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://sourceforge.net/projects/piki/]]

The version running on this site includes some enhancements
by GerardoPoggiali and BernardoInnocenti, but still runs in
less than 700 LOCs.
