LibSGD stands for Lib Simple Game Development and is an easy to use library for BlitzBasic, BlitzMax, Node.js, C/C++ and Python.
It's still under development and maintained by Mark Sibly. This page is just an entry point for now as the information about it is a bit cluttered across several pages at the moment.
