OK, sounds reasonable enough. However, I am *completely* translations illiterate. :-) How would I go about generating this compendium, and would I just make it available on the servers or should it go into GIT?
I am probably as illiterate as you when it comes to translation. Anyhow here: http://websvn.kde.org/trunk/l10n-kde4/templates/messages/kdelibs/kdelibs4.po... you can see an example of what a .pot file looks like (it is for kde4, but you can open it in Kbabel even if it complains about the header format). My guess is that it is a concatenation of the different po files available. The attached screenshot shows an example, the red rectangle shows a translated string.
The main thing though is that .po files are not fully updated to the current sources, so we need one or more volunteers to do the update job :) This does not require programming skills, so even simple users can contribute to it.
