- # 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.
