nroff terminal driving tables, help please.

[R. Alston Elec. Eng.]

Can someone help me with creatation of some new terminal/printer tables
for nroff use in usr/lib/term/tab??? I don't follow just what the source
tables tab???.c actually represent. Some of the character stuff is obvious
but twinit and twrest for example?

	Thanks in advance
