From: Benoit Person <benoit.person@xxxxxxxxxx> For now, Git::Mediawiki contains nothing. This first patch moves some of git-remote-mediawiki.perl's factorisable code into Git::Mediawiki. In the same time, it removes the side effects of that code and renames the fucntions and constants moved to expose a better API.
