+  A small helper class which blocks an asynchronous operation (e.g. a KIO request)
+  so that it can be used in a synchronous environment.
+
+  Example:
+
+    ...
+
+    Synchronizer mSynchronizer;
+
+    ...
+
+    job = TDEIO::file_copy( url, file, -1, true );
+    connect( job, TQT_SIGNAL( result( TDEIO::Job * ) ),
+             TQT_SLOT( slotResult( TDEIO::Job * ) ) );
+
+    mSynchronizer.start(); // will block here until the slot was called
+    ...
+
+
+    void slotResult( TDEIO::Job* )
+    {
+      mSynchronizer.stop();
+    }
