	Well, I knew if I asked around and the right places, that
	eventually i'd get an intelligent answer.  When I began
	labeling and tagging my few fn's, i realized how much work it
	was ... and that is just for us BSD'ers.  It wouldn't work on
	other systems--at least not the driver side.  But that was
	never my primary thought.  I was thinking more of the
	application area; code that you use maybe for a few hours or
	days, then pitch.  Or maybe tarbar with bzip.

	Could this be the next hundred-thousand-dollar idea?  [I'd
	say $million, but not with the global *D*epression we may be
	heading into/toward.  Seriously.  

	I realize that corporation ABC wants to wipe away corporation
	XYZ, say, but having this global, completely free/open source
	site would help both equally.  Seems to me this kind of site
	would benefit everybody and harm no one.  So the
	maintainer/dictator would probably have to be paid.  Or else
	get a free honey-glazed ham on New Years.  

	I'll check out glib.  Meanwhile there is publib.  It has some 
	pretty useful functions, some of whic h I had to do the hard
	way, then found that liw had already done them.
