      1 # This file implements a class which forms an interface to the .cdplayerrc
      2 # file that is maintained by SGI's cdplayer program.
      3 #
      4 # Usage is as follows:
      5 #
      6 # import readcd
      7 # r = readcd.Readcd()
      8 # c = Cdplayer(r.gettrackinfo())
      9 #
     10 # Now you can use c.artist, c.title and c.track[trackno] (where trackno
     11 # starts at 1).  When the CD is not recognized, all values will be the empty
     12 # string.
     13 # It is also possible to set the above mentioned variables to new values.
     14 # You can then use c.write() to write out the changed values to the
     15 # .cdplayerrc file.
