	Sigh!  I spent a week tracking down the person who I got the 
	YACC sources from, just to make sure that the source was indeed 
	in the public domain before I posted it.  I really did, I tried.  
	He lied.

	I got a message from an individual on the net who compared the
	source to the AT&T distribution.  He said that the code looked 
	a lot like the AT&T version.  I decided that I had best make 
	sure that the source was or was not AT&T proprietary.

	After much hasseling, I finally got a look at the AT&T version 
	of the source code.  Not only does it look very similar, in many 
	places it is exactly the same.  Some of the comments and code 
	have been removed/reworded/added to but that does not change 
	the fact that the source is a direct copy, or a derivative work 
	of the AT&T source.

	I have cancelled the articles that I sent out.  I urge (plead?)
	anybody that got a copy off the net to destroy it.  I have deleted 
	all copies of it that I had.

	Needless to say, I will not be posting the lex source which I got 
	from the same source that I got yacc from.

	I am sorry for the inconvience.
