Comment 9 for bug 376464

The source code of our tool is public, and the developper (Istvan) is active and responsive, so it should be easy to make a copy/mirror on Ubuntu.com

As for the link, you obviously need to be logged into Launchpad to contribute (otherwise Launchpad tells you to do so) but it will let you propose a suggestion for your language (and even other languages).

The url is able to be modified according to the system locale using the various parameters (such as language=fr, release=raring & packagename=gnome-screenshot,repo=universe,isok=false)

The URL I gave was misleading because I used placeholders. Here's one that's working. I just changed language from fr to es, and i set packagename to kaffeine.

This one will look for Kaffeine in French:
http://nightmonkey.ubuntu.hu/#release=raring&language=fr&view=pack&repo=universe&isok=false&rownumber=100&sortpopcon=dsc&packagename=kaffeine&page=null

This one for Kaffeine in Spanish
