- * An example of the 'filter()' function in ncurses, this program prompts
- * for commands and executes them (like a command shell). It illustrates
- * how ncurses can be used to implement programs that are not full-screen.
- *
- * Ncurses differs slightly from SVr4 curses. The latter does not flush its
- * state when exiting program mode, so the attributes on the command lines of
- * this program 'bleed' onto the executed commands. Rather than use the
- * reset_shell_mode() and reset_prog_mode() functions, we could invoke endwin()
- * and refresh(), but that does not work any better.
