        This program will search through a XeLaTeX file for a magic string:
            \begin{glossary}
        Once it finds it, it will then process everything until it finds a
            \end{glossary}
        In between these items, it is expecting pairs of lines:
        one in English and one in ASL.

        While we are doing that we should account for TeX commands so that
        we don't inadvertently think that one of the vocabulary words
        is '\columnbreak', but I don't. Instead I add in keywords that
        have troubled me.
