* Changed for Squeak to work with Squeak and to work on the Macintosh
* Sept 2000, by John M McIntosh johnmci@smalltalkconsulting.com
* The smalltalk code and the C code it produces is released under the
* Squeak licence. The libmpeg3 C code is co-licenced under either the Squeak licence or

	hasAudio Returns true if file has audio
	totalAudioStreams Returns total number of audio streams

	finalize Finalize the resource associated with the receiver. This message should only be sent during the finalization process. There is NO garantuee that the resource associated with the receiver hasn't been free'd before so take care that you don't run into trouble - this all may happen with interrupt priority.
