%description
    GIT is a "directory content manager" designed to handle absolutely
    massive projects with speed and efficiency. GIT falls in the
    category of distributed source code management tools. Every GIT
    working directory is a full-fledged repository with full revision
    tracking capabilities, not dependent on network access to a central
    server.

%track
    prog git = {
        version   = %{version}
        url       = http://git-scm.com/downloads
        regex     = version.>\s*(\d+(\.\d+)+)
    }
