Description:

setcd is a program that allows you to control the behaviour of your
Linux cdrom device. There are a number of ways you can control the
behaviour of your cdrom drive: should it try to close the tray upon
mounting a cdrom when your happened to have left the tray open, or
should it eject the tray upon unmounting the cdrom? Should it lock the
door when some process uses the cdrom or not? Should the kernel try to
ensure that there actually is a CD in the drive, and that it is of the
right type (i.e., a data CD in case of a mount, or an audio CD in case
of a play operation)?
