	## Example: Using Subversion 1.6.17
	#

	// This method gives you an easier way of calling super
	// when you're using Backbone in plain javascript.
	// It lets you avoid writing the constructor's name multiple
	// times. You still have to specify the name of the method.
	//
	// So instead of having to write:
	//
	// User = Backbone.Model.extend({
	// save: function(attrs) {
	// this.beforeSave(attrs);

	#!/usr/bin/env node

	var fs = require('fs');
	var jsonpath = require('JSONPath');


	if (process.argv.length<3)
	{
	console.log('usage: jsonpath json_filename json_path_expr');
	exit;
