Actually, I've had no particular problem with the SVr4 man pages - though
they don't go into much detail on color, there're enough working descriptions
in the terminfo database that it's not difficult to look at those, paste
the pertinent expressions into a new description and go from there.  Since
there's only a couple of flavors for ANSI- and ANSI-like terminals that are
interesting, there's not a lot to look at (no more than a few dozen terminal
types, in fact, have color in their descriptions).

The disadvantage of a set of hardcoded tables (to fill in the gaps) is that
the table is almost as frequently applied incorrectly as it is used properly.

The O'Reilly book "Termcap & Terminfo" covers the whole topic - again, except
for color.

Use 'infocmp' to see what is in a description.  This is "infocmp -1 -L xtermc"
on Solaris.  (The reverse program, tic, compiles descriptions from source).
