Translation tools (statistics etc.)

I’m looking for any tools / scripts to ease translating FreePBX.
Especially, I’d like to produce transltion statistics for all / one language, either as they do e.g. for FileZilla or poedit - or as the FreePBX spanish translation has (wtf is the “translations_report.pl”?)

…found translations_report.pl, it’s in I18n/Spanish/FreePBX.tar.gz
for german (de_DE) version, see http://www.freepbx.org/trac/wiki/I18n/German
