    # (and are obviously the most common..oh, the competition.)

    #       problem (e.g. you want to have a page named "commit"
    #       for whatever silly reason), consider transforming
    #       the filenames to use WikiCase for URIs. I.e.,
    #
    #           /commit => some commit resource

    #           /Commit => commit.txt     # Or whatever
