-SUMMARY="New curses library"
-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!
-The distribution includes the library and support utilities, including a \
-terminfo compiler tic, a decompiler infocmp, clear, tput, tset, and a \
-termcap conversion tool captoinfo. Full manual pages are provided for the \
-library and tools."
