+ *
+ * Examples:
+ *
+ *      connect.createServer(
+ *          connect.bodyParser()
+ *        , function(req, res) {
+ *          res.end('viewing user ' + req.body.user.name);

+ *
+ * Since both _json_ and _x-www-form-urlencoded_ are supported by
+ * default, either of the following requests would result in the response
+ * of "viewing user tj".
+ *
+ *      $ curl -d 'user[name]=tj' http://localhost/
+ *      $ curl -d '{"user":{"name":"tj"}}' -H "Content-Type: application/json" http://localhost/
