+Ubiquiti Networks RouterStation Pro (routerstationpro)
+======================================================

-The EdgeRouter Lite is part of the EdgeMax series. It is a MIPS64 router
-(based on the Cavium Octeon processor) with 512MB of RAM, which uses an
-internal USB pendrive for storage.
+The RouterStation Pro is an Atheros AR7161 MIPS-based board. Geared towards
+networking applications, it has all of the usual features as well as three
+type IIIA mini-PCI slots and an on-board 3-port 10/100/1000 Ethernet switch,
+in addition to the 10/100/1000 Ethernet WAN port which supports
+Power-over-Ethernet.

 Setup instructions
 ------------------

 You will need the following:
-* RJ45 -> serial ("rollover") cable connected from your PC to the CONSOLE
-  port on the device
-* Ethernet connected to the first ethernet port on the board
+* A serial cable - female to female (or female to male + gender changer)
+  NOTE: cable must be straight through, *not* a null modem cable.
+* USB flash drive or hard disk that is able to be powered from the
+  board's USB port.
+* tftp server installed on your workstation

-If using NFS as part of the setup process, you will also need:
-* NFS root setup on your workstation
-* TFTP server installed on your workstation (if fetching the kernel from
-  TFTP, see below).
+NOTE: in the following instructions it is assumed that /dev/sdb corresponds
+to the USB disk when it is plugged into your workstation. If this is not the
+case in your setup then please be careful to substitute the correct device
+name in all commands where appropriate.

+6) Connect the board's serial port to your workstation and then start up
+your favourite serial terminal so that you will be able to interact with
+the serial console. If you don't have a favourite, picocom is suggested:

--- Booting from USB root ---
+  $ picocom /dev/ttyUSB0 -b 115200

-To boot from the USB disk, you either need to remove it from the edgerouter
-box and populate it from another computer, or use a previously booted NFS
-image and populate from the edgerouter itself.
+7) Connect the network into eth0 (the one that is NOT the 3 port switch). If
+you are using power-over-ethernet then the board will power up at this point.

-Type 1: Mounted USB disk
------------------------
+8) Start up the board, watch the serial console. Hit Ctrl+C to abort the
+autostart if the board is configured that way (it is by default). The
+bootloader's fconfig command can be used to disable autostart and configure
+the IP settings if you need to change them (default IP is 192.168.1.20).

-To boot from the USB disk there are two available partitions on the factory
-USB storage. The rest of this guide assumes that these partitions are left
-intact. If you change the partition scheme, you must update your boot method
-appropriately.
+9) Make the kernel (tmp/deploy/images/vmlinux-routerstationpro.bin) available
+on the tftp server.

-The standard partitions are:
+10) If you are going to write the kernel to flash (optional - see "Booting a
+kernel directly" below for the alternative), remove the current kernel and
+rootfs flash partitions. You can list the partitions using the following
+bootloader command:

-  - 1: vfat partition containing factory kernels
-  - 2: ext3 partition for the root filesystem.
+  RedBoot> fis list

-You can place the kernel on either partition 1, or partition 2, but the roofs
-must go on partition 2 (due to its size).
+You can delete the existing kernel and rootfs with these commands:

-Note: If you place the kernel on the ext3 partition, you must re-create the
-      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
-      cannot read the partition otherwise.
+  RedBoot> fis delete kernel
+  RedBoot> fis delete rootfs

-Steps:
+--- Booting a kernel directly ---

- 1. Remove the USB disk from the edgerouter and insert it into a computer
-    that has access to your build artifacts.
+1) Load the kernel using the following bootloader command:

- 2. Copy the kernel image to the USB storage (assuming discovered as 'sdb' on
-    the development machine):
+  RedBoot> load -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin

-    2a) if booting from vfat
- 
-        # mount /dev/sdb1 /mnt
-        # cp tmp/deploy/images/edgerouter/vmlinux /mnt
-        # umount /mnt
+You should see a message on it being successfully loaded.

-    2b) if booting from ext3
+2) Execute the kernel:

-        # mkfs.ext3 -I 128 /dev/sdb2
-        # mount /dev/sdb2 /mnt
-        # mkdir /mnt/boot
-        # cp tmp/deploy/images/edgerouter/vmlinux /mnt/boot
-        # umount /mnt
+  RedBoot> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"

- 3. Extract the rootfs to the USB storage ext3 partition
+Note that specifying the command line with -c is important as linux-yocto does
+not provide a default command line.

-        # mount /dev/sdb2 /mnt
-        # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /mnt
-        # umount /mnt
+--- Writing a kernel to flash ---

- 4. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
-    command line:
+1) Go to your tftp server and gzip the kernel you want in flash. It should
+halve the size.

- 5. Load the kernel and boot:
+2) Load the kernel using the following bootloader command:

-    5a) vfat boot
+  RedBoot> load -r -b 0x80600000 -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin.gz

-         => fatload usb 0:1 $loadaddr vmlinux
+This should output something similar to the following:

-    5b) ext3 boot
+  Raw file loaded 0x80600000-0x8087c537, assumed entry at 0x80600000

-         => ext2load usb 0:2 $loadaddr boot/vmlinux
- 
-    => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
- 
+Calculate the length by subtracting the first number from the second number
+and then rounding the result up to the nearest 0x1000.

-Type 2: NFS
-----------
+3) Using the length calculated above, create a flash partition for the kernel:

-Note: If you place the kernel on the ext3 partition, you must re-create the
-      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
-      cannot read the partition otherwise.
+  RedBoot> fis create -b 0x80600000 -l 0x240000 kernel

-      These boot instructions assume that you have recreated the ext3 filesystem with
-      128 byte inodes, you have an updated uboot or you are running and image capable
-      of making the filesystem on the board itself.
+(change 0x240000 to your rounded length -- change "kernel" to whatever
+you want to name your kernel)

+--- Booting a kernel from flash ---

- 1. Boot from NFS root
+To boot the flashed kernel perform the following steps.

- 2. Mount the USB disk partition 2 and then extract the contents of
-    tmp/deploy/core-image-XXXX.tar.bz2 into it.
+1) At the bootloader prompt, load the kernel:

-    Before starting, copy core-image-minimal-xxx.tar.bz2 and vmlinux into
-    rootfs path on your workstation.
+  RedBoot> fis load -d -e kernel

-    and then,
-  
-      # mount /dev/sda2 /media/sda2
-      # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /media/sda2
-      # cp vmlinux /media/sda2/boot/vmlinux
-      # umount /media/sda2
-      # reboot
+(Change the name "kernel" above if you chose something different earlier)

- 3. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
-    command line:
+(-e means 'elf', -d 'decompress')

-    # reboot
+2) Execute the kernel using the exec command as above.

- 4. Load the kernel and boot:
+--- Automating the boot process ---
+
+After writing the kernel to flash and testing the load and exec commands
+manually, you can automate the boot process with a boot script.
+
+1) RedBoot> fconfig
+   (Answer the questions not specified here as they pertain to your environment)
+2) Run script at boot: true
+  Boot script: 
+  .. fis load -d -e kernel
+  .. exec
+  Enter script, terminate with empty line
+  >> fis load -d -e kernel
+  >> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"
+  >> 
+3) Answer the remaining questions and write the changes to flash:
+  Update RedBoot non-volatile configuration - continue (y/n)? y
+  ... Erase from 0xbfff0000-0xc0000000: .
+  ... Program from 0x87ff0000-0x88000000 at 0xbfff0000: .
+4) Power cycle the board.

-      => ext2load usb 0:2 $loadaddr boot/vmlinux
-      => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)

-Manual Organization
-===================
-
-Folders exist for individual manuals as follows:
-
-* bitbake-user-manual      - The BitBake User Manual

-Each folder is self-contained regarding content and figures.
-
-If you want to find HTML versions of the BitBake manuals on the web,

-Makefile
-========
-
-The Makefile processes manual directories to create HTML, PDF,
-tarballs, etc.  Details on how the Makefile work are documented
-inside the Makefile.  See that file for more information.
-
-To build a manual, you run the make command and pass it the name
-of the folder containing the manual's contents. 
-For example, the following command run from the documentation directory 
-creates an HTML and a PDF version of the BitBake User Manual.
-The DOC variable specifies the manual you are making:
-
-     $ make DOC=bitbake-user-manual
-
-template
-========
-Contains various templates, fonts, and some old PNG files.
-
-tools

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

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

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

-            BitBake first searches the current working directory for an

-            variable that is a space-delimited list of 'layer' directories.
-            Recall that if BitBake cannot find a <filename>bblayers.conf</filename>
-            file, then it is assumed the user has set the <filename>BBPATH</filename>

-            After parsing configuration files, BitBake uses its rudimentary
-            inheritance mechanism, which is through class files, to inherit
-            some standard classes.
-            BitBake parses a class when the inherit directive responsible

-                You need to be aware of how BitBake parses curly braces.
-                If a recipe uses a closing curly brace within the function and
-                the character has no leading spaces, BitBake produces a parsing
-                error.
-                If you use a pair of curly braces in a shell function, the
-                closing curly brace must not be located at the start of the line
-                without leading spaces.

-                Here is an example that causes BitBake to produce a parsing

-     fakeroot create_shar() {

-     }
-     EOF
-     }
-                </literallayout>
-                Writing the recipe this way avoids the error:
-                <literallayout class='monospaced'>
-     fakeroot create_shar() {
-         cat &lt;&lt; "EOF" &gt; ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh

-            During the configuration phase, BitBake will have set
-            <link linkend='var-BBFILES'><filename>BBFILES</filename></link>.
-            BitBake now uses it to construct a list of recipes to parse,
-            along with any append files (<filename>.bbappend</filename>)
-            to apply.
-            <filename>BBFILES</filename> is a space-separated list of
-            available files and supports wildcards.
-            An example would be:
-            <literallayout class='monospaced'>
-     BBFILES = "/path/to/bbfiles/*.bb /path/to/appends/*.bbappend"
-            </literallayout>
-            BitBake parses each recipe and append file located
-            with <filename>BBFILES</filename> and stores the values of
-            various variables into the datastore.
-            <note>
-                Append files are applied in the order they are encountered in
-                <filename>BBFILES</filename>.
-            </note>
-            For each file, a fresh copy of the base configuration is
-            made, then the recipe is parsed line by line.
-            Any inherit statements cause BitBake to find and
-            then parse class files (<filename>.bbclass</filename>)
-            using
-            <link linkend='var-BBPATH'><filename>BBPATH</filename></link>
-            as the search path.
-            Finally, BitBake parses in order any append files found in
-            <filename>BBFILES</filename>.
-        </para>
-
-        <para>
-            One common convention is to use the recipe filename to define
-            pieces of metadata.
-            For example, in <filename>bitbake.conf</filename> the recipe
-            name and version are used to set the variables
-            <link linkend='var-PN'><filename>PN</filename></link> and
-            <link linkend='var-PV'><filename>PV</filename></link>:
-            <literallayout class='monospaced'>
-     PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE'),d)[0] or 'defaultpkgname'}"
-     PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE'),d)[1] or '1.0'}"
-            </literallayout>
-            In this example, a recipe called "something_1.2.3.bb" would set
-            <filename>PN</filename> to "something" and
-            <filename>PV</filename> to "1.2.3".
-        </para>
-
-        <para>
-            By the time parsing is complete for a recipe, BitBake
-            has a list of tasks that the recipe defines and a set of
-            data consisting of keys and values as well as
-            dependency information about the tasks.
-        </para>
-
-        <para>
-            BitBake does not need all of this information.
-            It only needs a small subset of the information to make
-            decisions about the recipe.
-            Consequently, BitBake caches the values in which it is
-            interested and does not store the rest of the information.
-            Experience has shown it is faster to re-parse the metadata than to
-            try and write it out to the disk and then reload it.
-        </para>
-
-        <para>
-            Where possible, subsequent BitBake commands reuse this cache of
-            recipe information.
-            The validity of this cache is determined by first computing a
-            checksum of the base configuration data (see
-            <link linkend='var-BB_HASHCONFIG_WHITELIST'><filename>BB_HASHCONFIG_WHITELIST</filename></link>)
-            and then checking if the checksum matches.
-            If that checksum matches what is in the cache and the recipe
-            and class files have not changed, Bitbake is able to use
-            the cache.
-            BitBake then reloads the cached information about the recipe
-            instead of reparsing it from scratch.

-            Recipe file collections exist to allow the user to
-            have multiple repositories of
-            <filename>.bb</filename> files that contain the same
-            exact package.
-            For example, one could easily use them to make one's
-            own local copy of an upstream repository, but with
-            custom modifications that one does not want upstream.
-            Here is an example:

-                The layers mechanism is now the preferred method of collecting

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

-            Assuming BitBake has been instructed to execute a target
-            and that all the recipe files have been parsed, BitBake
-            starts to figure out how to build the target.
-            BitBake looks through the <filename>PROVIDES</filename> list
-            for each of the recipes.
-            A <filename>PROVIDES</filename> list is the list of names by which
-            the recipe can be known.
-            Each recipe's <filename>PROVIDES</filename> list is created
-            implicitly through the recipe's
-            <link linkend='var-PN'><filename>PN</filename></link> variable
-            and explicitly through the recipe's
-            <link linkend='var-PROVIDES'><filename>PROVIDES</filename></link>
-            variable, which is optional.
-        </para>
-
-        <para>
-            When a recipe uses <filename>PROVIDES</filename>, that recipe's
-            functionality can be found under an alternative name or names other
-            than the implicit <filename>PN</filename> name.
-            As an example, suppose a recipe named <filename>keyboard_1.0.bb</filename>
-            contained the following:
-            <literallayout class='monospaced'>
-     PROVIDES += "fullkeyboard"
-            </literallayout>
-            The <filename>PROVIDES</filename> list for this recipe becomes
-            "keyboard", which is implicit, and "fullkeyboard", which is explicit.
-            Consequently, the functionality found in
-            <filename>keyboard_1.0.bb</filename> can be found under two
-            different names.

-            The <filename>PROVIDES</filename> list is only part of the solution
-            for figuring out a target's recipes.
-            Because targets might have multiple providers, BitBake needs
-            to prioritize providers by determining provider preferences.
-        </para>
-
-        <para>
-            A common example in which a target has multiple providers
-            is "virtual/kernel", which is on the
-            <filename>PROVIDES</filename> list for each kernel recipe.
-            Each machine often selects the best kernel provider by using a

-     PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"

-            Bitbake iterates through each target it needs to build and

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

-            variable.
-        </para>

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

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

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

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

-            near the end of this manual.
-            At a basic level, it is sufficient to know that BitBake uses the

-            Based on the generated list of providers and the dependency information,
-            BitBake can now calculate exactly what tasks it needs to run and in what
-            order it needs to run them.
-            The
-            "<link linkend='executing-tasks'>Executing Tasks</link>" section has more

-
-        <para>
-            The build now starts with BitBake forking off threads up to the limit set in the
-            <link linkend='var-BB_NUMBER_THREADS'><filename>BB_NUMBER_THREADS</filename></link>
-            variable.
-            BitBake continues to fork threads as long as there are tasks ready to run,
-            those tasks have all their dependencies met, and the thread threshold has not been
-            exceeded.
-        </para>

-        <para>
-            It is worth noting that you can greatly speed up the build time by properly setting

-        <para>
-            As each task completes, a timestamp is written to the directory specified by the
-            <link linkend='var-STAMP'><filename>STAMP</filename></link> variable.
-            On subsequent runs, BitBake looks in the build directory within
-            <filename>tmp/stamps</filename> and does not rerun
-            tasks that are already completed unless a timestamp is found to be invalid.
-            Currently, invalid timestamps are only considered on a per
-            recipe file basis.
-            So, for example, if the configure stamp has a timestamp greater than the
-            compile timestamp for a given target, then the compile task would rerun.
-            Running the compile task again, however, has no effect on other providers
-            that depend on that target.
-        </para>
-
-        <para>
-            The exact format of the stamps is partly configurable.
-            In modern versions of BitBake, a hash is appended to the
-            stamp so that if the configuration changes, the stamp becomes
-            invalid and the task is automatically rerun.
-            This hash, or signature used, is governed by the signature policy
-            that is configured (see the
-            "<link linkend='checksums'>Checksums (Signatures)</link>"
-            section for information).
-            It is also possible to append extra metadata to the stamp using
-            the "stamp-extra-info" task flag.
-            For example, OpenEmbedded uses this flag to make some tasks machine-specific.
-        </para>
-
-        <note>
-            Some tasks are marked as "nostamp" tasks.
-            No timestamp file is created when these tasks are run.

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

-
-        <para>
-            For Python tasks, BitBake executes the task internally and logs
-            information to the controlling terminal.
-            Future versions of BitBake will write the functions to files
-            similar to the way shell tasks are handled.
-            Logging will be handled in a way similar to shell tasks as well.
-        </para>
-
-        <para>
-            The order in which BitBake runs the tasks is controlled by its

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

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

-            BitBake first calls the function defined by the

-            variable with a list of tasks and corresponding

-            Next, for each of the tasks that were returned as possibilities,

-
-    <para>
-        BitBake's fetch module is a standalone piece of library code
-        that deals with the intricacies of downloading source code
-        and files from remote systems.
-        Fetching source code is one of the cornerstones of building software.
-        As such, this module forms an important part of BitBake.
-    </para>
-
-    <para>
-        The current fetch module is called "fetch2" and refers to the
-        fact that it is the second major version of the API.
-        The original version is obsolete and has been removed from the codebase.
-        Thus, in all cases, "fetch" refers to "fetch2" in this
-        manual.
-    </para>

-        <title>The Download (Fetch)</title>
-
-        <para>
-            BitBake takes several steps when fetching source code or files.
-            The fetcher codebase deals with two distinct processes in order:
-            obtaining the files from somewhere (cached or otherwise)
-            and then unpacking those files into a specific location and
-            perhaps in a specific way.
-            Getting and unpacking the files is often optionally followed
-            by patching.
-            Patching, however, is not covered by this module.
-        </para>
-
-        <para>
-            The code to execute the first part of this process, a fetch,
-            looks something like the following:
-            <literallayout class='monospaced'>
-     src_uri = (d.getVar('SRC_URI', True) or "").split()
-     fetcher = bb.fetch2.Fetch(src_uri, d)
-     fetcher.download()
-            </literallayout>
-            This code sets up an instance of the fetch class.
-            The instance uses a space-separated list of URLs from the
-            <link linkend='var-SRC_URI'><filename>SRC_URI</filename></link>
-            variable and then calls the <filename>download</filename>
-            method to download the files.
-        </para>
-
-        <para>
-            The instantiation of the fetch class is usually followed by:
-            <literallayout class='monospaced'>
-     rootdir = l.getVar('WORKDIR', True)
-     fetcher.unpack(rootdir)
-            </literallayout>
-            This code unpacks the downloaded files to the
-            specified by <filename>WORKDIR</filename>.
-            <note>
-                For convenience, the naming in these examples matches
-                the variables used by OpenEmbedded.
-                If you want to see the above code in action, examine
-                the OpenEmbedded class file <filename>base.bbclass</filename>.
-            </note>
-            The <filename>SRC_URI</filename> and <filename>WORKDIR</filename>
-            variables are not hardcoded into the fetcher, since those fetcher
-            methods can be (and are) called with different variable names.
-            In OpenEmbedded for example, the shared state (sstate) code uses
-            the fetch module to fetch the sstate files.
-        </para>
-
-        <para>
-            When the <filename>download()</filename> method is called,
-            BitBake tries to resolve the URLs by looking for source files
-            in a specific search order:
-            <itemizedlist>
-                <listitem><para><emphasis>Pre-mirror Sites:</emphasis>
-                    BitBake first uses pre-mirrors to try and find source files.
-                    These locations are defined using the
-                    <link linkend='var-PREMIRRORS'><filename>PREMIRRORS</filename></link>
-                    variable.
-                    </para></listitem>
-                <listitem><para><emphasis>Source URI:</emphasis>
-                    If pre-mirrors fail, BitBake uses the original URL (e.g from
-                    <filename>SRC_URI</filename>).
-                    </para></listitem>
-                <listitem><para><emphasis>Mirror Sites:</emphasis>
-                    If fetch failures occur, BitBake next uses mirror locations as
-                    defined by the
-                    <link linkend='var-MIRRORS'><filename>MIRRORS</filename></link>
-                    variable.
-                    </para></listitem>
-            </itemizedlist>
-        </para>
-
-        <para>
-            For each URL passed to the fetcher, the fetcher
-            calls the submodule that handles that particular URL type.
-            This behavior can be the source of some confusion when you
-            are providing URLs for the <filename>SRC_URI</filename>
-            variable.
-            Consider the following two URLs:
-            <literallayout class='monospaced'>
-     http://git.yoctoproject.org/git/poky;protocol=git
-     git://git.yoctoproject.org/git/poky;protocol=http
-            </literallayout>
-            In the former case, the URL is passed to the
-            <filename>wget</filename> fetcher, which does not
-            understand "git".
-            Therefore, the latter case is the correct form since the
-            Git fetcher does know how to use HTTP as a transport.
-        </para>
-
-        <para>
-            Here are some examples that show commonly used mirror
-            definitions:
-            <literallayout class='monospaced'>
-     PREMIRRORS ?= "\
-         bzr://.*/.*   http://somemirror.org/sources/ \n \

-         hg://.*/.*    http://somemirror.org/sources/ \n \
-         osc://.*/.*   http://somemirror.org/sources/ \n \
-         p4://.*/.*    http://somemirror.org/sources/ \n \
-         svn://.*/.*   http://somemirror.org/sources/ \n"
-
-     MIRRORS =+ "\
-         ftp://.*/.*      http://somemirror.org/sources/ \n \
-         http://.*/.*     http://somemirror.org/sources/ \n \
-         https://.*/.*    http://somemirror.org/sources/ \n"
-            </literallayout>
-            It is useful to note that BitBake supports
-            cross-URLs.
-            It is possible to mirror a Git repository on an HTTP
-            server as a tarball.
-            This is what the <filename>git://</filename> mapping in
-            the previous example does.
-        </para>
-
-        <para>
-            Since network accesses are slow, Bitbake maintains a
-            cache of files downloaded from the network.
-            Any source files that are not local (i.e.
-            downloaded from the Internet) are placed into the download
-            directory, which is specified by the
-            <link linkend='var-DL_DIR'><filename>DL_DIR</filename></link>
-            variable.
-        </para>
-
-        <para>
-            File integrity is of key importance for reproducing builds.
-            For non-local archive downloads, the fetcher code can verify
-            SHA-256 and MD5 checksums to ensure the archives have been
-            downloaded correctly.
-            You can specify these checksums by using the
-            <filename>SRC_URI</filename> variable with the appropriate
-            varflags as follows:
-            <literallayout class='monospaced'>
-     SRC_URI[md5sum] = "value"
-     SRC_URI[sha256sum] = "value"
-            </literallayout>
-            You can also specify the checksums as parameters on the
-            <filename>SRC_URI</filename> as shown below:
-            <literallayout class='monospaced'>
-     SRC_URI = "http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d"
-            </literallayout>
-            If multiple URIs exist, you can specify the checksums either
-            directly as in the previous example, or you can name the URLs.
-            The following syntax shows how you name the URIs:
-            <literallayout class='monospaced'>
-     SRC_URI = "http://example.com/foobar.tar.bz2;name=foo"
-     SRC_URI[foo.md5sum] = 4a8e0f237e961fd7785d19d07fdb994d
-            </literallayout>
-            After a file has been downloaded and has had its checksum checked,
-            a ".done" stamp is placed in <filename>DL_DIR</filename>.
-            BitBake uses this stamp during subsequent builds to avoid
-            downloading or comparing a checksum for the file again.
-            <note>
-                It is assumed that local storage is safe from data corruption.
-                If this were not the case, there would be bigger issues to worry about.
-            </note>
-        </para>
-
-        <para>
-            If
-            <link linkend='var-BB_STRICT_CHECKSUM'><filename>BB_STRICT_CHECKSUM</filename></link>
-            is set, any download without a checksum triggers an
-            error message.
-            The
-            <link linkend='var-BB_NO_NETWORK'><filename>BB_NO_NETWORK</filename></link>
-            variable can be used to make any attempted network access a fatal
-            error, which is useful for checking that mirrors are complete
-            as well as other things.

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

-                    Controls whether the URL components are unpacked.
-                    If set to "1", which is the default, the components
-                    are unpacked.
-                    If set to "0", the unpack stage leaves the file alone.
-                    This parameter is useful when you want an archive to be
-                    copied in and not be unpacked.

-            As mentioned, the Git fetcher has its own unpack method that
-            is optimized to work with Git trees.
-            Basically, this method works by cloning the tree into the final
-            directory.
-            The process is completed using references so that there is
-            only one central copy of the Git metadata needed.

-        <title>Fetchers</title>
-
-        <para>
-            As mentioned earlier, the URL prefix determines which
-            fetcher submodule BitBake uses.
-            Each submodule can support different URL parameters,
-            which are described in the following sections.

-                <filename>file://</filename>.
-                The filename you specify within the URL can be
-                either an absolute or relative path to a file.
-                If the filename is relative, the contents of the
-                <link linkend='var-FILESPATH'><filename>FILESPATH</filename></link>
-                variable is used in the same way
-                <filename>PATH</filename> is used to find executables.
-                Failing that,
-                <link linkend='var-FILESDIR'><filename>FILESDIR</filename></link>
-                is used to find the appropriate relative file.
-                <note>
-                    <filename>FILESDIR</filename> is deprecated and can

-                    Because <filename>FILESDIR</filename> is likely to be

-                source control system.

-                <link linkend='var-GITDIR'><filename>GITDIR</filename></link>,
-                which is usually <filename>DL_DIR/git2</filename>.
-                This bare clone is then cloned into the work directory during the
-                unpack stage when a specific tree is checked out.
-                This is done using alternates and by reference to
-                minimize the amount of duplicate data on the disk and
-                make the unpack process fast.

-                        In this case, the source mirror tarball is done per

-                        Rebasing the upstream Git repository could cause the

-                        This option reminds the fetcher to preserve the local cache

-                        As far as Git is concerned, the "tag" parameter behaves

-                The fetcher uses the <filename>rcleartool</filename> or

-                By default, the fetcher creates a configuration specification.
-                If you want this specification written to an area other than the default,
-                use the <filename>CCASE_CUSTOM_CONFIG_SPEC</filename> variable
-                in your recipe to define where the specification is written.
-                <note>
-                    the <filename>SRCREV</filename> loses its functionality if you
-                    specify this variable.
-                    However, <filename>SRCREV</filename> is still used to label the
-                    archive after a fetch even though it does not define what is

-
-        <para>
-            First, you need to be sure that you can run BitBake.
-            Set your working directory to where your local BitBake
-            files are and run the following command:
-            <literallayout class='monospaced'>
-     $ ./bin/bitbake --version
-     BitBake Build Tool Core version 1.23.0, bitbake version 1.23.0
-            </literallayout>
-            The console output tells you what version you are running.
-        </para>
-
-        <para>
-            The recommended method to run BitBake is from a directory of your
-            choice.
-            To be able to run BitBake from any directory, you need to add the
-            executable binary to your binary to your shell's environment
-            <filename>PATH</filename> variable.
-            First, look at your current <filename>PATH</filename> variable
-            by entering the following:
-            <literallayout class='monospaced'>
-     $ echo $PATH
-            </literallayout>
-            Next, add the directory location for the BitBake binary to the
-            <filename>PATH</filename>.
-            Here is an example that adds the
-            <filename>/home/scott-lenovo/bitbake/bin</filename> directory
-            to the front of the <filename>PATH</filename> variable:
-            <literallayout class='monospaced'>
-     $ export PATH=/home/scott-lenovo/bitbake/bin:$PATH
-            </literallayout>
-            You should now be able to enter the <filename>bitbake</filename>
-            command from the command line while working from any directory.

-            The overall goal of this exercise is to build a

-            Because this is how modern projects such as OpenEmbedded and

-            The example progresses by adding pieces to the build to

-            As stated earlier, the goal of this example
-            is to eventually compile "Hello World".
-            However, it is unknown what BitBake needs and what you have
-            to provide in order to achieve that goal.
-            Recall that BitBake utilizes three types of metadata files:
-            <link linkend='configuration-files'>Configuration Files</link>,
-            <link linkend='classes'>Classes</link>, and
-            <link linkend='recipes'>Recipes</link>.
-            But where do they go?
-            How does BitBake find them?
-            BitBake's error messaging helps you answer these types of questions
-            and helps you better understand exactly what is going on.

-                First, set up a directory for the "Hello World" project.
-                Here is how you can do so in your home directory:
-                <literallayout class='monospaced'>
-     $ mkdir ~/hello
-     $ cd ~/hello

-                This is the directory that BitBake will use to do all of
-                its work.
-                You can use this directory to keep all the metafiles needed
-                by BitBake.
-                Having a project directory is a good way to isolate your
-                project.

-                    After the first execution, re-running

-                    using that same <filename>bitbake</filename> command,
-                    BitBake notices the stamp and therefore determines

-                    or run <filename>bitbake -c clean printhello</filename>
-                    and then re-run the build, the "Hello, World!" message will

-        Welcome to the BitBake User Manual.
-        This manual provides information on the BitBake tool.
-        The information attempts to be as independent as possible regarding
-        systems that use BitBake, such as OpenEmbedded and the
-        Yocto Project.
-        In some cases, scenarios or examples within the context of
-        a build system are used in the manual to help with understanding.
-        For these cases, the manual clearly states the context.

-            Fundamentally, BitBake is a generic task execution
-            engine that allows shell and Python tasks to be run
-            efficiently and in parallel while working within
-            complex inter-task dependency constraints.
-            One of BitBake's main users, OpenEmbedded, takes this core
-            and builds embedded Linux software stacks using
-            a task-oriented approach.

-            Conceptually, BitBake is similar to GNU Make in

-        <title>History and Goals</title>
-
-        <para>
-            BitBake was originally a part of the OpenEmbedded project.
-            It was inspired by the Portage package management system
-            used by the Gentoo Linux distribution.
-            On December 7, 2004, OpenEmbedded project team member
-            Chris Larson split the project into two distinct pieces:
-            <itemizedlist>
-                <listitem><para>BitBake, a generic task executor</para></listitem>
-                <listitem><para>OpenEmbedded, a metadata set utilized by
-                    BitBake</para></listitem>
-            </itemizedlist>
-            Today, BitBake is the primary basis of the
-            <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink>
-            project, which is being used to build and maintain Linux
-            distributions such as the
-            <ulink url='http://www.angstrom-distribution.org/'>Angstrom Distribution</ulink>,
-            and which is also being used as the build tool for Linux projects
-            such as the
-            <ulink url='http://www.yoctoproject.org'>Yocto Project</ulink>.
-        </para>
-
-        <para>
-            Prior to BitBake, no other build tool adequately met the needs of
-            an aspiring embedded Linux distribution.
-            All of the build systems used by traditional desktop Linux
-            distributions lacked important functionality, and none of the
-            ad hoc Buildroot-based systems, prevalent in the
-            embedded space, were scalable or maintainable.

-            BitBake satisfies all the original requirements and many more
-            with extensions being made to the basic functionality to
-            reflect the additional requirements.
-            Flexibility and power have always been the priorities.
-            BitBake is highly extensible and supports embedded Python code and
-            execution of any arbitrary tasks.

-
-        <para>
-            BitBake is a program written in the Python language.
-            At the highest level, BitBake interprets metadata, decides
-            what tasks are required to run, and executes those tasks.
-            Similar to GNU Make, BitBake controls how software is
-            built.
-            GNU Make achieves its control through "makefiles", while
-            BitBake uses "recipes".
-        </para>
-
-        <para>
-            BitBake extends the capabilities of a simple
-            tool like GNU Make by allowing for the definition of much more
-            complex tasks, such as assembling entire embedded Linux
-            distributions.

-            The remainder of this section introduces several concepts

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

-                Within the context of BitBake, or any project utilizing BitBake
-                as its build system, files with the <filename>.bb</filename>
-                extension are referred to as recipes.
-                <note>
-                    The term "package" is also commonly used to describe recipes.
-                    However, since the same word is used to describe packaged
-                    output from a project, it is best to maintain a single
-                    descriptive term - "recipes".
-                    Put another way, a single "recipe" file is quite capable
-                    of generating a number of related but separately installable
-                    "packages".
-                    In fact, that ability is fairly common.

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

-                Append files, which are files that have the

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

-            </para>
-
-            <para>
-                When you name an append file, you can use the
-                wildcard character (%) to allow for matching recipe names.
-                For example, suppose you have an append file named
-                as follows:
-                <literallayout class='monospaced'>

-                version of the recipe.
-                So, the append file would match the following recipe names:

-                <filename>busybox_1.3.0.bb</filename>, the append name would not
-                match.
-                However, if you named the append file
-                <filename>busybox_1.%.bbappend</filename>, then you would have a match.
-            </para>
-
-            <para>
-                In the most general case, you could name the append file something as

-                    Using Git to clone the BitBake source code repository

-                    Cloning the repository makes it easy to get bug fixes
-                    and have access to stable branches and the master
-                    branch.
-                    Once you have cloned BitBake, you should use
-                    the latest stable
-                    branch for development since the master branch is for
-                    BitBake development and might contain less stable changes.

-                    directory called <filename>bitbake</filename>.
-                    Alternatively, you can

-                    To stop depending on common depends, use the "-I" depend

-                    Leaving this information out can produce more readable graphs.
-                    This way, you can remove from the graph
-                    <filename>DEPENDS</filename> from inherited classes

-                    <literallayout class='monospaced'>
-     $ bitbake -g foo
-
-     $ bitbake -g -I virtual/kernel -I eglibc foo

-   Generic XHTML / DocBook XHTML CSS Stylesheet.
-
-   Browser wrangling and typographic design by
-      Oyvind Kolas / pippin@gimp.org
-
-   Customised for Poky by
-      Matthew Allum / mallum@o-hand.com
-
-   Thanks to:
-     Liam R. E. Quin
-     William Skaggs
-     Jakub Steiner
-
-   Structure
-   ---------
-
-   The stylesheet is divided into the following sections:
-
-       Positioning
-          Margins, paddings, width, font-size, clearing.
-       Decorations
-          Borders, style
-       Colors
-          Colors
-       Graphics
-          Graphical backgrounds
-       Nasty IE tweaks
-          Workarounds needed to make it work in internet explorer,
-          currently makes the stylesheet non validating, but up until
-          this point it is validating.
-       Mozilla extensions
-          Transparency for footer
-	  Rounded corners on boxes

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

+        <title>Metadata</title>
+        <section>
+            <title>Description</title>
+            <itemizedlist>
+                <para>BitBake metadata can be classified into 3 major areas:</para>
+                <listitem>
+                    <para>Configuration Files</para>
+                </listitem>
+                <listitem>
+                    <para>.bb Files</para>
+                </listitem>
+                <listitem>
+                    <para>Classes</para>
+                </listitem>
+            </itemizedlist>
+            <para>What follows are a large number of examples of BitBake metadata.  Any syntax which isn't supported in any of the aforementioned areas will be documented as such.</para>
+            <section>
+                <title>Basic variable setting</title>
+                <para><screen><varname>VARIABLE</varname> = "value"</screen></para>
+                <para>In this example, <varname>VARIABLE</varname> is <literal>value</literal>.</para>
+            </section>
+            <section>
+                <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 its previous value. If <varname>A</varname> is unset prior to the above call, <varname>A</varname> will be set to <literal>aval</literal>.  Note that this assignment is immediate, so if there are multiple ?= assignments to a single variable, the first of those will be used.</para>
+            </section>
+            <section>
+                <title>Setting a weak default value (??=)</title>
+                <para><screen><varname>A</varname> ??= "somevalue"
+<varname>A</varname> ??= "someothervalue"</screen></para>
+                <para>If <varname>A</varname> is set before the above, it will retain that value.  If <varname>A</varname> is unset prior to the above, <varname>A</varname> will be set to <literal>someothervalue</literal>.  This is a lazy/weak assignment in that the assignment does not occur until the end of the parsing process, so that the last, rather than the first, ??= assignment to a given variable will be used. Any other setting of A using = or ?= will however override the value set with ??=</para>
+            </section>
+            <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>

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>

+<varname>TEST</varname> = "defaultvalue"

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

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

+
+            <para>The SRC_URI is normally used to tell BitBake which files to fetch. The next sections will describe the available fetchers and their options. Each fetcher honors a set of variables and per URI parameters separated by a <quote>;</quote> consisting of a key and a value. The semantics of the variables and parameters are defined by the fetcher. BitBake tries to have consistent semantics between the different fetchers.
+            </para>
+
+            <para>The overall fetch process is that first, fetches are attempted from PREMIRRORS. If those don't work, the original SRC_URI is attempted and if that fails, BitBake will fall back to MIRRORS. Cross urls are supported, so its possible to mirror a git repository on an http server as a tarball for example. Some example commonly used mirror definitions are:</para>

For non local archive downloads the code can verify sha256 and md5 checksums for the download to ensure the file has been downloaded correctly. These may be specified either in the form <varname>SRC_URI[md5sum]</varname> for the md5 checksum and <varname>SRC_URI[sha256sum]</varname> for the sha256 checksum or as parameters on the SRC_URI such as SRC_URI="http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d". If <varname>BB_STRICT_CHECKSUM</varname> is set, any download without a checksum will trigger an error message. In cases where multiple files are listed in SRC_URI, the name parameter is used assign names to the urls and these are then specified in the checksums in the form SRC_URI[name.sha256sum].</para>

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

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

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

+                    <para>Note that the bitbake command, when not using --buildfile, accepts a <varname>PROVIDER</varname>, not a filename or anything else.  By default, a .bb generally PROVIDES its packagename, packagename-version, and packagename-version-revision.</para>

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

+                <para>As you may have seen in the usage information, or in the information about .bb files, the <varname>BBFILES</varname> variable is how the BitBake tool locates its files.  This variable is a space separated list of files that are available, and supports wildcards.

+                <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, set to a component of the .bb filename by default.</para>

+                    <para>This example shows the usage of the <varname>PROVIDES</varname> variable, which allows a given .bb to specify what functionality it provides.</para>

+                    <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 preference for the default selected version.  In addition, the user can specify their preferred 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.

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

-BitBake SFTP Fetch implementation
-
-Class for fetching files via SFTP. It tries to adhere to the (now
-expired) IETF Internet Draft for "Uniform Resource Identifier (URI)
-Scheme for Secure File Transfer Protocol (SFTP) and Secure Shell
-(SSH)" (SECSH URI).
-
-It uses SFTP (as to adhere to the SECSH URI specification). It only
-supports key based authentication, not password. This class, unlike
-the SSH fetcher, does not support fetching a directory tree from the
-remote.
-
-  http://tools.ietf.org/html/draft-ietf-secsh-scp-sftp-ssh-uri-04
-  https://www.iana.org/assignments/uri-schemes/prov/sftp
-  https://tools.ietf.org/html/draft-ietf-secsh-filexfer-13
-
-Please note that '/' is used as host path seperator, and not ":"
-as you may be used to from the scp/sftp commands. You can use a
-~ (tilde) to specify a path relative to your home directory.
-(The /~user/ syntax, for specyfing a path relative to another
-user's home directory is not supported.) Note that the tilde must
-still follow the host path seperator ("/"). See exampels below.
-
-Example SRC_URIs:
-
-SRC_URI = "sftp://host.example.com/dir/path.file.txt"
-
-A path relative to your home directory.
-
-SRC_URI = "sftp://host.example.com/~/dir/path.file.txt"
-
-You can also specify a username (specyfing password in the
-URI is not supported, use SSH keys to authenticate):
-
-SRC_URI = "sftp://user@host.example.com/dir/path.file.txt"
