 This directory contains general purpose, web oriented,
 and computational biology oriented modules,  as well
 as some less general stuff associated with the Intronerator
 web site.  Initially this library was created by Jim
 Kent from 1999 to 2001.  Since then other programmers have
 also added to it.  Jim continues to make substantial
 contributions.
 
 With the exception of the gifcomp.c module, all 
 modules here are free for all use - public, private,
 or commercial. The gifcomp.c module contains code
 originally distributed by CompuServe under a similar
-"free for all" license.  However this uses the LZW
-patented by UniSys, which UniSys started enforcing
-several years after CompuServe released this module.
-The last I heard UniSys did not require a license
-for non-commercial purposes, but did require a
-license for commercial purposes. This may change
-in the future, though the patent is nearing it's
-expiration date in any case.  Commercial users
-are advised to either get a license for LZW, or
-to switch from GIF to PNG.
+"free for all" license and the Unisys LZW patent expired in 2003.
