There's one major and one minor category still unfixed: doctests are the major category (and I hope to be able to augment the refactoring tool to refactor bona fide doctests soon); other code generating print statements in strings is the minor category. (Oh, and I don't know if the compiler package works.)

# 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.
|
|
|
|
