	To All Licensees, Distributors of Any Version of BSD: 
	As you know, certain of the Berkeley Software Distribution ("BSD") 
	source code files require that further distributions of products 
	containing all or portions of the software, acknowledge within their 
	advertising materials that such products contain software developed 
	by UC Berkeley and its contributors. 

	Specifically, the provision reads: 
	" 3. All advertising materials mentioning features or use 
	  of this software must display the following acknowledgement: 
      This product includes software developed by the University of 
      California, Berkeley and its contributors." 

	Effective immediately, licensees and distributors are no longer 
	required to include the acknowledgement within advertising 
	materials. Accordingly, the foregoing paragraph of those BSD Unix 
	files containing it is hereby deleted in its entirety.
