 ** ircat.c *****************************************************************
 ****************************************************************************
 *
 * ircat - prints config strings to standard output, can be used to
 * provide remote control input to scripts
 *
 * The first agrument to the program is the program name, as it
 * appears in the prog entries in .lircrc.
 *
 * For example if .lircrc contains:
 *
 * begin
 * 	prog = myprog
 * 	button = tv_p+
 * 	config = next_file
 * end
 *
 * then
 *
 * $ ircat myprog
 *
 * will print "next_file" (followed by newline) every time the
 * button tv_p+ is pressed.
