+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!")
