+
+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 'mic' 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 -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.
+
+    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:        HDDDIR and STAGING_DATA_DIR (handlers decide which to use)
+
+    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.
+
+    As an alternative to the wks file, the image-specific properties
+    that define the values that will be used to generate a particular
+    image 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 image creation.
+
+    The set of properties available for a given image type can be
+    listed using the 'wic list' command.

+DESCRIPTION
+    This command enumerates the complete set of possible values for a
+    specified option or property needed by the image creation process.
+
+    This command enumerates the set of available canned images as well
+    as help for those images.  It also can be used to enumerate the
+    complete set of possible values for a specified option or property
+    needed by the image creation process.
+
+    The first form enumerates all the available 'canned' images.
+    These are actually just the set of .wks files that have been moved
+    into the /scripts/lib/image/canned-wks directory).
+
+    The second form lists the detailed help information for a specific
+    'canned' image.
+
+    The third form enumerates all the possible values that exist and
+    can be specified in a OE kickstart (wks) file.  The output of this
+    can be used by the third form to print the description and
+    possible values of a specific property.
+
+    The fourth form enumerates all the possible options that exist for
+    the set of properties specified in a given OE kickstart (wks)
+    file.  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 image.  Some example output for the 'list <wks file>' command:
+
+    $ wic list test.ks
+    "part" : {
+        "mountpoint" : "/"
+        "fstype" : "ext3"
+    }
+    "part" : {
+        "mountpoint" : "/home"
+        "fstype" : "ext3"
+        "offset" : "10000"
+    }
+    "bootloader" : {
+        "type" : "efi"
+    }
+    .
+    .
+    .
+
+    Each entry in the output consists of the name of the input element
+    e.g. "part", followed by the properties defined for that
+    element enclosed in braces.  This information should provide
+    sufficient information to create a complete user interface with.
+
+    The final form enumerates all the possible values that exist and
+    can be specified for any given OE kickstart (wks) property.  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.
+
+    $ wic list property part
