+# 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().init()
+# c = Cdplayer().init(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.
