    This script will bump version numbers that semantic release does not handle

    For PatternFly, the version number in $PTNFLY_SETTINGS_JS is bumped. For PatternFly and Angular PatternFly, the
    version number in $BOWER_JSON is bumped.

    sh [-x] $SCRIPT [-h] -a|p| -v <version>

    Example: sh $SCRIPT -p -v 3.15.0

    OPTIONS:
    h       Display this message (default)
    a       Angular PatternFly
    p       PatternFly
    v       The version number (e.g., 3.15.0)

    SPECIAL OPTIONS:
    s       Skip publishing branch (for use with latest semantic release prepare plugins)
