This creates an interesting situation since Github and others 
encourage 'forking' and modifying software.  Github shows 550 search 
hits for 'libpng' (not all of which are copies) and 8 direct forks of 
Glenn's master repository.  Each 'fork' which results in some 
modification should immediately add a document which describes the 
modifications which were made since Github distributes source code via 
Git and tarball downloads.
