welcome to the club!

you'd be surprised! :-)

what is your platform?
did you build today to pre-test the release?

CLISP is under GPL, ImageMagic under a BSD-style license (IIUC).
at any rate, there should not be a problem to interface CLISP with
ImageMagic.

I thought about it - and decided that this is a great idea.
I did not have time then, unfortunately.
I have even less time now. :-(

I suggest that you make it a CLISP module and contribute it to CLISP.
have a look at modules/regexp/

I don't think this is useful.  reimplementing everything one more time
in yet another language is for learning that other language, not for
the "real life".

good luck!
