*/


// ***************************************************
// * How to use UPnP framework logging facility
// * 1. define KComponentLogfile
// *     _LIT( KComponentLogfile, "AVControlServer.txt");
// * 2. if you want, define one of these macros:
// *     __FILE_LOGGING__     (logging to file)
// *     __CONSOLE_LOGGING__  (logging to console)
// * 3. have flogger in mmp-file
// *     DEBUGLIBRARY FLOGGER.LIB
// * 4. now you can use the log interface
// *     __LOG( char* strz )
// *     __LOG1( char* strz, p1 )
// *     __LOG2( char* strz, p1, p2 )
// *     __LOG3( char* strz, p1, p2, p3 )
// *     __LOG8( const TDesC8& msg )
// *     __LOG16( const TDesC16& msg )
