I finally after too much of pondering started my project on googlecode. One of the best features I liked about googlecode was the revision control for wiki, where I can add/edit
After lot of googling, I think the only way is
download the wiki-repository, and edit pages manually through Vim or any text editor following the wikiSyntax. Then do an
hg commit / hg add -- based on if u edited or added a file.
and then,
hg push
to upload your files to the main wiki
Well, if you have saved the whole wiki, can't you open that up in your browser and just edit it like any other Wiki?
