Oh... where is the fricas script then? AFAIK FRICASsys relies on the
environment variable FRICAS to be set. No idea how this is on Windows,
though. Shouldn't fricas be started by the script and that script must
set the FRICAS variable? Perhaps you must ask the user to adapt the path
in the script, if s/he doesn't install into the default system localtion.

As a fallback I think that would be acceptable. I'm not sure whether
that should come together with a warning about a missing value for the
FRICAS variable or whether such a warning is just useless noise.
