d20 Class Construction Engine

From the introduction: [An] attempt to create a point-based system that GMs can use to build fantasy Classes within the framework of the Core Rulebooks. Of course, the existing Classes have more balance to them than previous editions of the game, but are somewhat difficult to accurately reconstruct with these rules, due to their inherent imbalances. ... This engine was created with as little regard to actual GM play-style and setting dependences as possible.
