These tmbundles are intended to cover the languages as roughly defined by Ada 95, Fortran 77, Fortran 95, and GNU Pascal.
I'm not an expert at any of these languages, but I believe the folding for Ada and Pascal is useful.
As for Fortran folding, I didn't even try. I'm happy to add folding support if someone will tell me where best to start and end the folds. (Or, of course, you're welcome to modify the tmbundle and upload it yourself :).
