To comply with the LGPL requirements, the sources of used LGPL libraries are
available for download. SDL_gfx and Plib are statically linked to the glGo Linux
binary, so in order to relink with a modified SDL_gfx or Plib you need to
download the glGo object files and run the provided Makefile. The other SDL
libraries are dynamically linked, so you can just replace the shared libraries
without the requirement to relink glGo. On Windows all LGPL libraries are
dynamically linked, so the Windows object files are not required.

All libraries used by glGo are the unmodified, original versions as distributed
on each libraries homepage.
