        Use this tool to find HTML classes that we use in our JS code.
        This looks for calls to addClass, and if you use the -v option,
        you will get a display of (fn, html_class) tuples that
        represent addClass calls.

        If you call it with no options, the tool acts as a linter, and
        it will complain if it can't resolve the class for an addClass()
        call.
