[Gambas-user] Translate a Project

[Nx GT-R BOY]

I, have a question about a Project translation.

I have read of course the howto guide:
http://www.gambasdoc.org/help/howto/translate

But, what's next? I have my *.po in my .lang directory, so, how do I change
my project language, I read something about environment variables (another
site) must be set in a console but not sure, because the "howto" don't say
nothing about this variables.

Freespire 2.0
Gambas 2.0

Thanks,
