Thanks, Leo, I have used grep for over 30 years, and in fact finally did
resort to looking through the share directories, which no user should have
to do. Your regexp works, but of course if the name had been changed to
%solve (as apparently it will be!) or whatever, or if the package had been
rewritten in Lisp, or if the arguments were on a separate line, etc. it
would not.

                -s
