- * As of Linux 2.1.x, all Linux CD-ROM application programs will use this
- * (and only this) include file. It is my hope to provide Linux with
- * a uniform interface between software accessing CD-ROMs and the various
- * device drivers that actually talk to the drives. There may still be
- * 23 different kinds of strange CD-ROM drives, but at least there will
- * now be one, and only one, Linux CD-ROM interface.
- *
- * Additionally, as of Linux 2.1.x, all Linux application programs
- * should use the O_NONBLOCK option when opening a CD-ROM device
- * for subsequent ioctl commands. This allows for neat system errors
- * like "No medium found" or "Wrong medium type" upon attempting to
- * mount or play an empty slot, mount an audio disc, or play a data disc.
- * Generally, changing an application program to support O_NONBLOCK
- * is as easy as the following:
- * - drive = open("/dev/cdrom", O_RDONLY);
- * + drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
- * It is worth the small change.
- *
- * Patches for many common CD programs (provided by David A. van Leeuwen)
- * can be found at: ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/
