Ncurses: History, Overview & License

ncurses (new curses) is a programming library for creating textual user interfaces (TUIs) that work across a wide variety of terminals. It is written in a way that attempts to optimize the commands that are sent to the terminal, to reduce the latency experienced when updating the displayed content.
