Hello everybody,

	I'm facing the following problem: given two screen states
(e.g. characters on the screen, their attributes, cursor position), find
a stream of escape sequences (termcap or terminfo stuff) to turn the first
screen into the second in a way as efficient as possible.
As far as I know the curses library is not adequate for this purpose.
There's something similar in GNU emacs (18.55) but it doesn't handle the
attributes (except for the standout one on an entire row).
Furthermore the relevant code looks quite twisted with other emacs
nut-and-bolts.

	In summary: does anybody have an implementation of such a beast
that could suit my (and many other's, I guess) needs?
Thanks in advance
                     Roberto

P.S. Please respond by EMail, I'll summarize on request.
