  13 /       Disclaimer:             This decoder is based on undocumented APIs.
  14 /                                       Therefore it is likely, if not certain, to break in future
  15 /                                       versions of BeOS. This piece of software is in no way
  16 /                                       connected to or even supported by Be, Inc.
