its diverse submenus, and you'll see how important the plug-in

by the aid of so called ``Scheme-Scripts'', small programs written
in a strange-looking language called ``Scheme'', which is strongly
connected with Lisp--some of you have certainly heard this name in
connection with artificial-intelligence programs."
"Lisp and Scheme are powerful, flexible and elegant languages,
but they are certainly not easy to learn..."
"To make writing scripts easier, Marc Lehmann set out... to
make it possible to write GIMP scripts using... Perl... the
language is much easier to learn than Script-Fu... Too, and this is
the main advantage in my opinion, most cgi-scripts and web-based
programs are written in Perl, so many people already know the
