ncurses - Emulation library of curses. The Ncurses (new curses) library is a free software emulation of curses in System V Release 4.0. 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. 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.
