ejects CDs and operates CD-Changers under Linux
 This little program will eject CD-ROMs (assuming your drive supports
 the CDROMEJECT ioctl). It also allows setting the autoeject feature,
 currently supported by a number of the Linux CD-ROM drivers. See the
 documentation in /usr/src/linux/Documentation for more information on
 the autoeject feature.

 On supported ATAPI/IDE multi-disc CD-ROM changers, it allows changing
 the active disc.
