/* Version 0.2 22/07/97 written by IceBreak (ice_break@hotmail.com) */
/* 0.2: Finnally I rewrote the playing method inside the cdrom player to work
* with msf instead of lba, and frames instead of tracks, this should fix
* all the compability problems that the cdroms player had with some
* cdroms. I also fixed some bugs and better problem messages.
* FreeBSD support added by Eric A. Griff aka setjmp!eagriff@*.global2000.net
