      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!
