I’ve decided to move the git repositories for MKVToolNix and for mo-git-blame to GitHub, the social coding site. You can find MKVToolNix at https://github.com/mbunkus/mkvtoolnix and mo-git-blame at https://github.com/mbunkus/mo-git-blame.
You can update existing repositories by editing the file .git/config and replacing all entries “url = git://git.bunkus.org/mkvtoolnix.git” with “url = git://github.com/mbunkus/mkvtoolnix.git” and running “git remote update” afterwards.
I haven’t decided yet whether or not to use GitHub’s issue tracking system instead of my own Bugzilla installation. So for the time being you can still use it.
