Tue Sep 14 21:25:22 EST 2004
	Improved performance of the HTML extractor by avoiding parsing

	resulting in a total improvement for total extraction time for 
	running all extractors of about 50%).  Improved performance

	header before trying to locate the central directory (for 5 MB
	/dev/random time improves by a factor of about 15).  Same change
	was also applied to the OO extractor (since OO is effectively a
	zip).  Overall improvement for 5 MB /dev/random for running
	all extractors is a factor of 10 (now takes 100ms on my machine
	to run 720 times on the same 5 MB file passing that file as an
	argument; the remaining time is pretty much doing 720x mmap and

	already basically functional.  Releasing 0.3.0
