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 {domain}.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.
