 	Again better Mime-type detection for OLE2 streams.
 
 Mon Sep 26 20:44:10 PDT 2005
 	Minor improvements to the PDF extractor:
 	- first change is to avoid outputting keywords with empty values
   	  (for now the new check is only effective when the value is seen
 	  as a string of 8-bit characters; I'm not sure how to rewrite it
 	  for the Unicode case in the if branch just above.)
         - second change is to remap PDF Creator as 'software' keyword
           instead of 'creator'.

 	Made sure extract returns error code (1) if some files could not
 	be accessed.

 	bindings into separate packages.
 	Releasing libextractor 0.5.1.
 
 Wed Jun 29 15:37:51 CEST 2005
 	Finally found out how to disable building static libs.
 	This should cut down compile time and installed size
 	by about a factor of 2 -- especially good since the
 	static version of the plugins is pretty, well, useless.
 
 Sat Jun 18 14:56:38 EST 2005

 	none of which should have been observable.

 Tue Sep 14 21:25:22 EST 2004
 	Improved performance of the HTML extractor by avoiding parsing
 	after the header (factor of 25 improvement for a 4 MB HTML file
 	resulting in a total improvement for total extraction time for
 	running all extractors of about 50%).  Improved performance
 	of the ZIP extractor for non-zip files by testing for the ZIP
 	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
 	related system calls).

 	methods that are sufficient to build a Java class to
 	access libextractor.  The API is still incomplete but
 	already basically functional.  Releasing 0.3.0
 
 Sat Apr 10 01:34:04 EST 2004
