  32  * @par About Irreco
  33  * Irreco is a remote control application for Nokia Internet Tablets. With
  34  * Irreco and the help of external IR transceiver you can control IR compatible
  35  * devices like televisions, DVD players and AV Receivers. Irreco also has a
  36  * remote editor which you can use to place buttons to the screen and build the
  37  * kind of remote you want to use.
