In order to compile and run frocor, you need:

* A GNU/Linux system with most "normal" basic packages (gcc, libc, X11 etc.)
  --> Other Unixes may also work but have not been tested
* The free pascal compiler (fpc) to compile ocor and ocor-sdlclient
* libsdl for ocor-sdlclient
* optionally libsdl and libsdl_GFX for fms (can be disabled with make subX in
  fms directory)
* qt3 by trolltech for frocor-player

Don't forget you also need the -dev packages, if they exist.
