Description:

cdcd takes a different approach from conventional console (or X) based
CD players, in that it doesn't keep with the display-oriented paradigm.
Conventional computer-based CD players resemble traditional physical CD
players. This is fine, if your user interface consists of 10 buttons.
However, computers have keyboards, so why not use them? Besides, it's
certainly a waste of a console or an xterm to have a traditional CD
player open anyway.
cdcd works in two ways, accepting commands directly off the command
line or in a query mode similar to other UNIX programs. To pass a
command to cdcd, simply run cdcd with the command as the arguement
(e.g. cdcd play). This is great for using cron and cdcd together to
make a CD alarm clock. Or, you can run cdcd without arguments and you
will be given the cdcd command prompt.
