Gimp currently uses SIOD, which is a nonstandard implementation of Scheme with some of the standard Scheme functions, some functions imported from C, and some just plain strange stuff (what is the MD5 calculator doing in a "lightweight" scheme implementation?). A hodgepodge of stuff, really. Then, of course, there is the gimp extensions to it, which are rather strange in of themselves... Anyway, the definative reference for SIOD is now http://people.delphiforums.com/gjc/siod.html (it took some poking around to find that site -- most people refer to an older document at indiana.edu) Rockwalrus
