Translations

I just received an offer to translate the Pocketcity into Catalan; which I appreciate. He’s mentioned that he’d like to have the .po files which tells me that I’m probably doing the translation of the application all wrong.
Currently I’m using the lang attribute of the .rcp files to split up all the separate languages that are used, and I realize that I could miss strings using this method. I have found that during testing I have missed strings so the ould is a bit of a misnomer.
