Starting with todays tarball, there is a manpages.pot in docs/man/ folder of the tarball. I created this with po4a to make it possible for you to translate the manpages in the same quality you do it for the app already.
Just copy this file to manpages-XX.po where XX is you language-code (things like es_mx are supported aswell), and use your favorite app to work with. I'll set up a wiki-page where you can read more details about this.
In tomorrows tarball will be the script translate-manpages in src/utils/scripts/. With this script you can create the translated manpages to see if everything worked fine. If you can't or don't want to install po4a: No problem, just post the .po here or send it directly to me, I'll do the rest for you.
