    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!
