Share the parser's mtime_cache, reducing the number of stat syscalls
+	- Compile all anonfuncs at once! 
+	  *** Anonfuncs must now use common spacing format ***
+	- Memorise the list of handlers in __BBHANDLERS and tasks in __BBTASKS
+	  This removes 2 million function calls resulting in a 5-10% speedup

+	- ASSUME_PROVIDED allowed to include runtime packages
+	- git fetcher cleanup and efficency improvements
+	- Change the format of the cache
+	- Update usermanual to document the Fetchers
+	- Major changes to caching with a new strategy
+	  giving a major performance increase when reparsing
+	  with few data changes

+	- kill default arguments in methods in the bb.fetch module
+	- the http/https/ftp fetcher will fail if the to be 
+	  downloaded file was not found in DL_DIR (this is needed
+	  to avoid unpacking the sourceforge mirror page)
+	- Switch to a cow like data instance for persistent and non
+	  persisting mode (called data_smart.py)
+	- Changed the callback of bb.make.collect_bbfiles to carry
+	  additional parameters
+	- Drastically reduced the amount of needed RAM by not holding
+	  each data instance in memory when using a cache/persistent
+	  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

+      #      is attached to a terminal device, SIGHUP is sent to all processes
+      #      in the foreground process group of that terminal device.

@@ -1,8 +1,168 @@
-Changes in Bitbake 1.8.x:
+Changes in BitBake 1.8.x:
+	- Add bb.utils.prune_suffix function
+ 
+Changes in BitBake 1.8.12:
+	- Fix -f (force) in conjunction with -b
+	- Fix exit code for build failures in --continue mode
+	- Fix git branch tags fetching
+	- Change parseConfigurationFile so it works on real data, not a copy
+	- Handle 'base' inherit and all other INHERITs from parseConfigurationFile 
+	  instead of BBHandler
+	- Fix getVarFlags bug in data_smart
+	- Optmise cache handling by more quickly detecting an invalid cache, only 
+	  saving the cache when its changed, moving the cache validity check into
+	  the parsing loop and factoring some getVar calls outside a for loop
+	- Cooker: Remove a debug message from the parsing loop to lower overhead
+	- Convert build.py exec_task to use getVarFlags
+	- Update shell to use cooker.buildFile
+	- Add StampUpdate event
+	- Convert -b option to use taskdata/runqueue
+	- Remove digraph and switch to new stamp checking code. exec_task no longer
+	  honours dependencies
+	- Make fetcher timestamp updating non-fatal when permissions don't allow 
+	  updates
+	- Add BB_SCHEDULER variable/option ("completion" or "speed") controlling
+	  the way bitbake schedules tasks
+	- Add BB_STAMP_POLICY variable/option ("perfile" or "full") controlling
+	  how extensively stamps are looked at for validity
+	- When handling build target failures make sure idepends are checked and
+	  failed where needed. Fixes --continue mode crashes.
+	- Fix problems with recrdeptask handling where some idepends weren't handled
+	  correctly.
+	- Work around refs/HEAD issues with git over http (#3410)
+	- Add proxy support to the CVS fetcher (from Cyril Chemparathy)
+	- Improve runfetchcmd so errors are seen and various GIT variables are exported
+	- Add ability to fetchers to check URL validity without downloading
+	- Improve runtime PREFERRED_PROVIDERS warning message
+	- Add BB_STAMP_WHITELIST option which contains a list of stamps to ignore when
+	  checking stamp dependencies and using a BB_STAMP_POLICY of "whitelist"
+	- 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
+	- Add PERSISTENT_DIR to store the PersistData in a persistent
+	  directory != the cache dir.
+	- Add md5 and sha256 checksum generation functions to utils.py
+	- Make sure Build Completed events are generated even when tasks fail
+	- Correctly handle '-' characters in class names (#2958)
+	- Make sure expandKeys has been called on the data dictonary before running tasks
+	- Correctly add a task override in the form task-TASKNAME.
+	- 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
+	- 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)
+
+Changes in BitBake 1.8.10:
+	- Psyco is available only for x86 - do not use it on other architectures.
+	- Fix a bug in bb.decodeurl where http://some.where.com/somefile.tgz decoded to host="" (#1530)
+	- Warn about malformed PREFERRED_PROVIDERS (#1072)
+	- Add support for BB_NICE_LEVEL option (#1627)
+	- Sort initial providers list by default preference (#1145, #2024)
+	- Improve provider sorting so prefered versions have preference over latest versions (#768)
+	- Detect builds of tasks with overlapping providers and warn (will become a fatal error) (#1359)
+	- Add MULTI_PROVIDER_WHITELIST variable to allow known safe multiple providers to be listed
+	- Handle paths in svn fetcher module parameter
+	- Support the syntax "export VARIABLE"
+	- Add bzr fetcher
+	- Add support for cleaning directories before a task in the form:
+	  do_taskname[cleandirs] = "dir"
+	- bzr fetcher tweaks from Robert Schuster (#2913)
+	- Add mercurial (hg) fetcher from Robert Schuster (#2913)
+	- Fix bogus preferred_version return values
+	- Fix 'depends' flag splitting
+	- Fix unexport handling (#3135)
+	- Add bb.copyfile function similar to bb.movefile (and improve movefile error reporting)
+	- Allow multiple options for deptask flag
+	- Use git-fetch instead of git-pull removing any need for merges when 
+	  fetching (we don't care about the index). Fixes fetch errors.
+	- Add BB_GENERATE_MIRROR_TARBALLS option, set to 0 to make git fetches 
+	  faster at the expense of not creating mirror tarballs.
+	- SRCREV handling updates, improvements and fixes from Poky
+	- Add bb.utils.lockfile() and bb.utils.unlockfile() from Poky
+	- Add support for task selfstamp and lockfiles flags
+	- Disable task number acceleration since it can allow the tasks to run 
+	  out of sequence
+	- Improve runqueue code comments
+	- Add task scheduler abstraction and some example schedulers
+	- Improve circular dependency chain debugging code and user feedback
+	- Don't give a stacktrace for invalid tasks, have a user friendly message (#3431)
+	- Add support for "-e target" (#3432)
+	- Fix shell showdata command (#3259)
+	- Fix shell data updating problems (#1880)
+	- Properly raise errors for invalid source URI protocols
+	- Change the wget fetcher failure handling to avoid lockfile problems
+	- Add git branch support
+	- Add support for branches in git fetcher (Otavio Salvador, Michael Lauer)
+	- Make taskdata and runqueue errors more user friendly
+	- Add norecurse and fullpath options to cvs fetcher
+	- bb.utils.prunedir can cope with symlinks to directories without exceptions
+
+Changes in Bitbake 1.8.8:
+	- Rewrite svn fetcher to make adding extra operations easier 
+	  as part of future SRCDATE="now" fixes
+	  (requires new FETCHCMD_svn definition in bitbake.conf)
+	- Change SVNDIR layout to be more unique (fixes #2644 and #2624)
+	- Import persistent data store from trunk
+	- Sync fetcher code with that in trunk, adding SRCREV support for svn
+	- Add ConfigParsed Event after configuration parsing is complete
+	- data.emit_var() - only call getVar if we need the variable
+	- Stop generating the A variable (seems to be legacy code)
+	- Make sure intertask depends get processed correcting in recursive depends
+	- Add pn-PN to overrides when evaluating PREFERRED_VERSION
+	- Improve the progress indicator by skipping tasks that have 
+	  already run before starting the build rather than during it
+	- Add profiling option (-P)
+	- Add BB_SRCREV_POLICY variable (clear or cache) to control SRCREV cache
+	- Add SRCREV_FORMAT support
+	- Fix local fetcher's localpath return values
+	- Apply OVERRIDES before performing immediate expansions
+	- Allow the -b -e option combination to take regular expressions
+	- Add plain message function to bb.msg
+	- Sort the list of providers before processing so dependency problems are 
+	  reproducible rather than effectively random
+	- Add locking for fetchers so only one tries to fetch a given file at a given time
+	- Fix int(0)/None confusion in runqueue.py which causes random gaps in dependency chains
+	- Fix handling of variables with expansion in the name using _append/_prepend
+	  e.g. RRECOMMENDS_${PN}_append_xyz = "abc"
+	- Expand data in addtasks
+ 	- Print the list of missing DEPENDS,RDEPENDS for the "No buildable providers available for required...."
+ 	  error message.
+	- Rework add_task to be more efficient (6% speedup, 7% number of function calls reduction)
+	- Sort digraph output to make builds more reproducible
+	- Split expandKeys into two for loops to benefit from the expand_cache (12% speedup)
+	- runqueue.py: Fix idepends handling to avoid dependency errors
+	- Clear the terminal TOSTOP flag if set (and warn the user)
+	- Fix regression from r653 and make SRCDATE/CVSDATE work for packages again
+
+Changes in Bitbake 1.8.6:
 	- Correctly redirect stdin when forking
 	- If parsing errors are found, exit, too many users miss the errors
 	- Remove supriours PREFERRED_PROVIDER warnings
-	- Start to fix path quoting
 
 Changes in Bitbake 1.8.4:
 	- Make sure __inherit_cache is updated before calling include() (from Michael Krelin)

-   DESCRIPTION
-   -----------
-
-   lemon parser specification file for a BitBake input file parser.
-
-   Most of the interesting shenanigans are done in the lexer.  The
-   BitBake grammar is not regular.  In order to emit tokens that
-   the parser can properly interpret in LALR fashion, the lexer
-   manages the interpretation state.  This is why there are ISYMBOLs,
-   SYMBOLS, and TSYMBOLS.
-
-   This parser was developed by reading the limited available
-   documentation for BitBake and by analyzing the available BB files.
-   There is no assertion of correctness to be made about this parser.

-   DESCRIPTION
-   -----------
-
-   flex lexer specification for a BitBake input file parser.
-
-   Unfortunately, flex doesn't welcome comments within the rule sets.
-   I say unfortunately because this lexer is unreasonably complex and
-   comments would make the code much easier to comprehend.
-
-   The BitBake grammar is not regular.  In order to interpret all
-   of the available input files, the lexer maintains much state as it
-   parses.  There are places where this lexer will emit tokens that
-   are invalid.  The parser will tend to catch these. 
-
-   The lexer requires C++ at the moment.  The only reason for this has
-   to do with a very small amount of managed state.  Producing a C
-   lexer should be a reasonably easy task as long as the %reentrant
-   option is used.
-
-
-   NOTES
-   -----
-
-   o RVALUES.  There are three kinds of RVALUES.  There are unquoted
-     values, double quote enclosed strings, and single quote 
-     strings.  Quoted strings may contain unescaped quotes (of either
-     type), *and* any type may span more than one line by using a
-     continuation '\' at the end of the line.  This requires us to
-     recognize all types of values with a single expression.
-     Moreover, the only reason to quote a value is to include
-     trailing or leading whitespace.  Whitespace within a value is
-     preserved, ugh.
-
-   o CLASSES.  C_ patterns define classes.  Classes ought not include
-     a repitition operator, instead letting the reference to the class
-     define the repitition count.
-
-     C_SS - symbol start
-     C_SB - symbol body
-     C_SP - whitespace
