Python – Is there free wiki source code that will run on the Google App Engine?

I found the sample code cccwiki which is good, but I would like a wiki that keeps tracks of all revisions to the pages and lets users show diffs and revert to previous versions.

Best Solution

You can start with http://code.google.com/p/google-app-engine-samples/downloads/detail?name=cccwiki_20080409.tar.gz&can=2&q= which is exactly "A simple Google App Engine wiki application" for you to download, try, and modify as you want. You can also browse its sources online at http://code.google.com/p/google-app-engine-samples/source/browse/trunk/cccwiki/ .
