That I noticed, of course. :)

Hmm... And this is unknown. At least some gamalg files (as I mentioned
-- compiled to lisp code), as well as gam.usg, is still distributed with
Maxima. So probably it is a good idea to delete it from the
distribution, for not to mislead people.

I would be glad to find it :):):):)

I know, and I am using FeynCalc in fact, though there are some issues
that makes it a bit inconvenient (specifically the fact that Mathematica
is not free). But writing the whole package from scratch is something
that I am a bit lazy to do.
