The top-level directory structure is as follows:

3rd_Party_Tools_Data -> tools unrelated to the WordNet.Net library, but having some use in processing words.

Contributed Extras -> tools directly useful for working with the WordNet.Net library contributed by individuals not associated with the WordNet.Net project.

Library -> This is the WordNet.Net API source.

Projects -> These are more major projects which utilise the WordNet.Net library either contributed externally or internally.

Samples -> Sample implementations of the WordNet.Net library.

Tools -> Tools related more to analysing the WordNet database using the API, contributed extras code, and whatever other resources might be available.
