longDescription = ''
The Ncurses (new curses) library is a free software emulation of
curses in System V Release 4.0, and more. It uses Terminfo
format, supports pads and color and multiple highlights and
forms characters and function-key mapping, and has all the other
SYSV-curses enhancements over BSD Curses.
The ncurses code was developed under GNU/Linux. It has been in
use for some time with OpenBSD as the system curses library, and
on FreeBSD and NetBSD as an external package. It should port
easily to any ANSI/POSIX-conforming UNIX. It has even been
ported to OS/2 Warp!
