+ (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!")
