MORE INFO
=========
The Sauerbraten sources are very small, compact, and non-redundant, so anyone wishing to modify the source code should be able to gain an overview of Sauerbraten's inner workings by simply reading through the source code in its entirety. Small amounts of comments should guide you through the more tricky sections.

When reading the source code and trying to understand Sauerbaten's internal design, keep in mind the goal of Cube: minimalism. I wanted to create a very complete game / game engine with absolutely minimal means, and made a sport out of it keeping the implementation small and simple. Sauerbraten is not a commercial product, it is merely the author's idea of a fun little programming project.
