My students have been using that very T-Gen port for the last two 
semesters: to build HTML parsers in the Spring, and to build LaTeX 
parsers in the Summer.  We have found a few bugs (e.g., you can't 
actually build some of the more advanced kinds of parse trees, 
because the methods for creating and installing your own subclass of 
the parse tree are missing), but lots of students have used it 
successfully.
