-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

 You can either configure the appenders and log levels manually (as above), or provide a 
 configuration file (`log4js.configure('path/to/file.json')`) explicitly, or just let log4js look for a file called `log4js.json` (it looks in the current directory first, then the require paths, and finally looks for the default config included in the same directory as the `log4js.js` file). 
 An example file can be found in `test/log4js.json`. An example config file with log rolling is in `test/with-log-rolling.json`
+You can also pass an object to the configure function, which has the same properties as the json versions.

+## connect/express logger

-patternLayout has no tests. This is mainly because I haven't found a use for it yet, 
-and am not entirely sure what it was supposed to do. It is more-or-less intact from 
-the original log4js.
+A connect/express logger has been added to log4js, by [danbell](https://github.com/danbell). This allows connect/express servers to log using log4js. See example-connect-logger.js. 
+
+    var log4js = require('./lib/log4js');

+        res.send('hello world');
+    });
+    app.listen(5000);
+
+The options object that is passed to log4js.connectLogger supports a format string the same as the connect/express logger. For example:
+
+    app.configure(function() {
+        app.use(log4js.connectLogger(logger, { level: log4js.levels.INFO, format: ':method :url' }));
