Wiki engine evolution tree

This is just a subjective approach to a classification of wiki engines according to their origins (where the original programmer of the wiki engine got the idea of deriving a new wiki engine).

In other words: This is supposed to be a tree of the evolution of wiki engines (not wiki forums, but wiki engines). It is supposed to show where a wiki engine was derived from. Of course, this can be very subjective.

(wiki engine, year the development of the wiki engine started, first programmer, original programming language of the wiki engine, project or community the engine was originally made for, basic features that are new)
