    This script will release the repo by creating a custom Git tag. Travis will run the appropriate scripts to
    automatically bump version numbers, build, shrinkwrap, test, install, and publish the release.

    When the release is complete, the custom Git tag is removed from GitHub. The custom tag is created using a clone so
    it won't persist in your local repo.

    If the release is successful, RCUE, Angular PatternFly, and PatternFly Org will be released as well. This is done
    by creating a Git tag for the next repo to be built.

    If 3.15.0 is provided as a version number; for example, the release will be tagged as v3.15.0.

    Release notes must be added via GitHub.

    Note: Builds can only be stopped via the Travis UI: https://travis-ci.org/patternfly

    sh [-x] $SCRIPT [-h|f|n|s] -a|e|o|p|r|w|x -v <version>

    Example: sh $SCRIPT -v 3.15.0 -e

    OPTIONS:
    h       Display this message (default)
    a       Angular PatternFly (DISABLED for semantic release)
    e       PatternFly Eng Release (DISABLED for semantic release)
    o       PatternFly Org
    p       PatternFly (DISABLED for semantic release)
    r       RCUE
    v       The version number (e.g., 3.15.0)
    w       PatternFly Web Components (DISABLED for semantic release)
    x       Patternfly NG (DISABLED for semantic release)

    SPECIAL OPTIONS:
    s       Skip chained releases.
    f       Run against repo fork matching local username (e.g., `whoami`/patternfly)
    n       Release PF 'next' branches (e.g., PF4 alpha, beta, etc.)
