description		emulation of curses in System V Release 4.0
long_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. \
				This library offers wide-character/UTF-8 support.
