// This class consists of one main member function,                     //
// BrowseForServiceType(), that looks for the service.                  //
// The rest of the class wraps the various bits of Bonjour service      //
// browser. The static callback function is marked with the DNSSD_API   //
// macro to make sure that the callback has the correct calling         //
// convention on Windows.                                               //

// Bonjour works out-of-the-box on MacOS X. On Linux you have to        //
// install the Avahi package and run the avahi-daemon. To compile       //
// these classes and run Avahi on Linux you need to install the:        //
//    avahi                                                             //
