+/**
+ * Parse request bodies.
+ *
+ * By default _application/json_, _application/x-www-form-urlencoded_,
+ * and _multipart/form-data_ are supported, however you may map `connect.bodyParser.parse[contentType]`
+ * to a function receiving `(req, options, callback)`.
+ *
+ * Examples:
+ *
+ *      connect.createServer(
+ *          connect.bodyParser()
+ *        , function(req, res) {
+ *          res.end('viewing user ' + req.body.user.name);
+ *        }
+ *      );
+ *
+ *      $ curl -d 'user[name]=tj' http://localhost/
+ *      $ curl -d '{"user":{"name":"tj"}}' -H "Content-Type: application/json" http://localhost/
+ *
+ * Multipart req.files:
+ *
+ *   As a security measure files are stored in a separate object, stored
+ *   as `req.files`. This prevents attacks that may potentially alter
+ *   filenames, and depending on the application gain access to restricted files.
+ *
+ * Multipart configuration:
+ *
+ *  The `options` passed are provided to each parser function.
+ *  The _multipart/form-data_ parser merges these with formidable's
+ *  IncomingForm object, allowing you to tweak the upload directory,
+ *  size limits, etc. For example you may wish to retain the file extension
+ *  and change the upload directory:
+ *
+ *      server.use(bodyParser({ uploadDir: '/www/mysite.com/uploads' }));
+ *
+ *  View [node-formidable](https://github.com/felixge/node-formidable) for more information.
+ *
+ *  If you wish to use formidable directly within your app, and do not
+ *  desire this behaviour for multipart requests simply remove the
+ *  parser: 
+ *
+ *     delete connect.bodyParser.parse['multipart/form-data'];
+ *
+ *  Or
+ *
+ *     delete express.bodyParser.parse['multipart/form-data'];
+ *
+ * @param {Object} options
+ * @return {Function}
+ * @api public
