      "GNU Ncurses, a free software emulation of curses in SVR4 and more")
     (description
      "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!")
