+                This URL will be resolved using the
+                ::com::sun::star::util::PathSubstitution service. That is, it is
+                allowed to include placeholders supported by that service,

+                    $(loggername) - the name of the logger
+                    $(date) - the current date
+                    $(time) - the current time
+                    $(datetime) - the current date time
+                    $(pid) - the process identifier
+                The default value here will expand to a file with the same name
+                as the logger for which the handler is used, with extension &quot;.log&quot;.
