+# DESCRIPTION
+# This script runs BB_CMD (typically building core-image-sato) for all
+# combincations of BB_RANGE and PM_RANGE values. It saves off all the console
+# logs, the buildstats directories, and creates a bb-pm-runtime.dat file which
+# can be used to postprocess the results with a plotting tool, spreadsheet, etc.
+# Before running this script, it is recommended that you pre-download all the
+# necessary sources by performing the BB_CMD once manually. It is also a good
+# idea to disable cron to avoid runtime variations caused by things like the
+# locate process. Be sure to sanitize the dat file prior to post-processing as
+# it may contain error messages or bad runs that should be removed.

+# DESCRIPTION
+# This script is intended to be used in conjunction with "git bisect run"
+# in order to find regressions in build time, however it can also be used
+# independently. It cleans out the build output directories, runs a
+# specified worker script (an example is test_build_time_worker.sh) under
+# TIME(1), logs the results to TEST_LOGDIR (default /tmp) and returns a
+# value telling "git bisect run" whether the build time is good (under
+# the specified threshold) or bad (over it). There is also a tolerance
+# option but it is not particularly useful as it only subtracts the
+# tolerance from the given threshold and uses it as the actual threshold.
+#
+# It is also capable of taking a file listing git revision hashes to be
+# test-applied to the repository in order to get past build failures that
+# would otherwise cause certain revisions to have to be skipped; if a
+# revision does not apply cleanly then the script assumes it does not
+# need to be applied and ignores it.
+#
+# Please see the help output (syntax below) for some important setup
+# instructions.
+#
+# AUTHORS
+# Paul Eggleton <paul.eggleton@linux.intel.com>

+# DESCRIPTION
+# This module implements the templating engine used by 'yocto-bsp' to
+# create BSPs.  The BSP templates are simply the set of files expected
+# to appear in a generated BSP, marked up with a small set of tags
+# used to customize the output.  The engine parses through the
+# templates and generates a Python program containing all the logic
+# and input elements needed to display and retrieve BSP-specific
+# information from the user.  The resulting program uses those results
+# to generate the final BSP files.
+#

+DESCRIPTION
+    This command creates a Yocto BSP based on the specified
+    parameters.  The new BSP will be a new Yocto BSP layer contained
+    by default within the top-level directory specified as
+    'meta-bsp-name'.  The -o option can be used to place the BSP layer
+    in a directory with a different name and location.
+
+    The value of the 'karch' parameter determines the set of files
+    that will be generated for the BSP, along with the specific set of
+    'properties' that will be used to fill out the BSP-specific
+    portions of the BSP.  The possible values for the 'karch' paramter
+    can be listed via 'yocto-bsp list karch'.
+
+    The BSP-specific properties that define the values that will be
+    used to generate a particular BSP can be specified on the
+    command-line using the -i option and supplying a JSON object
+    consisting of the set of name:value pairs needed by the BSP.
+
+    If the -i option is not used, the user will be interactively
+    prompted for each of the required property values, which will then
+    be used as values for BSP generation.
+
+    The set of properties available for a given architecture can be
+    listed using the 'yocto-bsp list' command.
+
+    Specifying -c causes the Python code generated and executed to
+    create the BSP to be dumped to the 'bspgen.out' file in the
+    current directory, and is useful for debugging.
+
+    NOTE: Once created, you should add your new layer to your
+    bblayers.conf file in order for it to be subsequently seen and
+    modified by the yocto-kernel tool.
+
+    For example, assuming your poky repo is at /path/to/poky, your new
+    BSP layer is at /path/to/poky/meta-mybsp, and your build directory

+DESCRIPTION
+    This command enumerates the complete set of possible values for a
+    specified option or property needed by the BSP creation process.
+
+    The first form enumerates all the possible values that exist and
+    can be specified for the 'karch' parameter to the 'yocto bsp
+    create' command.  Example output for the 'list karch' command:
+
+    $ yocto-bsp list karch
+    Architectures available:
+        arm
+        powerpc
+        i386
+        mips
+        mips64
+        x86_64
+        qemu
+
+    The second form enumerates all the possible properties that exist
+    and must have values specified for them in the 'yocto bsp create'
+    command for the given 'karch'.  This command is mainly meant to
+    allow the development user interface alternatives to the default
+    text-based prompting interface.  If the -o option is specified,
+    the list of properties, in addition to being displayed, will be
+    written to the specified file as a JSON object.  In this case, the
+    object will consist of the set of name:value pairs corresponding
+    to the (possibly nested) dictionary of properties defined by the
+    input statements used by the BSP.  Some example output for the
+    'list properties' command:
+
+    $ yocto-bsp list arm properties
+    "touchscreen" : {
+        "msg" : Does your BSP have a touchscreen? (y/N)
+        "default" : n
+        "type" : boolean
+    }

+        "type" : edit
+        "prio" : 40
+    }
+    "kernel_choice" : {
+        "prio" : 10
+        "default" : linux-yocto_3.2
+        "depends-on" : use_default_kernel
+        "depends-on-val" : n
+        "msg" : Please choose the kernel to use in this BSP =>
+        "type" : choicelist
+        "gen" : bsp.kernel.kernels
+    }
+    "if kernel_choice == "linux-yocto_3.0":" : {
+        "base_kbranch_linux_yocto_3_0" : {
+            "prio" : 20
+            "default" : yocto/standard
+            "depends-on" : new_kbranch_linux_yocto_3_0
+            "depends-on-val" : y
+            "msg" : Please choose a machine branch to base this BSP on =>
+            "type" : choicelist
+            "gen" : bsp.kernel.all_branches
+    }
+    .
+    .
+    .
+
+    Each entry in the output consists of the name of the input element
+    e.g. "touchscreen", followed by the properties defined for that
+    element enclosed in braces.  This information should provide
+    sufficient information to create a complete user interface with.
+    Two features of the scheme provide for conditional input.  First,
+    if a Python "if" statement appears in place of an input element
+    name, the set of enclosed input elements apply and should be
+    presented to the user only if the 'if' statement evaluates to
+    true.  The test in the if statement will always reference another
+    input element in the list, which means that the element being
+    tested should be presented to the user before the elements
+    enclosed by the if block.  Secondly, in a similar way, some
+    elements contain "depends-on" and depends-on-val" tags, which mean
+    that the affected input element should only be presented to the
+    user if the element it depends on has already been presented to
+    the user and the user has selected the specified value for that
+    element.
+
+    The third form enumerates all the possible values that exist and
+    can be specified for any of the enumerable properties of the given
+    'karch' in the 'yocto bsp create' command.  If the -o option is
+    specified, the list of values for the given property, in addition
+    to being displayed, will be written to the specified file as a
+    JSON object.  In this case, the object will consist of the set of
+    name:value pairs corresponding to the array of property values
+    associated with the property.

+    the set of enclosed input elements apply and should be presented
+    to the user only if the 'if' statement evaluates to true.  The
+    test in the if statement will always reference another input
+    element in the list, which means that the element being tested
+    should be presented to the user before the elements enclosed by
+    the if block.  Secondly, in a similar way, some elements contain
+    "depends-on" and depends-on-val" tags, which mean that the
+    affected input element should only be presented to the user if the
+    element it depends on has already been presented to the user and
+    the user has selected the specified value for that element.
+
+    The second form enumerates all the possible values that exist and
+    can be specified for any of the enumerable properties in the
+    'yocto-layer create' command.  If the -o option is specified, the
+    list of values for the given property, in addition to being
+    displayed, will be written to the specified file as a JSON object.
+    In this case, the object will consist of the set of name:value
+    pairs corresponding to the array of property values associated
+    with the property.
+
+    $ yocto-layer list property layer_priority
+     [no output - layer_priority is a text field that has no enumerable values]
+
+    The second form as well is meant mainly for developers of
+    alternative interfaces - it allows the developer to fetch the
+    possible values for a given input element on-demand.  This
+    on-demand capability is especially valuable for elements that
+    require relatively expensive remote operations to fulfill, such as
+    the example that returns the set of branches available in a remote
+    git tree above.

+
+Patches
+=======
+
+Please submit any patches against this BSP to the Yocto mailing list
+(yocto@yoctoproject.org) and cc: the maintainer:
+
+Maintainer: XXX YYYYYY <xxx.yyyyyy@zzzzz.com>
+
+Please see the meta-xxxx/MAINTAINERS file for more details.
+
+
+Table of Contents
+=================
+
+  I. Building the meta-{{=machine}} BSP layer
+ II. Booting the images in /binary
+
+
+I. Building the meta-{{=machine}} BSP layer
+========================================
+
+--- replace with specific instructions for your layer ---
+
+In order to build an image with BSP support for a given release, you
+need to download the corresponding BSP tarball from the 'Board Support
+Package (BSP) Downloads' page of the Yocto Project website.
+
+Having done that, and assuming you extracted the BSP tarball contents
+at the top-level of your yocto build tree, you can build a
+{{=machine}} image by adding the location of the meta-{{=machine}}
+layer to bblayers.conf, along with any other layers needed (to access
+common metadata shared between BSPs) e.g.:
+
+  yocto/meta-xxxx \
+  yocto/meta-xxxx/meta-{{=machine}} \
+
+To enable the {{=machine}} layer, add the {{=machine}} MACHINE to local.conf:
+
+  MACHINE ?= "{{=machine}}"
+
+You should then be able to build a {{=machine}} image as such:
+
+  $ source oe-init-build-env
+  $ bitbake core-image-sato
+
+At the end of a successful build, you should have a live image that
+you can boot from a USB flash drive (see instructions on how to do
+that below, in the section 'Booting the images from /binary').
+
+As an alternative to downloading the BSP tarball, you can also work
+directly from the meta-xxxx git repository.  For each BSP in the
+'meta-xxxx' repository, there are multiple branches, one corresponding
+to each major release starting with 'laverne' (0.90), in addition to
+the latest code which tracks the current master (note that not all
+BSPs are present in every release).  Instead of extracting a BSP
+tarball at the top level of your yocto build tree, you can
+equivalently check out the appropriate branch from the meta-xxxx
+repository at the same location.
+
+
+II. Booting the images in /binary
+=================================
+
+--- replace with specific instructions for your platform ---
+
+This BSP contains bootable live images, which can be used to directly
+boot Yocto off of a USB flash drive.
+
+Under Linux, insert a USB flash drive.  Assuming the USB flash drive
+takes device /dev/sdf, use dd to copy the live image to it.  For
+example:
+
+# dd if=core-image-sato-{{=machine}}-20101207053738.hddimg of=/dev/sdf
+# sync
+# eject /dev/sdf
+
+This should give you a bootable USB flash device.  Insert the device
+into a bootable USB socket on the target, and power on.  This should
+result in a system booted to the Sato graphical desktop.
+
+If you want a terminal, use the arrows at the top of the UI to move to
+different pages of available applications, one of which is named
+'Terminal'.  Clicking that should give you a root terminal.
+
+If you want to ssh into the system, you can use the root terminal to
+ifconfig the IP address and use that to ssh in.  The root password is
+empty, so to log in type 'root' for the user name and hit 'Enter' at
+the Password prompt: and you should be in.
+
+----
+
+If you find you're getting corrupt images on the USB (it doesn't show
+the syslinux boot: prompt, or the boot: prompt contains strange
+characters), try doing this first:
+
+# dd if=/dev/zero of=/dev/sdf bs=1M count=512

+I. Adding the {{=layer_name}} layer to your build
+=================================================
+
+--- replace with specific instructions for the {{=layer_name}} layer ---
+
+In order to use this layer, you need to make the build system aware of
+it.
+
+Assuming the {{=layer_name}} layer exists at the top-level of your
+yocto build tree, you can add it to the build system by adding the
+location of the {{=layer_name}} layer to bblayers.conf, along with any
+other layers needed. e.g.:
+
+  BBLAYERS ?= " \
+    /path/to/yocto/meta \
+    /path/to/yocto/meta-yocto \
+    /path/to/yocto/meta-yocto-bsp \
+    /path/to/yocto/meta-{{=layer_name}} \
+    "
+
+
+II. Misc
+========
+
+--- replace with specific information about the {{=layer_name}} layer ---

+changes take place.

+
+    returnClassForVersion - Given a version number, return the matching
+                            handler class.  This does not return an
+                            instance of that class, however.
+
+    stringToVersion - Convert a string representation of a version number
+                      into the symbolic constant.
+
+    versionToString - Perform the reverse mapping.
+
+    versionFromFile - Read a kickstart file and determine the version of
+                      syntax it uses.  This requires the kickstart file to
+                      have a version= comment in it.

+
+DESCRIPTION
+    This command creates an OpenEmbedded image based on the 'OE
+    kickstart commands' found in the <wks file>.
+
+    In order to do this, wic needs to know the locations of the
+    various build artifacts required to build the image.
+
+    Users can explicitly specify the build artifact locations using
+    the -r, -b, -k, and -n options.  See below for details on where
+    the corresponding artifacts are typically found in a normal
+    OpenEmbedded build.
+
+    Alternatively, users can use the -e option to have 'wic' determine
+    those locations for a given image.  If the -e option is used, the
+    user needs to have set the appropriate MACHINE variable in
+    local.conf, and have sourced the build environment.
+
+    The -e option is used to specify the name of the image to use the
+    artifacts from e.g. core-image-sato.
+
+    The -r option is used to specify the path to the /rootfs dir to
+    use as the .wks rootfs source.
+
+    The -b option is used to specify the path to the dir containing
+    the boot artifacts (e.g. /EFI or /syslinux dirs) to use as the
+    .wks bootimg source.
+
+    The -k option is used to specify the path to the dir containing
+    the kernel to use in the .wks bootimg.
+
+    The -n option is used to specify the path to the native sysroot
+    containing the tools to use to build the image.
+
+    The -f option is used to build rootfs by running "bitbake <image>"
+
+    The -s option is used to skip the build check.  The build check is
+    a simple sanity check used to determine whether the user has
+    sourced the build environment so that the -e option can operate
+    correctly.  If the user has specified the build artifact locations
+    explicitly, 'wic' assumes the user knows what he or she is doing
+    and skips the build check.
+
+    The -D option is used to display debug information detailing
+    exactly what happens behind the scenes when a create request is
+    fulfilled (or not, as the case may be).  It enumerates and
+    displays the command sequence used, and should be included in any
+    bug report describing unexpected results.
+
+    When 'wic -e' is used, the locations for the build artifacts
+    values are determined by 'wic -e' from the output of the 'bitbake
+    -e' command given an image name e.g. 'core-image-minimal' and a
+    given machine set in local.conf.  In that case, the image is
+    created as if the following 'bitbake -e' variables were used:
+
+    -r:        IMAGE_ROOTFS
+    -k:        STAGING_KERNEL_DIR
+    -n:        STAGING_DIR_NATIVE
+    -b:        empty (plugin-specific handlers must determine this)
+
+    If 'wic -e' is not used, the user needs to select the appropriate
+    value for -b (as well as -r, -k, and -n).
+
+    The -o option can be used to place the image in a directory with a
+    different name and location.
+
+    The -c option is used to specify compressor utility to compress
+    an image. gzip, bzip2 and xz compressors are supported.

+
+NAME
+    wic plugins - Overview and API
+
+DESCRIPTION
+    plugins allow wic functionality to be extended and specialized by
+    users.  This section documents the plugin interface, which is
+    currently restricted to 'source' plugins.
+
+    'Source' plugins provide a mechanism to customize various aspects
+    of the image generation process in wic, mainly the contents of
+    partitions.
+
+    Source plugins provide a mechanism for mapping values specified in
+    .wks files using the --source keyword to a particular plugin
+    implementation that populates a corresponding partition.
+
+    A source plugin is created as a subclass of SourcePlugin (see
+    scripts/lib/wic/pluginbase.py) and the plugin file containing it
+    is added to scripts/lib/wic/plugins/source/ to make the plugin
+    implementation available to the wic implementation.
+
+    Source plugins can also be implemented and added by external
+    layers - any plugins found in a scripts/lib/wic/plugins/source/
+    directory in an external layer will also be made available.
+
+    When the wic implementation needs to invoke a partition-specific
+    implementation, it looks for the plugin that has the same name as
+    the --source param given to that partition.  For example, if the
+    partition is set up like this:
+
+      part /boot --source bootimg-pcbios   ...
+
+    then the methods defined as class members of the plugin having the
+    matching bootimg-pcbios .name class member would be used.
+
+    To be more concrete, here's the plugin definition that would match
+    a '--source bootimg-pcbios' usage, along with an example method
+    that would be called by the wic implementation when it needed to
+    invoke an implementation-specific partition-preparation function:
+
+    class BootimgPcbiosPlugin(SourcePlugin):
+        name = 'bootimg-pcbios'
+
+    @classmethod
+        def do_prepare_partition(self, part, ...)
+
+    If the subclass itself doesn't implement a function, a 'default'
+    version in a superclass will be located and used, which is why all
+    plugins must be derived from SourcePlugin.
+
+    The SourcePlugin class defines the following methods, which is the
+    current set of methods that can be implemented/overridden by
+    --source plugins.  Any methods not implemented by a SourcePlugin
+    subclass inherit the implementations present in the SourcePlugin
+    class (see the SourcePlugin source for details):
+
+      do_prepare_partition()
+          Called to do the actual content population for a
+          partition. In other words, it 'prepares' the final partition
+          image which will be incorporated into the disk image.
+
+      do_configure_partition()
+          Called before do_prepare_partition(), typically used to
+          create custom configuration files for a partition, for
+          example syslinux or grub config files.
+
+      do_install_disk()
+          Called after all partitions have been prepared and assembled
+          into a disk image.  This provides a hook to allow
+          finalization of a disk image, for example to write an MBR to
+          it.
+
+      do_stage_partition()
+          Special content-staging hook called before
+          do_prepare_partition(), normally empty.
+
+          Typically, a partition will just use the passed-in
+          parameters, for example the unmodified value of bootimg_dir.
+          In some cases however, things may need to be more tailored.
+          As an example, certain files may additionally need to be
+          take from bootimg_dir + /boot.  This hook allows those files

+NAME
+    wic overview - General overview of wic
+
+DESCRIPTION
+    The 'wic' command generates partitioned images from existing
+    OpenEmbedded build artifacts.  Image generation is driven by
+    partitioning commands contained in an 'Openembedded kickstart'
+    (.wks) file (see 'wic help kickstart') specified either directly
+    on the command-line or as one of a selection of canned .wks files
+    (see 'wic list images').  When applied to a given set of build
+    artifacts, the result is an image or set of images that can be
+    directly written onto media and used on a particular system.
+
+    The 'wic' command and the infrastructure it's based on is by
+    definition incomplete - its purpose is to allow the generation of
+    customized images, and as such was designed to be completely
+    extensible via a plugin interface (see 'wic help plugins').
+
+  Background and Motivation
+
+    wic is meant to be a completely independent standalone utility
+    that initially provides easier-to-use and more flexible
+    replacements for a couple bits of existing functionality in
+    oe-core: directdisk.bbclass and mkefidisk.sh.  The difference
+    between wic and those examples is that with wic the functionality
+    of those scripts is implemented by a general-purpose partitioning
+    'language' based on Redhat kickstart syntax).
+
+    The initial motivation and design considerations that lead to the
+    current tool are described exhaustively in Yocto Bug #3847
+    (https://bugzilla.yoctoproject.org/show_bug.cgi?id=3847).
+
+  Implementation and Examples
+
+    wic can be used in two different modes, depending on how much
+    control the user needs in specifying the Openembedded build
+    artifacts that will be used in creating the image: 'raw' and
+    'cooked'.
+
+    If used in 'raw' mode, artifacts are explicitly specified via
+    command-line arguments (see example below).
+
+    The more easily usable 'cooked' mode uses the current MACHINE
+    setting and a specified image name to automatically locate the
+    artifacts used to create the image.
+
+    OE kickstart files (.wks) can of course be specified directly on
+    the command-line, but the user can also choose from a set of
+    'canned' .wks files available via the 'wic list images' command
+    (example below).
+
+    In any case, the prerequisite for generating any image is to have
+    the build artifacts already available.  The below examples assume
+    the user has already build a 'core-image-minimal' for a specific
+    machine (future versions won't require this redundant step, but
+    for now that's typically how build artifacts get generated).
+
+    The other prerequisite is to source the build environment:
+
+      $ source oe-init-build-env
+
+    To start out with, we'll generate an image from one of the canned
+    .wks files.  The following generates a list of availailable
+    images:
+
+      $ wic list images
+        mkefidisk             Create an EFI disk image
+        directdisk            Create a 'pcbios' direct disk image
+
+    You can get more information about any of the available images by
+    typing 'wic list xxx help', where 'xxx' is one of the image names:
+
+      $ wic list mkefidisk help
+
+    Creates a partitioned EFI disk image that the user can directly dd
+    to boot media.
+
+    At any time, you can get help on the 'wic' command or any
+    subcommand (currently 'list' and 'create').  For instance, to get
+    the description of 'wic create' command and its parameters:
+
+      $ wic create
+
+       Usage:
+
+       Create a new OpenEmbedded image
+
+       usage: wic create <wks file or image name> [-o <DIRNAME> | ...]
+            [-i <JSON PROPERTY FILE> | --infile <JSON PROPERTY_FILE>]
+            [-e | --image-name] [-s, --skip-build-check] [-D, --debug]
+            [-r, --rootfs-dir] [-b, --bootimg-dir] [-k, --kernel-dir]
+            [-n, --native-sysroot] [-f, --build-rootfs]
+
+       This command creates an OpenEmbedded image based on the 'OE
+       kickstart commands' found in the <wks file>.
+
+       The -o option can be used to place the image in a directory
+       with a different name and location.
+
+       See 'wic help create' for more detailed instructions.
+       ...
+
+    As mentioned in the command, you can get even more detailed
+    information by adding 'help' to the above:
+
+      $ wic help create
+
+    So, the easiest way to create an image is to use the -e option
+    with a canned .wks file.  To use the -e option, you need to
+    specify the image used to generate the artifacts and you actually
+    need to have the MACHINE used to build them specified in your
+    local.conf (these requirements aren't necessary if you aren't
+    using the -e options.)  Below, we generate a directdisk image,
+    pointing the process at the core-image-minimal artifacts for the
+    current MACHINE:
+
+      $ wic create directdisk -e core-image-minimal
+
+      Checking basic build environment...
+      Done.
+
+      Creating image(s)...
+
+      Info: The new image(s) can be found here:
+      /var/tmp/wic/build/directdisk-201309252350-sda.direct
+
+      The following build artifacts were used to create the image(s):
+
+      ROOTFS_DIR:      ...
+      BOOTIMG_DIR:     ...
+      KERNEL_DIR:      ...
+      NATIVE_SYSROOT:  ...
+
+      The image(s) were created using OE kickstart file:
+        .../scripts/lib/wic/canned-wks/directdisk.wks
+
+    The output shows the name and location of the image created, and
+    so that you know exactly what was used to generate the image, each
+    of the artifacts and the kickstart file used.
+
+    Similarly, you can create a 'mkefidisk' image in the same way
+    (notice that this example uses a different machine - because it's
+    using the -e option, you need to change the MACHINE in your
+    local.conf):
+
+      $ wic create mkefidisk -e core-image-minimal
+      Checking basic build environment...
+      Done.
+
+      Creating image(s)...
+
+      Info: The new image(s) can be found here:
+         /var/tmp/wic/build/mkefidisk-201309260027-sda.direct
+
+      ...
+
+    Here's an example that doesn't take the easy way out and manually
+    specifies each build artifact, along with a non-canned .wks file,
+    and also uses the -o option to have wic create the output
+    somewhere other than the default /var/tmp/wic:
+
+      $ wic create ./test.wks -o ./out --rootfs-dir
+      tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/rootfs
+      --bootimg-dir tmp/sysroots/qemux86-64/usr/share
+      --kernel-dir tmp/deploy/images/qemux86-64
+      --native-sysroot tmp/sysroots/x86_64-linux
+
+     Creating image(s)...
+
+     Info: The new image(s) can be found here:
+           out/build/test-201507211313-sda.direct
+
+     The following build artifacts were used to create the image(s):
+       ROOTFS_DIR:                   tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/rootfs
+       BOOTIMG_DIR:                  tmp/sysroots/qemux86-64/usr/share
+       KERNEL_DIR:                   tmp/deploy/images/qemux86-64
+       NATIVE_SYSROOT:               tmp/sysroots/x86_64-linux
+
+     The image(s) were created using OE kickstart file:
+     ./test.wks
+
+     Here is a content of test.wks:
+
+     part /boot --source bootimg-pcbios --ondisk sda --label boot --active --align 1024
+     part / --source rootfs --ondisk sda --fstype=ext3 --label platform --align 1024
+
+     bootloader  --timeout=0  --append="rootwait rootfstype=ext3 video=vesafb vga=0x318 console=tty0"
+
+
+    Finally, here's an example of the actual partition language
+    commands used to generate the mkefidisk image i.e. these are the
+    contents of the mkefidisk.wks OE kickstart file:
+
+      # short-description: Create an EFI disk image
+      # long-description: Creates a partitioned EFI disk image that the user
+      # can directly dd to boot media.
+
+      part /boot --source bootimg-efi --ondisk sda --fstype=efi --active
+
+      part / --source rootfs --ondisk sda --fstype=ext3 --label platform
+

+
+      bootloader  --timeout=10  --append="rootwait console=ttyPCH0,115200"
+
+    You can get a complete listing and description of all the
+    kickstart commands available for use in .wks files from 'wic help

+    wic kickstart - wic kickstart reference
+
+DESCRIPTION
+    This section provides the definitive reference to the wic
+    kickstart language.  It also provides documentation on the list of
+    --source plugins available for use from the 'part' command (see
+    the 'Platform-specific Plugins' section below).
+
+    The current wic implementation supports only the basic kickstart
+    partitioning commands: partition (or part for short) and
+    bootloader.
+
+    The following is a listing of the commands, their syntax, and
+    meanings. The commands are based on the Fedora kickstart
+    documentation but with modifications to reflect wic capabilities.
+
+      http://fedoraproject.org/wiki/Anaconda/Kickstart#part_or_partition
+      http://fedoraproject.org/wiki/Anaconda/Kickstart#bootloader
+
+  Commands
+
+    * 'part' or 'partition'
+
+       This command creates a partition on the system and uses the
+       following syntax:
+
+         part <mountpoint>
+
+       The <mountpoint> is where the partition will be mounted and
+       must take of one of the following forms:
+
+         /<path>: For example: /, /usr, or /home
+
+         swap: The partition will be used as swap space.
+
+       The following are supported 'part' options:
+
+         --size: The minimum partition size. Specify an integer value
+                 such as 500. Multipliers k, M ang G can be used. If
+                 not specified, the size is in MB.
+                 You do not need this option if you use --source.
+
+         --source: This option is a wic-specific option that names the
+                   source of the data that will populate the
+                   partition.  The most common value for this option
+                   is 'rootfs', but can be any value which maps to a
+                   valid 'source plugin' (see 'wic help plugins').
+
+                   If '--source rootfs' is used, it tells the wic
+                   command to create a partition as large as needed
+                   and to fill it with the contents of the root
+                   filesystem pointed to by the '-r' wic command-line
+                   option (or the equivalent rootfs derived from the
+                   '-e' command-line option).  The filesystem type
+                   that will be used to create the partition is driven
+                   by the value of the --fstype option specified for
+                   the partition (see --fstype below).
+
+                   If --source <plugin-name>' is used, it tells the
+                   wic command to create a partition as large as
+                   needed and to fill with the contents of the
+                   partition that will be generated by the specified
+                   plugin name using the data pointed to by the '-r'
+                   wic command-line option (or the equivalent rootfs
+                   derived from the '-e' command-line option).
+                   Exactly what those contents and filesystem type end
+                   up being are dependent on the given plugin
+                   implementation.
+
+                   If --source option is not used, the wic command
+                   will create empty partition. --size parameter has
+                   to be used to specify size of empty partition.
+
+         --ondisk or --ondrive: Forces the partition to be created on
+                                a particular disk.
+
+         --fstype: Sets the file system type for the partition.  These
+           apply to partitions created using '--source rootfs' (see
+           --source above).  Valid values are:
+
+             ext2
+             ext3
+             ext4
+             btrfs
+             squashfs
+             swap
+
+         --fsoptions: Specifies a free-form string of options to be
+                      used when mounting the filesystem. This string
+                      will be copied into the /etc/fstab file of the
+                      installed system and should be enclosed in
+                      quotes.  If not specified, the default string is
+                      "defaults".
+
+         --label label: Specifies the label to give to the filesystem
+                        to be made on the partition. If the given
+                        label is already in use by another filesystem,
+                        a new label is created for the partition.
+
+         --active: Marks the partition as active.
+
+         --align (in KBytes): This option is specific to wic and says
+                              to start a partition on an x KBytes
+                              boundary.
+
+         --no-table: This option is specific to wic. Space will be
+                     reserved for the partition and it will be
+                     populated but it will not be added to the
+                     partition table. It may be useful for
+                     bootloaders.
+
+         --extra-space: This option is specific to wic. It adds extra
+                        space after the space filled by the content
+                        of the partition. The final size can go
+                        beyond the size specified by --size.
+                        By default, 10MB.
+
+         --overhead-factor: This option is specific to wic. The
+                            size of the partition is multiplied by
+                            this factor. It has to be greater than or
+                            equal to 1.
+                            The default value is 1.3.
+
+         --part-type: This option is specific to wic. It specifies partition
+                      type GUID for GPT partitions.
+                      List of partition type GUIDS can be found here:
+                      http://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs
+
+         --use-uuid: This option is specific to wic. It makes wic to generate
+                     random globally unique identifier (GUID) for the partition
+                     and use it in bootloader configuration to specify root partition.
+
+         --uuid: This option is specific to wic. It specifies partition UUID.
+                 It's useful if preconfigured partition UUID is added to kernel command line
+                 in bootloader configuration before running wic. In this case .wks file can
+                 be generated or modified to set preconfigured parition UUID using this option.
+
+    * bootloader
+
+      This command allows the user to specify various bootloader
+      options.  The following are supported 'bootloader' options:
+
+        --timeout: Specifies the number of seconds before the
+                   bootloader times out and boots the default option.
+
+        --append: Specifies kernel parameters. These will be added to
+                  bootloader command-line - for example, the syslinux
+                  APPEND or grub kernel command line.
+
+      Note that bootloader functionality and boot partitions are
+      implemented by the various --source plugins that implement
+      bootloader functionality; the bootloader command essentially
+      provides a means of modifying bootloader configuration.

+# This script runs tests defined in meta/lib/selftest/
+# It's purpose is to automate the testing of different bitbake tools.
+# To use it you just need to source your build environment setup script and

+# Call the script as: "oe-selftest" to run all the tests in in meta/lib/selftest/
+# Call the script as: "oe-selftest <module>.<Class>.<method>" to run just a single test
+# E.g: "oe-selftest bboutput.BitbakeLayers" will run just the BitbakeLayers class from meta/lib/selftest/bboutput.py

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

+			    PYBOOTCHARTGUI
+			   ----------------
+
+pybootchartgui is a tool (now included as part of bootchart2) for
+visualization and analysis of the GNU/Linux boot process. It renders
+the output of the boot-logger tool bootchart (see
+http://www.bootchart.org/) to either the screen or files of various
+formats. Bootchart collects information about the processes, their
+dependencies, and resource consumption during boot of a GNU/Linux
+system. The pybootchartgui tools visualizes the process tree and
+overall resource utilization.
+
+pybootchartgui is a port of the visualization part of bootchart from
+Java to Python and Cairo.
+
+Adapted from the bootchart-documentation:
+
+  The CPU and disk statistics are used to render stacked area and line
+  charts. The process information is used to create a Gantt chart
+  showing process dependency, states and CPU usage.
+
+  A typical boot sequence consists of several hundred processes. Since
+  it is difficult to visualize such amount of data in a comprehensible
+  way, tree pruning is utilized. Idle background processes and
+  short-lived processes are removed. Similar processes running in
+  parallel are also merged together.
+
+  Finally, the performance and dependency charts are rendered as a
+  single image to either the screen or in PNG, PDF or SVG format.
+

+Using OE images with QEMU
+=========================
+
+OE-Core can generate qemu bootable kernels and images with can be used 
+on a desktop system. The scripts currently support booting ARM, MIPS, PowerPC
+and x86 (32 and 64 bit) images. The scripts can be used within the OE build 
+system or externaly.
+
+The runqemu script is run as: 
+
+   runqemu <machine> <zimage> <filesystem>
+
+where:
+
+   <machine> is the machine/architecture to use (qemuarm/qemumips/qemuppc/qemux86/qemux86-64)
+   <zimage> is the path to a kernel (e.g. zimage-qemuarm.bin)
+   <filesystem> is the path to an ext2 image (e.g. filesystem-qemuarm.ext2) or an nfs directory
+   
+If <machine> isn't specified, the script will try to detect the machine name 
+from the name of the <zimage> file.
+
+If <filesystem> isn't specified, nfs booting will be assumed.
+
+When used within the build system, it will default to qemuarm, ext2 and the last kernel and 
+core-image-sato-sdk image built by the build system. If an sdk image isn't present it will look
+for sato and minimal images.
+
+Full usage instructions can be seen by running the command with no options specified.
+
+
+Notes
+=====
+
+ - The scripts run qemu using sudo. Change perms on /dev/net/tun to 
+   run as non root. The runqemu-gen-tapdevs script can also be used by
+   root to prepopulate the appropriate network devices.
+ - You can access the host computer at 192.168.7.1 within the image.
+ - Your qemu system will be accessible as 192.16.7.2.
+ - The script extracts the root filesystem specified under pseudo and sets up a userspace
+   NFS server to share the image over by default meaning the filesystem can be accessed by
+   both the host and guest systems.

+Welcome to sstate cache management utilities.
+sstate-cache-management.sh <OPTION>
+
+Options:
+  -h, --help
+        Display this help and exit.
+
+  --cache-dir=<sstate cache dir>
+        Specify sstate cache directory, will use the environment
+        variable SSTATE_CACHE_DIR if it is not specified.
+
+  --extra-archs=<arch1>,<arch2>...<archn>
+        Specify list of architectures which should be tested, this list
+        will be extended with native arch, allarch and empty arch. The
+        script won't be trying to generate list of available archs from
+        AVAILTUNES in tune files.
+
+  --extra-layer=<layer1>,<layer2>...<layern>
+        Specify the layer which will be used for searching the archs,
+        it will search the meta and meta-* layers in the top dir by
+        default, and will search meta, meta-*, <layer1>, <layer2>,
+        ...<layern> when specified. Use "," as the separator.
+
+        This is useless for --stamps-dir or when --extra-archs is used.
+
+  -d, --remove-duplicated
+        Remove the duplicated sstate cache files of one package, only
+        the newest one will be kept. The duplicated sstate cache files
+        of one package must have the same arch, which means sstate cache
+        files with multiple archs are not considered duplicate.
+
+        Conflicts with --stamps-dir.
+
+  --stamps-dir=<dir1>,<dir2>...<dirn>
+        Specify the build directory's stamps directories, the sstate
+        cache file which IS USED by these build diretories will be KEPT,
+        other sstate cache files in cache-dir will be removed. Use ","
+        as the separator. For example:
+        --stamps-dir=build1/tmp/stamps,build2/tmp/stamps
+
+        Conflicts with --remove-duplicated.
+
+  -L, --follow-symlink
+        Remove both the symbol link and the destination file, default: no.
+
+  -y, --yes
+        Automatic yes to prompts; assume "yes" as answer to all prompts
+        and run non-interactively.
+
+  -v, --verbose
+        Explain what is being done.
+
+  -D, --debug
+        Show debug info, repeat for more debug info.

+# DESCRIPTION
+# 'yocto-layer' is the Yocto Tool that helps users create a new Yocto
+# layer.  Invoking it without any arguments will display help screens
+# for the 'yocto-layer' command and list the available 'yocto-layer'
+# subcommands.  Invoking a subcommand without any arguments will
+# likewise display help screens for the specified subcommand.  Please
+# use that interface for detailed help.
