Jot

Jot is yet another wiki engine. It is a project of Scott Moonen. If you are interested in Jot for the sake of using it, contact Scott.

The two primary distinctives of Jot are that it is written in Python and it uses a persistent object store for its page database. Both of these allow for code that is more simple and elegant than most wiki engines.

It's possible you're looking for JotSpot instead. This wiki engine bears no relation to JotSpot, though it's flattering to see that someone else thought to associate "jot" with wiki.
