This ruby extension makes most functions, constants, and external variables of the C library ncurses accessible from the Ruby programming language. All C functions are wrapped by module functions of a the module "Ncurses", with exactly the same name. Additionally, C functions expecting a WINDOW* as their first argument can also be called as methods of the "Ncurses::WINDOW" class. The panel library (for support of overlapping windows) is also wrapped, in the module "Ncurses::Panel".
