Usage: $0 [options] [-- joboptions]
  Use this script to remotely trigger a Mistify build on a Jenkins CI server.
  The Jenkins CI server must be configured to run the buildmistify script on the
  server in order to build.
  Options:
    ==== remote build ====
    --jenkins <url>
        The Jenkins CI server URL. The URL is saved in the file
        $statedir/jenkins.
        [jenkins=$jenkinsdefault]
    --job <job>
        The job to execute. This must match a name in the Jenkins job list. This
        is saved in the file: $statedir/jenkinsjob
        [job=$jenkinsjobdefault]
    --mistifybranch <branch>
        The Mistify-OS branch or tag to checkout for the build.
        This is saved in the file: $statedir/jenkinsmistifybranch
        [mistifybranch=$jenkinsmistifybranchdefault]
    -- <joboptions>
        Anything following the "--" is passed directly to the Jenkins server.
        This can be additional options to pass to a script or a complete
        command line depending upon how the job is configured on the server. The
        job needs to be configured to accept a parameter named "mistify_job_options".

    Parameters passed to the Jenkins server:
        [mistify_branch=$mistifybranch]
        [mistify_job_options=<joboptions>]
    ==== other ====
    --resetdefaults
        Reset options back to their default values.
    --dryrun
        Just testing what will happen with this script. Don't send anything to
        the Jenkins server and instead display the command.
    -h|--help
        Display this usage.

  NOTE: This script maintains state in $statedir.
