... but be careful. Sending arbitrary strings from the internet to
maxima is a bad idea unless the maxima process has no privileges to
break anything: Using the ":lisp (foo)" convention, together with
whatever command your lisp implementation uses to call other programs,
would let the user run arbitrary code with the privileges of the maxima
process.
