cdplayer.py
# This file implements a class which forms an interface to the .cdplayerrc
# file that is maintained by SGI's cdplayer program.
#
# Usage is as follows:
#
# import readcd
# r = readcd.Readcd()
# c = Cdplayer(r.gettrackinfo())
#
# Now you can use c.artist, c.title and c.track[trackno] (where trackno
# starts at 1). When the CD is not recognized, all values will be the empty
# string.
# It is also possible to set the above mentioned variables to new values.
# You can then use c.write() to write out the changed values to the
# .cdplayerrc file.
