 xCAT/PCM Kit Build utilities

    usage: buildkit [-h|-v] [command [-V]]

    This tool is used to create and build a new Kit.

    The options are:
        -h                - Provide usage info.
        -v                - Provide the version info.
        command           - Several commands are supported. See the list below.
        -V                - Verbose mode. Outputs additional debug messages.

    Supported commands:
     create <kit basename> - creates a new Kit with the specified basename
     chkconfig             - checks the Kit build file
     buildrepo <reponame>  - builds the specified Kit package repository 
     buildrepo all         - builds all the Kit package repositories
     listrepo              - lists the Kit package repositories in the Kit
                             build file, and their build status
     cleanrepo <reponame>  - deletes the build files for the specified Kit
                             package repository
     cleanrepo all         - deletes the build files for all Kit package 
                             repositories
     buildtar              - builds the Kit tarfile
     cleantar              - deletes the Kit deployment directory and Kit
     cleanall               - equivalent to buildkit cleanrepo all and
                                            buildkit cleantar
     addpkgs -p <packagedir> [-k|--kitversion <version>] [-r|--kitrelease <release>] <kit tarfile>
                           - used by customer to add external product
                             packages when they are not built into the 
                             shipped kit tar file

This script is designed to run on a non-xCAT system so that Kits can be
built on any product build machine.

=head3   update_kitcomp_kitpkgdeps 
	
      Update the kitcomponent kitpkgdeps string
        For any kitpkgdep that does not explicitly specify a version-release
        comparison string and for which an rpm exists in the repo,
        query the rpm for its version-release info and set an explicit
        comparison string.
      Reason we need to do all this:  We need to force yum/zypper to update
        the product rpms.  A simple package name in the kitcomponent meta rpm
        REQUIRES entry will not cause the product to get updated if an older 
        version is already installed.  Need to explicitly require this version
        and release of the product package.
