	The discussion of this so-called PD Yacc comes and goes thru
	this net, and *every time*, until I am blue in the face, I remind
	people that it is *the* UNIX yacc, broken to little pieces so
	that it could compile under DECUS C compiler. I saw this program
	eons ago, on an RSX-11 tape. Some ignorabilis decided to submit
	it to DECUS, and it did not occur to DECUS to check. [Same thing
	happened with EMPIRE sources, but DECUS got a rap from the author,
	and withdrew the sources.]

	Therefore, in order to preserve the legal integrity of the net, *it is
	crucial that this YACC be gotten rid of*, unless you enjoy risking
	your company, yourself and the net..

	There is, however, one important point: Unless a copyright violation
	is challenged, copyrights may be lost. Something for AT&T to think
	about - someone *sells* this bloody thing !!.

	But than again, I said all of this before...
