Wix is a cvs-like command line interface for Mediawiki driven wiki websites. It allows you to work offline with the editor of your choice, and to check for conflicting changes, and commit your local version of the wiki pages in separate steps.
As of this writing Wix is now available as the CPAN module WWW::Mediawiki::Client, and is now in its second revision there. You can download it from there and install manually, or use any method you would normally use to install CPAN modules.
Wix currently uses a CVS inspired interface. While this works pretty well, it's possible that there are other interface ideas which would be superior. Let's investigate these ideas, perhaps in the forum of this page's talk page. A few of the TODO items concern just such changes.
Patches and suggestions are very welcome. Here's a TODO list of things I have in mind to do to improve Wix from here (I'd love to see other ideas):
