Now edit all files that have been replaced above (i.e. using kbabel
or gtranslator) and mail the changes to gosa@oss.gonicus.de to be 
included in the next release.

To see the changes you've made in GOsa, run "msgfmt messages.po" on
your freshly edited files and restart your apache after that. Set
the webbrowser to the language you've edited and go back to the
login screen.
