This section presents the full source code of a working sample widget
+for the Logging service.
+You can download the wgz package for this widget from
+section Example widgets.
For general information about creating widgets, see section Widget component files.
+For widget development and debugging purposes, this example writes its
+output to c:\data\jslog_widget.log using console.info.
+For instructions on how to enable logging in the Web browser for S60, see
