+This module provides the default, simple logging functionality for Catalyst.

 Your logging object is expected to provide the interface described here.

+
+Should Catalyst emit logs for this request? Will be reset at the end of 
+each request. 
+
+*NOTE* This method is not compatible with other log apis, so if you plan
+to use Log4Perl or another logger, you should call it like this:
+
+    $c->log->abort(1) if $c->log->can('abort');
+
+=head2 _send_to_log
+
+ $log->_send_to_log( @messages );
+
+This protected method is what actually sends the log information to STDERR.
+You may subclass this module and override this method to get finer control
+over the log output.
