	Thanks for the heads-up, MAtthew.  I'm much too slow to get
	all the machinations re which corporation is diddling which
	corporation or other entity (like us).  Did not know that
	mysql was actually owned by Sun.  I'd ask if there are any
	free and open databases, but what db stuff I have is invested
	heavily with mysql.  So v 60 is out.  Do you know, off-chance,
	which versions are actively being hacked on?  Nothing mission
	critical--yet--but I think v51 is the best bet for now.


	PS: to the powers-that-be: shouldn't these datapoints be make
	public front/center somewhere in ports or elsewhere that
	everyone can see? Save bandwidth... .

	This is going in my ~/.Notes file... .
