Tu Parle Bazaar?
Bug 83941 Bzr doesn't speak my tongue has been closed. Bzr can now be translated. If you want to help bring bzr to those who prefer to work in non-English languages please help translate at Launchpad (you will need to be in the appropriate Launchpad translations team).
The translation will involve quite a bit of specialist language (what is French for "colocated branch"?) and I expect there are strings yet that need to be added to the translation file. I also need to look at translations for plugins.
