rsiska has Groovy scripts that are much better than those I've done in the scope of my Jenkins PoC that reported on obsolete / to be translated keys.

Somebody should upgrade those scripts to:

1. Magnolia 6.2
2. be run automatically

Then I could have Jenkins run them weekly, so that cleaning up obsolete keys can be resumed, and keys to translate given to interested people. (Sales have volunteered to translate to German and Italian.)
