"""Manage releases of JPython.

Usage: %(program)s [options] tagname

Where `options' are:

    --tag
    -t
        Tag all release files with tagname.

    --TAG
    -T
        Like --tag, but relocates any existing tag.  See `cvs tag -F'.  Only
        one of --tag or --TAG can be given on the command line.

    --prep
    -p
        Prep the release for running the Jshield installer

    --build
    -B
        Do the build by running the Jshield installer

    --bump
    -b
        Bump the revision number to tagname

    --clean
    -c
        Clean up after ourselves

    --help
    -h
        Print this help message.

    tagname is used in the various commands above.  It should essentially be
    the version number for the release, and is required.  E.g. `1.1beta4'
