I jest tried a efricas and I have found a bug in efricas and fricas
mode. Namely, fricas mode seem to use just 'fricas' as program name
assuming that fricas is in the path and that the version in the path
is the correct one. This is reasonable given no extra assumptions.
However, one can install fricas in any strange directory and it
should run OK regardless of the path. In such situation efricas
fails -- emacs can not run fricas, or worse, runs wrong version
of fricas. But efricas can know exact location of fricas, so it
can and should use full pathname.
So I think that:
- fricas mode should take fricas location from a variable, if
this variable is unset default to plain 'fricas'
- efricas should set this variable to full pathname of fricas.
