# Usage.
#
# Reading audio files:
-# f = au.open(file, 'r')
+# f = sunau.open(file, 'r')
# where file is either the name of a file or an open file pointer.
# The open file pointer must have methods read(), seek(), and close().
# When the setpos() and rewind() methods are not used, the seek()
# is destroyed.
#
# Writing audio files:
-# f = au.open(file, 'w')
+# f = sunau.open(file, 'w')
# where file is either the name of a file or an open file pointer.
# The open file pointer must have methods write(), tell(), seek(), and
# close().
