Something that is very much in the back of my mind whilst developing mosquitto is that it should have support for language translations. I've been reluctant to start this effort until development was a little bit more settled, to avoid wasting translators time. I think it's now time to start the ball rolling.
I'm going to approach this in two stages - the man pages and the programs. Man pages are first. I've imported the translation templates to launchpad, so if your native tongue is anything other than English and you'd like to translate them - please go ahead. I'll be putting any translated man pages (with credits :) into the upcoming 0.9 release. I think I've finished making changes but if I haven't, the one most likely to change is for mosquitto.conf
The translation page can be found at http://translations.launchpad.net/mosquitto/trunk
Thanks in advance, and please get in touch if you find any strings that don't make sense.
