The OpenThesaurus German Dictionary Plugin (formerly Thesaurus Deutsch) extends Apple's Dictionary application (Dictionary.app) with a German thesaurus.
You can search for every synonym not just the primary word.
You can search for parts of a hyphen delimited term or a word which is not located at the beginning of a term (as Dictionary normally does).
This is a offline dictionary, so you don't need an internet connection.
The dictionary content is based on the online dictionary www.openthesaurus.de by Daniel Naber.
Updated the dictionary content to the OpenThesaurus database from 2008-05-14.
The footer can now be hidden.
The download is now an internet-enabled disk image instead of a zip archive.
Version 08.04.09

Now under GPL v3.
