   5  * ircat - prints config strings to standard output, can be used to
   6  * provide remote control input to scripts
   7  *
   8  * The first agrument to the program is the program name, as it
   9  * appears in the prog entries in .lircrc.
  10  *
  11  * For example if .lircrc contains:
  12  *
  13  * begin
  14  *      prog = myprog
  15  *      button = tv_p+
  16  *      config = next_file
  17  * end
  18  *
  19  * then
  20  *
  21  * $ ircat myprog
  22  *
  23  * will print "next_file" (followed by newline) every time the
  24  * button tv_p+ is pressed.
