	I have a hacked up copy of the printcap code from the BSD 'lpr'
command that implements a "caplib" library - generic "termcap" capabilities.
It differs from the "standard" termcap in that it wants to know the sizes
of the buffers passed to it, and checks for overflow. It also doesn't
support the egregious tc= kludge. There's no support for grabbing the
entry out of the environment, but that shouldn't be very hard at all.
[the way BSD does that also is a kludge - getting it out of the environment
or not should be done at a higher level than in capgetent(), IE: if there
is no XXXXCAP in the environment, *then* it uses capgetent(), etc]

	If anyone wants a copy, let me know.
