LXVII. Ncurses terminal screen control functions
½鉜
ncurses (new curses) is a free software emulation of curses in System V Rel 4.0 (and above). It uses terminfo format, supports pads, colors, multiple highlights, form characters and function key mapping. Because of the interactive nature of this library, it will be of little use for writing Web applications, but may be useful when writing scripts meant using PHP from the command line.

Ncurses is available for the following platforms:
AIX
BeOS
Cygwin
Digital Unix (aka OSF1)
