Has anybody made a german version of the GhostDoc template textes?
As far as I am aware, GhostDoc bases its processing on a hard-coded set of parsing rules based on programmer-English conventions. I've written an alternative add-in (AtomineerUtils) which uses an Xml-based rules file that is language independent, so it would be very easy to convert the rules for use in a different language.
