These Eclipse-Features add dictionaries for the German language (Deutsch). If you are using Eclipse for Java development you have to use the version for JDT, but if you are developing in C++, you have to use the CDT version. In case you install the wrong version the full other development environment will be installed.
Based on the dictionary from Free German Dictionary from Jan Schreiber.
