// **************************************************************************
// *
// *  HOW TO USE THIS LOGGING FACILITY
// *
// * 1. enable log facility in the code.
// *     _LIT( KComponentLogfile, "component.txt");
// *     #include "upnplog.h"
// *
// * 2. have flogger in mmp-file
// *     DEBUGLIBRARY FLOGGER.LIB
// *
// * 3. use the log interface in the source
// *     __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 )
// *     __ASSERTD( test, file, line )
// *     __ASSERT( test, file, line )
// *     __PANICD( file, line )
// *     __PANIC( file, line )
// *
// * 4. The default logging/assertion modes are following:
// *     DEBUG build:    log to console, assertion mode on.
// *     RELEASE build:  log turned off, assertion mode off.
// *     To override this preset, you can use following macros:
// *     MACRO __UPNP_LOG_FILE          (logging to file)
// *     MACRO __UPNP_LOG_CONSOLE       (logging to console)
// *     MACRO __UPNP_LOG_OFF           (logging turned off in DEBUG build)
// *     MACRO __UPNP_DEBUG_ASSERT      (enable D-panic and D-assert)
// *     MACRO __UPNP_DEBUG_ASSERT_OFF  (disable D-panic and D-assert)
// *     in case of using logging in RELEASE build, remember to switch
// *     LIBRARY FLOGGER.LIB instead of DEBUGLIBRARY.
// *
