Zwiki is a wiki engine written in Python and based on the Zope web application server, that was under development from 1999 to 2009. It was developed by Joyful Systems and contributors from around the world, and is free software released under the GNU General Public License.
Zwiki supports a number of wiki markup styles out of the box, including MoinMoin, Structured text, reStructuredText, but allows also to edit pages in LaTeX or wysiwyg HTML. Zwiki can also co-exist with the Plone content management system. The Zope 2 and Zope 3 projects use Zwiki for part of their documentation.
Zwiki also offers email-integrated discussion, an integrated issue tracker, internationalization support, precise access control (using the Zope Application Server's ACL functionality), and many more optional features such as fuzzy urls, automatic page hierarchy, use of external editors, embedded DTML scripts, and RSS feeds for changed and newly created pages.
