-If you want something different set C<$c->log> in your application
-module, e.g.:
+This module provides the default, simple logging functionality for Catalyst.
+If you want something different set C<< $c->log >> in your application module,
+e.g.:
$c->log( MyLogger->new );
Your logging object is expected to provide the interface described here.
+Good alternatives to consider are Log::Log4Perl and Log::Dispatch.
-=head1 LOG LEVELS
+If you want to be able to log arbitrary warnings, you can do something along
+the lines of
+
+ $SIG{__WARN__} = sub { MyApp->log->warn(@_); };
-=over 4
+however this is (a) global, (b) hairy and (c) may have unexpected side effects.
+Don't say we didn't warn you.

+=head2 abort
+
+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.
