More than just plugins, this package is a customized JSPWiki that replaces the standard text files for page storage with a simple and fast java object database.

This version runs about 20 times faster than the original, making it suitable for very large wikis with a great number of pages.
This jar file is just a dump of all the JSPWiki source after modification along with all the additional TwinFeats source code needed. Better packaging will hopefully come as I have more time, but for the curious I've made the source available now:
