 # This script is intended to support the GitHub workflow described here:
 # https://trac.webkit.org/wiki/UsingGitHub
 #
 # This script fetches the latest changes from upstream, and pushes those
 # changes to the master branch in origin (e.g., your GitHub fork of WebKit).
 #
 # Running this script periodically will keep your fork of WebKit on GitHub in
 # sync with the "root" WebKit repository in upstream, assuming you've run
 # configure-github-as-upstream
