Piki****Piki is a tiny wiki engine written in 1999 by MartinPool. The original version was less than 600 lines of Python code and is still available here: http://sourcefrog.net/projects/piki/ The version running on this site includes some enhancements by GerardoPoggiali and BernardoInnocenti, but still runs in less than 700 LOCs. You can grab the source code here: http://bender.codewiz.org/wiki/berniepiki.py
