BGMP 1.7.1 will be internationalized and ready for localization, but I could use some help making localizations, since I'm only fluent in English.
If you'd like to make a localization for your language, you can learn how by reading Translating WordPress and How to Create a .po Language Translation.
You'll need the .pot file. Once you're done, just contact me and send me the .po and .mo files, and I'll add them to the next release.
I did create a machine-translated localization for French, but it could definitely use improvement from a human being.
