Usage: . $SCRIPT [options] [feature [feature [... ]]]

Version: $VERSION
Compatibility: bash, zsh, ksh

Options:
   -m|--machine <machine>
      what machine to use
      default: '$DEFAULT_MACHINE'
   -b|--build <directory>
      build directory to use
      default: '$DEFAULT_BUILDDIR'
   -s|--script <filename>
      file where setup script is generated
      default: none (no script)
   -f|--force
      flag to force overwriting any existing configuration
      default: false
   -r|--rpm-revision <schema>
      Specify how to handle RPM packages revisions
      <schema> can be:
          'prservice[:<address>]' : Use a PR service daemon.
              if <address> is not specified, the default value 'localhost:0'
              is used (shortcut for a PR service started by bitbake)
          'timestamp' : Use a generated time stamp (UTC).
          'value:<revision>' : Use <revision> explicitly.
          'none' : Do nothing.
   -t|--topic <value>
      Specify an optional topic for this setup.
      If specified, the topic will be propagated in build manifests:
         - in deployment dir: tmp/deploy/images/*/build-info
         - in target image: /etc/platform-info/build
         - in SDK: tmp/deploy/sdk/*.build-info
   -v|--verbose
      verbose mode
      default: false
   -V|--version
      display version, set AGLSETUP_VERSION variable with version value and exit
   -d|--debug
      debug mode
      for early debug, set env variable DEBUG. 
      for example:
           DEBUG=true source aglsetup.sh -V
      default: false
   -h|--help
