That's why somelike Mathematica-machine is needed :).

I think one can define binding-functions (in lisp environment) (such as SET)
and then just call the EVAL function.

I have some Mathematica modules (.m files) which I would like to run without
use of Mathematica (they use a little number of functions (and some of them
were actually transtaled from fortran automatically)).

Feyncalc is not simple package. I'm not sure that those binding-functions
which cover all my needs will be enough to run Feyncalc under MAXIMA.
