A big thanks to Dave Chapeskie (dchapes@ddm.wox.org) for lots of great
suggestions for improving IFM, and also for setting up a web page of IFM
maps (www.sentex.net/~dchapes/ifm).

Thanks to Dan Eble (eble@ticalc.org) for patches to improve PostScript
output, and a bug fix.

Thanks also to Denis Auroux for writing gpp, the Generic Preprocessor.
Very useful!
