The entirety of the content here is based on 'vst.h', 'VST 3 SDK' and 'VSTGUI'. Due to the license header provided in the files investigated, the final license for these files is the BSD 3-Clause license. It was about a day and a half of work, but it is almost in working condition.
While not all features/functionality is present, the main functionality that makes vst2wrapper compile is there. So with any luck I'll be able to figure out the rest with ease.
