Well, this won't be a long page -- I work alone, and I try to use as much original code as posible. But I'm not crazy either. :)
I am indebted to Slava Pestov and his associates for releasing his code for a syntax coloring engine into the public domain -- Arachnophilia's syntax-coloring engine is largely based on this earlier work. For more detail, please read Mr. Pestov's README file.
I mean this acknowledgment sincerely. My efforts at syntax coloring engines to date have been rather pokey and limited. Mr. Pestov's core syntax coloring engine code has greatly improved Arachnophilia.
