    (description
     "LIRC allows computers to send and receive IR signals of many commonly
used remote controls.  The most important part of LIRC is the @code{lircd}
daemon that decodes IR signals received by the device drivers.  The second
daemon program @code{lircmd} translates IR signals to mouse movements.
The user space applications allow you to control your computer with a remote
control: you can send X events to applications, start programs and much more
on just one button press.")
