I agree. I suggest a variable FRICASCMD, which holds the path to fricas. This
is more flexible than FRICASROOT. Maybe we should also change the name from
AXIOMEDITOR to FRICASEDITOR globally, although this will break the installation
of many people...
Could you replace '???' by the apropriate magic in Makefile.in below, test and
commit?
Thanks,
Martin
BTW: ideally, maybe you could also test other shells. I vaguely recall having
problems with a tcsh.
