+ * 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.
