This is improved and fixed syntax file originally taken from here. I know, it's over-engineered, but I like it this way. Embedded in comments is my color "extravaganza" and, yes, I'm still stuck in "the more colors, the merrier" phase.

Keywords are split into three groups. Would have been more ;) but JED went on strike and borked with error message and I didn't press the issue. If you know of a fix and deem it communicative my e-mail is in the foot of the page, tho doubly obfuscated (death to the spammers!), hope you connect the clues ;). In first two groups I followed example of vim. While third contains mathematical and predicate? keywords.

I think it manages quite well. It's still work in progress as I'm new to Scheme and making syntax files for JED. Because it departs from original version I decided to place it here but with time it may be worthy of inclusion into the official JED distribution. Last but not least, quick helpful installation notes are provided in heading comments. Standard disclaimers and bug report, hate-mail enticements follow ...
