JEDI is "Joint Endeavor of Delphi Innovators", which is an long-time group of Delphi (and Pascal) developers who work together to create a nice, free library of routines and components for Delphi. SDL, or "Simple Directmedia Layer", is a low level, cross-platform media layer API which interacts with various multimedia devices, such as sound, video, 2D graphics and input. OpenGL is also supported to provide fast 3D rendering capabilities as well. It is designed to make development easier across multiple platforms using the same framework. JEDI-SDL is the Object Pascal translation of the original C headers. The goal is to offer all the functionality of the current version while maintaining compatability with various other platforms and Pascal compilers.
