-## How to Open a Backbone.js Ticket
-
-* Do not use tickets to ask for help with (debugging) your application. Ask on
-the [mailing list](https://groups.google.com/forum/#!forum/backbonejs), 
-in the IRC channel (`#documentcloud` on Freenode), or if you understand your 
-specific problem, on [StackOverflow](http://stackoverflow.com/questions/tagged/backbone.js).
-
-* Before you open a ticket or send a pull request,
-[search](https://github.com/jashkenas/backbone/issues) for previous
-discussions about the same feature or issue. Add to the earlier ticket if you
-find one.
-
-* Before sending a pull request for a feature or bug fix, be sure to have
-[tests](http://backbonejs.org/test/).
-
-* Use the same coding style as the rest of the
-[codebase](https://github.com/jashkenas/backbone/blob/master/backbone.js).
-
-* In your pull request, do not add documentation or rebuild the minified
-`backbone-min.js` file. We'll do that before cutting a new release.
-
-* All pull requests should be made to the `master` branch.

-              <p>Backbone Views are almost more convention than they are actual code. A View
-is simply a JavaScript object that represents a logical chunk of UI in the
-DOM. This might be a single item, an entire list, a sidebar or panel, or
-even the surrounding frame which wraps your whole app. Defining a chunk of
-UI as a <strong>View</strong> allows you to define your DOM events declaratively, without
-having to worry about render order ... and makes it easy for the view to
-react to specific changes in the state of your models.</p>
-<p>Creating a Backbone.View creates its initial element outside of the DOM,
-if an existing element is not provided...</p>

-              <p>Override this function to change the manner in which Backbone persists
-models to the server. You will be passed the type of request, and the
-model in question. By default, makes a RESTful Ajax request
-to the model&#39;s <code>url()</code>. Some possible customizations could be:</p>
-<ul>
-<li>Use <code>setTimeout</code> to batch rapid-fire updates into a single request.</li>
-<li>Send up the models as XML instead of JSON.</li>
-<li>Persist models via WebSockets instead of Ajax.</li>
-</ul>
-<p>Turn on <code>Backbone.emulateHTTP</code> in order to send <code>PUT</code> and <code>DELETE</code> requests
-as <code>POST</code>, with a <code>_method</code> parameter containing the true HTTP method,
-as well as all requests with the body as <code>application/x-www-form-urlencoded</code>
-instead of <code>application/json</code> with the model in a param named <code>model</code>.
-Useful when interfacing with server-side languages like <strong>PHP</strong> that make
-it difficult to read the body of <code>PUT</code> requests.</p>

-    <h2 id="introduction">Introduction</h2>
-
-    <p>
-      When working on a web application that involves a lot of JavaScript, one
-      of the first things you learn is to stop tying your data to the DOM. It's all
-      too easy to create JavaScript applications that end up as tangled piles of
-      jQuery selectors and callbacks, all trying frantically to keep data in
-      sync between the HTML UI, your JavaScript logic, and the database on your
-      server. For rich client-side applications, a more structured approach
-      is often helpful.
-    </p>
-
-    <p>
-      With Backbone, you represent your data as
-      <a href="#Model">Models</a>, which can be created, validated, destroyed,
-      and saved to the server. Whenever a UI action causes an attribute of
-      a model to change, the model triggers a <i>"change"</i> event; all
-      the <a href="#View">Views</a> that display the model's state can be notified of the
-      change, so that they are able to respond accordingly, re-rendering themselves with
-      the new information. In a finished Backbone app, you don't have to write the glue
-      code that looks into the DOM to find an element with a specific <i>id</i>,
-      and update the HTML manually
-      &mdash; when the model changes, the views simply update themselves.
-    </p>
-
-    <p>
-      Philosophically, Backbone is an attempt to discover the minimal set
-      of data-structuring (models and collections) and user interface (views
-      and URLs) primitives that are generally useful when building web applications with
-      JavaScript. In an ecosystem where overarching, decides-everything-for-you
-      frameworks are commonplace, and many libraries require your site to be 
-      reorganized to suit their look, feel, and default behavior — Backbone should
-      continue to be a tool that gives you the <i>freedom</i> to design the full
-      experience of your web application.
-    </p>
-
-    <p>
-      If you're new here, and aren't yet quite sure what Backbone is for, start by
-      browsing the <a href="#examples">list of Backbone-based projects</a>.
-    </p>

-
-    <h2 id="upgrading">Upgrading to 1.0</h2>
-
-    <p>
-      Backbone <b>1.0</b> should be a fairly painless upgrade from the <b>0.9</b>
-      series. If you're upgrading from an older version, be sure to check out the
-      <a href="#changelog">change log</a>. In brief, a few of the larger breaking
-      changes are:
-    </p>
-
-    <ul>
-      <li>
-        If you want to smartly update the contents of a Collection,
-        adding new models, removing missing ones, and merging those already present,
-        you now call <a href="#Collection-set">set</a> (previously named "update"),
-        a similar operation to calling <tt>set</tt> on a Model. This is now the
-        default when you call <a href="#Collection-fetch">fetch</a> on a collection.
-        To get the old behavior, pass <tt>{reset: true}</tt>.
-      </li>
-      <li>
-        If you have characters in your URL segments that require URL encoding,
-        Backbone will now decode them for you (normalizing the behavior
-        cross-browser) before your route handlers receive them as arguments.
-      </li>
-      <li>
-        In <b>0.9.x</b>, Backbone events gained two new methods:
-        <a href="#Events-listenTo">listenTo</a> and
-        <a href="#Events-stopListening">stopListening</a>, which make it easier
-        to create Views that have all of their observers unbound when you
-        want to <a href="#View-remove">remove</a> the view.
-      </li>
-      <li>
-        Model validation is now only enforced by default in
-        <a href="#Model-save">save</a> &mdash; not in
-        <a href="#Model-set">set</a> unless the <tt>{validate:true}</tt>
-        option is passed. Model validation now fires an <tt>"invalid"</tt> event instead of
-        <tt>"error"</tt>.
-      </li>
-    </ul>
-
-    <h2 id="Events">Backbone.Events</h2>
-
-    <p>
-      <b>Events</b> is a module that can be mixed in to any object, giving the
-      object the ability to bind and trigger custom named events. Events do not
-      have to be declared before they are bound, and may take passed arguments.
-      For example:
-    </p>
-
-<pre class="runnable">
-var object = {};
-
-_.extend(object, Backbone.Events);
-
-object.on("alert", function(msg) {
-  alert("Triggered " + msg);
-});
-
-object.trigger("alert", "an event");
-</pre>
-
-    <p>
-      For example, to make a handy event dispatcher that can coordinate events
-      among different areas of your application: <tt>var dispatcher = _.clone(Backbone.Events)</tt>
-    </p>
-
-    <p id="Events-on">
-      <b class="header">on</b><code>object.on(event, callback, [context])</code><span class="alias">Alias: bind</span>
-      <br />
-      Bind a <b>callback</b> function to an object. The callback will be invoked
-      whenever the <b>event</b> is fired.
-      If you have a large number of different events on a page, the convention is to use colons to
-      namespace them: <tt>"poll:start"</tt>, or <tt>"change:selection"</tt>.
-      The event string may also be a space-delimited list of several events...
-    </p>
-
-<pre>
-book.on("change:title change:author", ...);
-</pre>
-
-    <p>
-      To supply a <b>context</b> value for <tt>this</tt> when the callback is invoked,
-      pass the optional third argument: <tt>model.on('change', this.render, this)</tt>
-    </p>
-
-    <p>
-      Callbacks bound to the special
-      <tt>"all"</tt> event will be triggered when any event occurs, and are passed
-      the name of the event as the first argument. For example, to proxy all events
-      from one object to another:
-    </p>
-
-<pre>
-proxy.on("all", function(eventName) {
-  object.trigger(eventName);
-});
-</pre>
-
-    <p>
-      All Backbone event methods also support an event map syntax, as an alternative
-      to positional arguments:
-    </p>
-
-<pre>
-book.on({
-  "change:title": titleView.update,
-  "change:author": authorPane.update,
-  "destroy": bookView.remove
-});
-</pre>
-
-    <p id="Events-off">
-      <b class="header">off</b><code>object.off([event], [callback], [context])</code><span class="alias">Alias: unbind</span>
-      <br />
-      Remove a previously-bound <b>callback</b> function from an object. If no
-      <b>context</b> is specified, all of the versions of the callback with
-      different contexts will be removed. If no
-      callback is specified, all callbacks for the <b>event</b> will be
-      removed. If no event is specified, callbacks for <i>all</i> events
-      will be removed.
-    </p>
-
-<pre>
-// Removes just the `onChange` callback.
-object.off("change", onChange);
-
-// Removes all "change" callbacks.
-object.off("change");
-
-// Removes the `onChange` callback for all events.
-object.off(null, onChange);
-
-// Removes all callbacks for `context` for all events.
-object.off(null, null, context);
-
-// Removes all callbacks on `object`.
-object.off();
-</pre>
-
-    <p>
-      Note that calling <tt>model.off()</tt>, for example, will indeed remove <i>all</i> events
-      on the model &mdash; including events that Backbone uses for internal bookkeeping.
-    </p>
-
-    <p id="Events-trigger">
-      <b class="header">trigger</b><code>object.trigger(event, [*args])</code>
-      <br />
-      Trigger callbacks for the given <b>event</b>, or space-delimited list of events.
-      Subsequent arguments to <b>trigger</b> will be passed along to the
-      event callbacks.
-    </p>
-
-    <p id="Events-once">
-      <b class="header">once</b><code>object.once(event, callback, [context])</code>
-      <br />
-      Just like <a href="#Events-on">on</a>, but causes the bound callback to only
-      fire once before being removed. Handy for saying "the next time that X happens, do this".
-    </p>
-
-    <p id="Events-listenTo">
-      <b class="header">listenTo</b><code>object.listenTo(other, event, callback)</code>
-      <br />
-      Tell an <b>object</b> to listen to a particular event on an <b>other</b>
-      object.  The advantage of using this form, instead of <tt>other.on(event,
-      callback, object)</tt>, is that <b>listenTo</b> allows the <b>object</b>
-      to keep track of the events, and they can be removed all at once later
-      on.  The <b>callback</b> will always be called with <b>object</b> as
-      context.
-    </p>
-
-<pre>
-view.listenTo(model, 'change', view.render);
-</pre>
-
-    <p id="Events-stopListening">
-      <b class="header">stopListening</b><code>object.stopListening([other], [event], [callback])</code>
-      <br />
-      Tell an <b>object</b> to stop listening to events. Either call
-      <b>stopListening</b> with no arguments to have the <b>object</b> remove
-      all of its <a href="#Events-listenTo">registered</a> callbacks ... or be more
-      precise by telling it to remove just the events it's listening to on a
-      specific object, or a specific event, or just a specific callback.
-    </p>
-
-<pre>
-view.stopListening();
-
-view.stopListening(model);
-</pre>
-
-    <p id="Events-listenToOnce">
-      <b class="header">listenToOnce</b><code>object.listenToOnce(other, event, callback)</code>
-      <br />
-      Just like <a href="#Events-listenTo">listenTo</a>, but causes the bound
-      callback to only fire once before being removed.
-    </p>
-
-    <p id="Events-catalog">
-      <b class="header">Catalog of Events</b>
-      <br />
-      Here's the complete list of built-in Backbone events, with arguments.
-      You're also free to trigger your own events on Models, Collections and
-      Views as you see fit. The <tt>Backbone</tt> object itself mixes in <tt>Events</tt>,
-      and can be used to emit any global events that your application needs.

-      <b>Models</b> are the heart of any JavaScript application, containing
-      the interactive data as well as a large part of the logic surrounding it:
-      conversions, validations, computed properties, and access control. You
-      extend <b>Backbone.Model</b> with your domain-specific methods, and
-      <b>Model</b> provides a basic set of functionality for managing changes.
-    </p>
-
-    <p>
-      The following is a contrived example, but it demonstrates defining a model
-      with a custom method, setting an attribute, and firing an event keyed
-      to changes in that specific attribute.
-      After running this code once, <tt>sidebar</tt> will be

-      In rare cases, if you're looking to get fancy,

-
-    <p>
-      If you pass a <tt>{collection: ...}</tt> as the <b>options</b>, the model
-      gains a <tt>collection</tt> property that will be used to indicate which
-      collection the model belongs to, and is used to help compute the model's
-      <a href="#Model-url">url</a>. The <tt>model.collection</tt> property is
-      normally created automatically when you first add a model to a collection.
-      Note that the reverse is not true, as passing this option to the constructor 
-      will not automatically add the model to the collection. Useful, sometimes.
-    </p>
-
-    <p>
-      If <tt>{parse: true}</tt> is passed as an <b>option</b>, the <b>attributes</b>

-      Change events for specific attributes are also triggered, and you can bind
-      to those as well, for example: <tt>change:title</tt>, and <tt>change:content</tt>.
-      You may also pass individual keys and values.

-    <p id="Collection-set">
-      <b class="header">set</b><code>collection.set(models, [options])</code>
-      <br />
-      The <b>set</b> method performs a "smart" update of the collection
-      with the passed list of models. If a model in the list isn't yet in the
-      collection it will be added; if the model is already in the collection
-      its attributes will be merged; and if the collection contains any models that
-      <i>aren't</i> present in the list, they'll be removed. All of the appropriate
-      <tt>"add"</tt>, <tt>"remove"</tt>, and <tt>"change"</tt> events are fired
-      as this happens. Returns the touched models in the collection.
-      If you'd like to customize the behavior, you can disable

-
-    <p>
-      "sortBy" comparator functions take a model and return a numeric or string

-      The behavior of <b>fetch</b> can be customized by using the available

-    </p>
-
-    <p>
-      <b>jQuery.ajax</b> options can also be passed directly as <b>fetch</b> options,

-      <tt>Documents.fetch({data: {page: 3}})</tt>
-    </p>

-
-    <p id="Collection-create">
-      <b class="header">create</b><code>collection.create(attributes, [options])</code>
-      <br />
-      Convenience to create a new instance of a model within a collection.
-      Equivalent to instantiating a model with a hash of attributes,
-      saving the model to the server, and adding the model to the set after being
-      successfully created. Returns the new model. If client-side validation
-      failed, the model will be unsaved, with validation errors.
-      In order for this to work, you should set the
-      <a href="#Collection-model">model</a> property of the collection.
-      The <b>create</b> method can accept either an attributes hash or an
-      existing, unsaved model object.
-    </p>
-
-    <p>
-      Creating a model will cause an immediate <tt>"add"</tt> event to be

-      sent to the server, as well as a <tt>"sync"</tt> event, once the

-    <h2 id="Router">Backbone.Router</h2>
-
-    <p>
-      Web applications often provide linkable, bookmarkable, shareable URLs for
-      important locations in the app. Until recently, hash fragments
-      (<tt>#page</tt>) were used to provide these permalinks, but with the
-      arrival of the History API, it's now possible to use standard URLs (<tt>/page</tt>).
-      <b>Backbone.Router</b> provides methods for routing client-side pages, and
-      connecting them to actions and events. For browsers which don't yet support
-      the History API, the Router handles graceful fallback and transparent
-      translation to the fragment version of the URL.
-    </p>
-
-    <p>
-      During page load, after your application has finished creating all of its routers,
-      be sure to call <tt>Backbone.history.start()</tt>, or
-      <tt>Backbone.history.start({pushState: true})</tt> to route the initial URL.
-    </p>
-
-    <p id="Router-extend">
-      <b class="header">extend</b><code>Backbone.Router.extend(properties, [classProperties])</code>
-      <br />
-      Get started by creating a custom router class. Define actions that are
-      triggered when certain URL fragments are
-      matched, and provide a <a href="#Router-routes">routes</a> hash
-      that pairs routes to actions. Note that you'll want to avoid using a
-      leading slash in your route definitions:
-    </p>
-
-<pre>
-var Workspace = Backbone.Router.extend({
-
-  routes: {
-    "help":                 "help",    // #help
-    "search/:query":        "search",  // #search/kiwis
-    "search/:query/p:page": "search"   // #search/kiwis/p7
-  },
-
-  help: function() {

-
-});
-</pre>
-
-    <p id="Router-routes">
-      <b class="header">routes</b><code>router.routes</code>
-      <br />
-      The routes hash maps URLs with parameters to functions on your router
-      (or just direct function definitions, if you prefer),
-      similar to the <a href="#View">View</a>'s <a href="#View-delegateEvents">events hash</a>.
-      Routes can contain parameter parts, <tt>:param</tt>, which match a single URL
-      component between slashes; and splat parts <tt>*splat</tt>, which can match
-      any number of URL components. Part of a route can be made optional by
-      surrounding it in parentheses <tt>(/:optional)</tt>.
-    </p>
-
-    <p>
-      For example, a route of <tt>"search/:query/p:page"</tt> will match
-      a fragment of <tt>#search/obama/p2</tt>, passing <tt>"obama"</tt>
-      and <tt>"2"</tt> to the action.
-    </p>
-
-    <p>
-      A route of <tt>"file/*path"</tt> will match
-      <tt>#file/nested/folder/file.txt</tt>, passing
-      <tt>"nested/folder/file.txt"</tt> to the action.
-    </p>
-
-    <p>
-      A route of <tt>"docs/:section(/:subsection)"</tt> will match
-      <tt>#docs/faq</tt> and <tt>#docs/faq/installing</tt>, passing
-      <tt>"faq"</tt> to the action in the first case, and passing <tt>"faq"</tt>
-      and <tt>"installing"</tt> to the action in the second.
-    </p>
-
-    <p>
-      Trailing slashes are treated as part of the URL, and (correctly) treated
-      as a unique route when accessed. <tt>docs</tt> and <tt>docs/</tt> will fire
-      different callbacks. If you can't avoid generating both types of URLs, you
-      can define a <tt>"docs(/)"</tt> matcher to capture both cases.
-    </p>
-
-    <p>
-      When the visitor presses the back button, or enters a URL, and a particular
-      route is matched, the name of the action will be fired as an
-      <a href="#Events">event</a>, so that other objects can listen to the router,
-      and be notified. In the following example, visiting <tt>#help/uploading</tt>
-      will fire a <tt>route:help</tt> event from the router.

-    <h2 id="History">Backbone.history</h2>
-
-    <p>
-      <b>History</b> serves as a global router (per frame) to handle <tt>hashchange</tt>
-      events or <tt>pushState</tt>, match the appropriate route, and trigger callbacks.
-      You shouldn't ever have to create one of these yourself since <tt>Backbone.history</tt>
-      already contains one.
-    </p>
-
-    <p>
-      <b>pushState</b> support exists on a purely opt-in basis in Backbone.
-      Older browsers that don't support <tt>pushState</tt> will continue to use
-      hash-based URL fragments, and if a hash URL is visited by a
-      <tt>pushState</tt>-capable browser, it will be transparently upgraded to
-      the true URL. Note that using real URLs requires your web server to be
-      able to correctly render those pages, so back-end changes are required
-      as well. For example, if you have a route of <tt>/documents/100</tt>,
-      your web server must be able to serve that page, if the browser
-      visits that URL directly. For full search-engine crawlability, it's best to
-      have the server generate the complete HTML for the page ... but if it's a web
-      application, just rendering the same content you would have for the root URL,
-      and filling in the rest with Backbone Views and JavaScript works fine.
-    </p>
-
-    <p id="History-start">
-      <b class="header">start</b><code>Backbone.history.start([options])</code>

-      to begin monitoring <tt>hashchange</tt> events, and dispatching routes.
-    </p>
-
-    <p>
-      To indicate that you'd like to use HTML5 <tt>pushState</tt> support in

-      If you'd like to use <tt>pushState</tt>, but have browsers that don't support

-      <tt>{hashChange: false}</tt> to the options.
-    </p>
-
-    <p>
-      If your application is not being served from the root url <tt>/</tt> of your

-
-    <p>
-      When called, if a route succeeds with a match for the current URL,

-    <h2 id="Sync">Backbone.sync</h2>
-
-    <p>
-      <b>Backbone.sync</b> is the function that Backbone calls every time it
-      attempts to read or save a model to the server. By default, it uses
-      <tt>jQuery.ajax</tt> to make a RESTful JSON request and returns a
-      <a href="http://api.jquery.com/jQuery.ajax/#jqXHR">jqXHR</a>. You can override
-      it in order to use a different persistence strategy, such as WebSockets,
-      XML transport, or Local Storage.
-    </p>
-
-    <p>
-      The method signature of <b>Backbone.sync</b> is <tt>sync(method, model, [options])</tt>
-    </p>
-
-    <ul>
-      <li><b>method</b> – the CRUD method (<tt>"create"</tt>, <tt>"read"</tt>, <tt>"update"</tt>, or <tt>"delete"</tt>)</li>
-      <li><b>model</b> – the model to be saved (or collection to be read)</li>
-      <li><b>options</b> – success and error callbacks, and all other jQuery request options</li>
-    </ul>
-
-    <p>
-      With the default implementation, when <b>Backbone.sync</b> sends up a request to save
-      a model, its attributes will be passed, serialized as JSON, and sent in the HTTP body
-      with content-type <tt>application/json</tt>. When returning a JSON response,
-      send down the attributes of the  model that have been changed by the server, and need
-      to be updated on the client. When responding to a <tt>"read"</tt> request from a collection
-      (<a href="#Collection-fetch">Collection#fetch</a>), send down an array
-      of model attribute objects.
-    </p>
-
-    <p>
-      Whenever a model or collection begins a <b>sync</b> with the server, a
-      <tt>"request"</tt> event is emitted. If the request completes successfully
-      you'll get a <tt>"sync"</tt> event, and an <tt>"error"</tt> event if not.
-    </p>
-
-    <p>
-      The <b>sync</b> function may be overriden globally as <tt>Backbone.sync</tt>,
-      or at a finer-grained level, by adding a <tt>sync</tt> function to a Backbone
-      collection or to an individual model.
-    </p>
-
-    <p>
-      The default <b>sync</b> handler maps CRUD to REST like so:
-    </p>
-
-    <ul>
-      <li><b>create &rarr; POST &nbsp; </b><tt>/collection</tt></li>
-      <li><b>read &rarr; GET &nbsp; </b><tt>/collection[/id]</tt></li>
-      <li><b>update &rarr; PUT &nbsp; </b><tt>/collection/id</tt></li>
-      <li><b>delete &rarr; DELETE &nbsp; </b><tt>/collection/id</tt></li>
-    </ul>
-
-    <p>
-      As an example, a Rails handler responding to an <tt>"update"</tt> call from
-      <tt>Backbone</tt> might look like this: <i>(In real code, never use
-      </i><tt>update_attributes</tt><i> blindly, and always whitelist the attributes
-      you allow to be changed.)</i>
-    </p>
-
-<pre>
-def update
-  account = Account.find params[:id]
-  account.update_attributes params
-  render :json => account
-end
-</pre>
-
-    <p>
-      One more tip for integrating Rails versions prior to 3.1 is to disable
-      the default namespacing for <tt>to_json</tt> calls on models by setting
-      <tt>ActiveRecord::Base.include_root_in_json = false</tt>

-
-    <p>
-      Backbone views are almost more convention than they are code &mdash; they
-      don't determine anything about your HTML or CSS for you, and can be used
-      with any JavaScript templating library.
-      The general idea is to organize your interface into logical views,
-      backed by models, each of which can be updated independently when the
-      model changes, without having to redraw the page. Instead of digging into
-      a JSON object, looking up an element in the DOM, and updating the HTML by hand,
-      you can bind your view's <tt>render</tt> function to the model's <tt>"change"</tt>
-      event &mdash; and now everywhere that
-      model data is displayed in the UI, it is always immediately up to date.
-    </p>
-
-    <p id="View-extend">
-      <b class="header">extend</b><code>Backbone.View.extend(properties, [classProperties])</code>
-      <br />
-      Get started with views by creating a custom view class. You'll want to
-      override the <a href="#View-render">render</a> function, specify your
-      declarative <a href="#View-delegateEvents">events</a>, and perhaps the
-      <tt>tagName</tt>, <tt>className</tt>, or <tt>id</tt> of the View's root
-      element.
-    </p>
-
-<pre>
-var DocumentRow = Backbone.View.extend({
-
-  tagName: "li",
-
-  className: "document-row",
-
-  events: {
-    "click .icon":          "open",
-    "click .button.edit":   "openEditDialog",
-    "click .button.delete": "destroy"
-  },
-
-  initialize: function() {
-    this.listenTo(this.model, "change", this.render);
-  },
-
-  render: function() {
-    ...
-  }
-
-});
-</pre>
-
-    <p>
-      Properties like <tt>tagName</tt>, <tt>id</tt>, <tt>className</tt>,
-      <tt>el</tt>, and <tt>events</tt> may also be defined as a function, if
-      you want to wait to define them until runtime.
-    </p>
-
-    <p id="View-constructor">
-      <b class="header">constructor / initialize</b><code>new View([options])</code>
-      <br />
-      When creating a new View, the options you pass &mdash; after being merged
-      into any default options already present on the view &mdash;
-      are attached to the view as <tt>this.options</tt> for future reference.
-      There are several special
-      options that, if passed, will be attached directly to the view:
-      <tt>model</tt>, <tt>collection</tt>,
-      <tt>el</tt>, <tt>id</tt>, <tt>className</tt>, <tt>tagName</tt> and <tt>attributes</tt>.
-      If the view defines an <b>initialize</b> function, it will be called when
-      the view is first created. If you'd like to create a view that references
-      an element <i>already</i> in the DOM, pass in the element as an option:
-      <tt>new View({el: existingElement})</tt>
-    </p>
-
-<pre>
-var doc = documents.first();
-
-new DocumentRow({
-  model: doc,
-  id: "document-row-" + doc.id
-});
-</pre>
-
-    <p id="View-el">
-      <b class="header">el</b><code>view.el</code>
-      <br />
-      All views have a DOM element at all times (the <b>el</b> property),
-      whether they've already been inserted into the page or not. In this
-      fashion, views can be rendered at any time, and inserted into the DOM all
-      at once, in order to get high-performance UI rendering with as few
-      reflows and repaints as possible. <tt>this.el</tt> is created from the
-      view's <tt>tagName</tt>, <tt>className</tt>, <tt>id</tt> and <tt>attributes</tt> properties,
-      if specified. If not, <b>el</b> is an empty <tt>div</tt>.
-    </p>
-
-<pre class="runnable">
-var ItemView = Backbone.View.extend({

-
-    <p id="View-$el">
-      <b class="header">$el</b><code>view.$el</code>

-    </p>
-
-<pre>
-view.$el.show();

-
-    <p id="View-setElement">
-      <b class="header">setElement</b><code>view.setElement(element)</code>
-      <br />
-      If you'd like to apply a Backbone view to a different DOM element, use
-      <b>setElement</b>, which will also create the cached <tt>$el</tt> reference
-      and move the view's delegated events from the old element to the new one.
-    </p>
-
-    <p id="View-attributes">
-      <b class="header">attributes</b><code>view.attributes</code>
-      <br />
-      A hash of attributes that will be set as HTML DOM element attributes on the

-      returns such a hash.
-    </p>
-
-    <p id="View-dollar">
-      <b class="header">$ (jQuery)</b><code>view.$(selector)</code>
-      <br />
-      If jQuery is included on the page, each view has a
-      <b>$</b> function that runs queries scoped within the view's element. If you use this
-      scoped jQuery function, you don't have to use model ids as part of your query
-      to pull out specific elements in a list, and can rely much more on HTML class
-      attributes. It's equivalent to running: <tt>view.$el.find(selector)</tt>
-    </p>
-
-<pre>
-ui.Chapter = Backbone.View.extend({
-  serialize : function() {
-    return {
-      title: this.$(".title").text(),

-      end:   this.$(".end-page").text()
-    };

-});
-</pre>
-
-    <p id="View-template">
-      <b class="header">template</b><code>view.template([data])</code>
-      <br />
-      While templating for a view isn't a function provided directly by Backbone,
-      it's often a nice convention to define a <b>template</b> function on your 
-      views. In this way, when rendering your view, you have convenient access to
-      instance data (<tt>this.model</tt>, <tt>options</tt>, and so on). 
-      For example, using Underscore templates:
-    </p>
-
-<pre>
-var LibraryView = Backbone.View.extend({
-  template: _.template(...)
-});
-</pre>
-
-    <p id="View-render">
-      <b class="header">render</b><code>view.render()</code>
-      <br />
-      The default implementation of <b>render</b> is a no-op. Override this
-      function with your code that renders the view template from model data,
-      and updates <tt>this.el</tt> with the new HTML. A good
-      convention is to <tt>return this</tt> at the end of <b>render</b> to
-      enable chained calls.
-    </p>
-
-<pre>
-var Bookmark = Backbone.View.extend({
-  template: _.template(...),
-  render: function() {
-    this.$el.html(this.template(this.model.attributes));
-    return this;
-  }
-});
-</pre>
-
-    <p>
-      Backbone is agnostic with respect to your preferred method of HTML templating.
-      Your <b>render</b> function could even munge together an HTML string, or use
-      <tt>document.createElement</tt> to generate a DOM tree. However, we suggest
-      choosing a nice JavaScript templating library.
-      <a href="http://github.com/janl/mustache.js">Mustache.js</a>,
-      <a href="http://github.com/creationix/haml-js">Haml-js</a>, and
-      <a href="http://github.com/sstephenson/eco">Eco</a> are all fine alternatives.
-      Because <a href="http://underscorejs.org/">Underscore.js</a> is already on the page,
-      <a href="http://underscorejs.org/#template">_.template</a>
-      is available, and is an excellent choice if you prefer simple
-      interpolated-JavaScript style templates.
-    </p>
-
-    <p>
-      Whatever templating strategy you end up with, it's nice if you <i>never</i>
-      have to put strings of HTML in your JavaScript. At DocumentCloud, we
-      use <a href="http://documentcloud.github.com/jammit/">Jammit</a> in order
-      to package up JavaScript templates stored in <tt>/app/views</tt> as part
-      of our main <tt>core.js</tt> asset package.
-    </p>
-
-    <p id="View-remove">
-      <b class="header">remove</b><code>view.remove()</code>
-      <br />
-      Removes a view from the DOM, and calls
-      <a href="#Events-stopListening">stopListening</a> to remove any bound
-      events that the view has <a href="#Events-listenTo">listenTo</a>'d.
-    </p>
-
-    <p id="View-delegateEvents">
-      <b class="header">delegateEvents</b><code>delegateEvents([events])</code>
-      <br />
-      Uses jQuery's <tt>on</tt> function to provide declarative callbacks
-      for DOM events within a view.
-      If an <b>events</b> hash is not passed directly, uses <tt>this.events</tt>
-      as the source. Events are written in the format <tt>{"event selector": "callback"}</tt>.
-      The callback may be either the name of a method on the view, or a direct
-      function body.
-      Omitting the <tt>selector</tt> causes the event to be bound to the view's
-      root element (<tt>this.el</tt>). By default, <tt>delegateEvents</tt> is called
-      within the View's constructor for you, so if you have a simple <tt>events</tt>
-      hash, all of your DOM events will always already be connected, and you will
-      never have to call this function yourself.
-    </p>
-
-    <p>
-      The <tt>events</tt> property may also be defined as a function that returns
-      an <b>events</b> hash, to make it easier to programmatically define your
-      events, as well as inherit them from parent views.
-    </p>
-
-    <p>
-      Using <b>delegateEvents</b> provides a number of advantages over manually
-      using jQuery to bind events to child elements during <a href="#View-render">render</a>. All attached
-      callbacks are bound to the view before being handed off to jQuery, so when
-      the callbacks are invoked, <tt>this</tt> continues to refer to the view object. When
-      <b>delegateEvents</b> is run again, perhaps with a different <tt>events</tt>
-      hash, all callbacks are removed and delegated afresh &mdash; useful for
-      views which need to behave differently when in different modes.
-    </p>
-

-      A view that displays a document in a search result might look
-      something like this:

-      to make hundreds of complex books — from student textbooks to travel guides and
-      programming manuals — engaging and accessible on the web. Inkling supports
-      WebGL-enabled 3D graphics, interactive assessments, social sharing,
-      and a system for running practice code right
-      in the book, all within a single page Backbone-driven app. Early on, the
-      team decided to keep the site lightweight by using only Backbone.js and
-      raw JavaScript. The result? Complete source code weighing in at a mere
-      350kb with feature-parity across the iPad, iPhone and web clients.

-
-    <p id="FAQ-why-backbone">
-      <b class="header">Why use Backbone, not [other framework X]?</b>
-      <br />
-      If your eye hasn't already been caught by the adaptability and elan on display
-      in the above <a href="#examples">list of examples</a>, we can get more specific:
-      Backbone.js aims to provide the common foundation that data-rich web applications
-      with ambitious interfaces require &mdash; while very deliberately avoiding
-      painting you into a corner by making any decisions that you're
-      better equipped to make yourself.
-    </p>
-
-    <ul>
-      <li>
-        The focus is on supplying you with
-        <a href="#Collection-Underscore-Methods">helpful methods to manipulate and
-        query your data</a>, not on HTML widgets or reinventing the JavaScript
-        object model.
-      </li>
-      <li>
-        Backbone does not force you to use a single template engine. Views can bind
-        to HTML constructed in
-        <a href="http://underscorejs.org/#template">your</a>
-        <a href="http://guides.rubyonrails.org/layouts_and_rendering.html">favorite</a>
-        <a href="http://mustache.github.com">way</a>.
-      </li>
-      <li>
-        It's smaller. There are fewer kilobytes for your browser or phone to download,
-        and less <i>conceptual</i> surface area. You can read and understand
-        the source in an afternoon.
-      </li>
-      <li>
-        It doesn't depend on stuffing application logic into your HTML.
-        There's no embedded JavaScript, template logic, or binding hookup code in
-        <tt>data-</tt> or <tt>ng-</tt> attributes, and no need to invent your own HTML tags.
-      </li>
-      <li>
-        <a href="#Events">Synchronous events</a> are used as the fundamental
-        building block, not a difficult-to-reason-about run loop, or by constantly
-        polling and traversing your data structures to hunt for changes. And if
-        you want a specific event to be asynchronous and aggregated,
-        <a href="http://underscorejs.org/#debounce">no problem</a>.
-      </li>
-      <li>
-        Backbone scales well, from <a href="http://disqus.com">embedded widgets</a>
-        to <a href="http://www.usatoday.com">massive apps</a>.
-      </li>
-      <li>
-        Backbone is a library, not a framework, and plays well with others.
-        You can embed Backbone widgets in Dojo apps without trouble, or use Backbone
-        models as the data backing for D3 visualizations (to pick two entirely
-        random examples).
-      </li>
-      <li>
-        "Two way data-binding" is avoided. While it certainly makes for a nifty
-        demo, and works for the most basic CRUD, it doesn't tend to be terribly
-        useful in your real-world app. Sometimes you want to update on
-        every keypress, sometimes on blur, sometimes when the panel is closed,
-        and sometimes when the "save" button is clicked. In almost all cases, simply
-        serializing the form to JSON is faster and easier. All that aside, if your
-        heart is set, <a href="http://rivetsjs.com">go</a>
-        <a href="http://nytimes.github.com/backbone.stickit/">for it</a>.
-      </li>
-      <li>
-        There's no built-in performance penalty for choosing to structure your
-        code with Backbone. And if you do want to optimize further, thin models and
-        templates with flexible granularity make it easy to squeeze every last
-        drop of potential performance out of, say, IE8.
-      </li>
-    </ul>
-
-    <p id="FAQ-tim-toady">
-      <b class="header">There's More Than One Way To Do It</b>
-      <br />
-      It's common for folks just getting started to treat the examples listed
-      on this page as some sort of gospel truth. In fact, Backbone.js is intended
-      to be fairly agnostic about many common patterns in client-side code.
-      For example...
-    </p>
-
-    <p>
-      <b>References between Models and Views</b> can be handled several ways.
-      Some people like to have direct pointers, where views correspond 1:1 with
-      models (<tt>model.view</tt> and <tt>view.model</tt>). Others prefer to have intermediate
-      "controller" objects that orchestrate the creation and organization of
-      views into a hierarchy. Others still prefer the evented approach, and always
-      fire events instead of calling methods directly. All of these styles work well.
-    </p>
-
-    <p>
-      <b>Batch operations</b> on Models are common, but often best handled differently
-      depending on your server-side setup. Some folks don't mind making individual
-      Ajax requests. Others create explicit resources for RESTful batch operations:
-      <tt>/notes/batch/destroy?ids=1,2,3,4</tt>. Others tunnel REST over JSON, with the
-      creation of "changeset" requests:
-    </p>
-
-<pre>
-  {
-    "create":  [array of models to create]
-    "update":  [array of models to update]
-    "destroy": [array of model ids to destroy]
-  }
-</pre>
-
-    <p>
-      <b>Feel free to define your own events.</b> <a href="#Events">Backbone.Events</a>
-      is designed so that you can mix it in to any JavaScript object or prototype.
-      Since you can use any string as an event, it's often handy to bind
-      and trigger your own custom events: <tt>model.on("selected:true")</tt> or
-      <tt>model.on("editing")</tt>
-    </p>
-
-    <p>
-      <b>Render the UI</b> as you see fit. Backbone is agnostic as to whether you
-      use <a href="http://underscorejs.org/#template">Underscore templates</a>,
-      <a href="https://github.com/janl/mustache.js">Mustache.js</a>, direct DOM
-      manipulation, server-side rendered snippets of HTML, or
-      <a href="http://jqueryui.com/">jQuery UI</a> in your <tt>render</tt> function.
-      Sometimes you'll create a view for each model ... sometimes you'll have a
-      view that renders thousands of models at once, in a tight loop. Both can be
-      appropriate in the same app, depending on the quantity of data involved,
-      and the complexity of the UI.
-    </p>
-
-    <p id="FAQ-nested">
-      <b class="header">Nested Models &amp; Collections</b>
-      <br />
-      It's common to nest collections inside of models with Backbone. For example,
-      consider a <tt>Mailbox</tt> model that contains many <tt>Message</tt> models.
-      One nice pattern for handling this is have a <tt>this.messages</tt> collection
-      for each mailbox, enabling the lazy-loading of messages, when the mailbox
-      is first opened ... perhaps with <tt>MessageList</tt> views listening for
-      <tt>"add"</tt> and <tt>"remove"</tt> events.
-    </p>
-
-<pre>
-var Mailbox = Backbone.Model.extend({
-
-  initialize: function() {
-    this.messages = new Messages;
-    this.messages.url = '/mailbox/' + this.id + '/messages';
-    this.messages.on("reset", this.updateCounts);
-  },
-
-  ...
-
-});
-
-var inbox = new Mailbox;
-
-// And then, when the Inbox is opened:
-
-inbox.messages.fetch({reset: true});
-</pre>
-
-    <p>
-      If you're looking for something more opinionated, there are a number of
-      Backbone plugins that add sophisticated associations among models,
-      <a href="https://github.com/jashkenas/backbone/wiki/Extensions%2C-Plugins%2C-Resources">available on the wiki</a>.
-    </p>
-
-    <p>
-      Backbone doesn't include direct support for nested models and collections
-      or "has many" associations because there are a number
-      of good patterns for modeling structured data on the client side, and
-      <i>Backbone should provide the foundation for implementing any of them.</i>
-      You may want to&hellip;
-    </p>
-
-    <ul>
-      <li>
-        Mirror an SQL database's structure, or the structure of a NoSQL database.
-      </li>
-      <li>
-        Use models with arrays of "foreign key" ids, and join to top level
-        collections (a-la tables).
-      </li>
-      <li>
-        For associations that are numerous, use a range of ids instead of an
-        explicit list.
-      </li>
-      <li>
-        Avoid ids, and use direct references, creating a partial object graph
-        representing your data set.
-      </li>
-      <li>
-        Lazily load joined models from the server, or lazily deserialize nested
-        models from JSON documents.
-      </li>
-    </ul>
-
-    <p id="FAQ-bootstrap">
-      <b class="header">Loading Bootstrapped Models</b>
-      <br />
-      When your app first loads, it's common to have a set of initial models that
-      you know you're going to need, in order to render the page. Instead of
-      firing an extra AJAX request to <a href="#Collection-fetch">fetch</a> them,
-      a nicer pattern is to have their data already bootstrapped into the page.
-      You can then use <a href="#Collection-reset">reset</a> to populate your
-      collections with the initial data. At DocumentCloud, in the
-      <a href="http://en.wikipedia.org/wiki/ERuby">ERB</a> template for the
-      workspace, we do something along these lines:
-    </p>
-
-<pre>
-&lt;script&gt;
-  var accounts = new Backbone.Collection;
-  accounts.reset(&lt;%= @accounts.to_json %&gt;);
-  var projects = new Backbone.Collection;
-  projects.reset(&lt;%= @projects.to_json(:collaborators => true) %&gt;);
-&lt;/script&gt;

-      <br />
-      Many JavaScript libraries are meant to be insular and self-enclosed,
-      where you interact with them by calling their public API, but never peek
-      inside at the guts. Backbone.js is <i>not</i> that kind of library.
-    </p>
-
-    <p>
-      Because it serves as a foundation for your application, you're meant to
-      extend and enhance it in the ways you see fit &mdash; the entire source
-      code is <a href="docs/backbone.html">annotated</a> to make this easier
-      for you. You'll find that there's very little there apart from core
-      functions, and most of those can be overriden or augmented should you find
-      the need. If you catch yourself adding methods to <tt>Backbone.Model.prototype</tt>,
-      or creating your own base subclass, don't worry &mdash; that's how things are
-      supposed to work.

-      <b class="header">How does Backbone relate to "traditional" MVC?</b>
-      <br />
-      Different implementations of the
-      <a href="http://en.wikipedia.org/wiki/Model–View–Controller">Model-View-Controller</a>
-      pattern tend to disagree about the definition of a controller. If it helps any, in
-      Backbone, the <a href="#View">View</a> class can also be thought of as a
-      kind of controller, dispatching events that originate from the UI, with
-      the HTML template serving as the true view. We call it a View because it
-      represents a logical chunk of UI, responsible for the contents of a single
-      DOM element.
-    </p>
-
-    <p>
-      Comparing the overall structure of Backbone to a server-side MVC framework
-      like <b>Rails</b>, the pieces line up like so:
-    </p>
-
-    <ul>
-      <li>
-        <b>Backbone.Model</b> &ndash; Like a Rails model minus the class
-        methods. Wraps a row of data in business logic.
-      </li>
-      <li>
-        <b>Backbone.Collection</b> &ndash; A group of models on the client-side,
-        with sorting/filtering/aggregation logic.
-      </li>
-      <li>
-        <b>Backbone.Router</b> &ndash; Rails <tt>routes.rb</tt> + Rails controller
-        actions. Maps URLs to functions.
-      </li>
-      <li>
-        <b>Backbone.View</b> &ndash; A logical, re-usable piece of UI. Often,
-        but not always, associated with a model.
-      </li>
-      <li>
-        <b>Client-side Templates</b> &ndash; Rails <tt>.html.erb</tt> views,
-        rendering a chunk of HTML.
-      </li>
-    </ul>
-
-    <p id="FAQ-this">
-      <b class="header">Binding "this"</b>
-      <br />
-      Perhaps the single most common JavaScript "gotcha" is the fact that when
-      you pass a function as a callback, its value for <tt>this</tt> is lost. With
-      Backbone, when dealing with <a href="#Events">events</a> and callbacks,
-      you'll often find it useful to rely on
-      <a href="http://underscorejs.org/#bind">_.bind</a> and
-      <a href="http://underscorejs.org/#bindAll">_.bindAll</a>
-      from Underscore.js.
-    </p>
-
-    <p>
-      When binding callbacks to Backbone events, you can choose to pass an optional
-      third argument to specify the <tt>this</tt> that will be used when the
-      callback is later invoked:
-    </p>
-
-<pre>
-var MessageList = Backbone.View.extend({
-
-  initialize: function() {
-    var messages = this.collection;
-    messages.on("reset", this.render, this);
-    messages.on("add", this.addMessage, this);
-    messages.on("remove", this.removeMessage, this);
-  }
-
-});
-
-// Later, in the app...
-
-Inbox.messages.add(newMessage);

-    <p id="FAQ-rails">
-      <b class="header">Working with Rails</b>
-      <br />
-      Backbone.js was originally extracted from
-      <a href="http://www.documentcloud.org">a Rails application</a>; getting
-      your client-side (Backbone) Models to sync correctly with your server-side
-      (Rails) Models is painless, but there are still a few things to be aware of.
-    </p>
-
-    <p>
-      By default, Rails versions prior to 3.1 add an extra layer of wrapping
-      around the JSON representation of models. You can disable this wrapping
-      by setting:
-    </p>
-
-<pre>
-ActiveRecord::Base.include_root_in_json = false
-</pre>
-
-    <p>
-      ... in your configuration. Otherwise, override
-      <a href="#Model-parse">parse</a> to pull model attributes out of the
-      wrapper. Similarly, Backbone PUTs and POSTs direct JSON representations
-      of models, where by default Rails expects namespaced attributes. You can
-      have your controllers filter attributes directly from <tt>params</tt>, or
-      you can override <a href="#Model-toJSON">toJSON</a> in Backbone to add
-      the extra wrapping Rails expects.

-    <ul style="margin-top: 5px;">
-      <li>
-        Made the return values of Collection's <tt>set</tt>, <tt>add</tt>, 
-        <tt>remove</tt>, and <tt>reset</tt> more useful. Instead of returning
-        <tt>this</tt>, they now return the changed (added, removed or updated) 
-        model or list of models.
-      </li>
-      <li>
-        Backbone Views no longer attach "special" options as direct properties
-        on the view (<tt>model</tt>, <tt>attributes</tt>, <tt>className</tt>, and so on).
-      </li>
-      <li>
-        All <tt>"invalid"</tt> events now pass consistent arguments. First the
-        model in question, then the error object, then options.
-      </li>
-      <li>
-        You are no longer permitted to change the <b>id</b> of your model during
-        <tt>parse</tt>. Use <tt>idAttribute</tt> instead.
-      </li>
-      <li>
-        On the other hand, <tt>parse</tt> is now an excellent place to extract
-        and vivify incoming nested JSON into associated submodels.
-      </li>
-      <li>
-        Many tweaks, optimizations and bugfixes relating to Backbone 1.0, 
-        including URL overrides, mutation of options, bulk ordering, trailing
-        slashes, edge-case listener leaks, nested model parsing...

-    <ul style="margin-top: 5px;">
-      <li>
-        Renamed Collection's "update" to <a href="#Collection-set">set</a>, for
-        parallelism with the similar <tt>model.set()</tt>, and contrast with
-        <a href="#Collection-reset">reset</a>. It's now the default

-        like to continue using "reset", pass <tt>{reset: true}</tt>.
-      </li>
-      <li>
-        Your route handlers will now receive their URL parameters pre-decoded.
-      </li>
-      <li>

-      </li>
-      <li>
-        Added the <a href="#Collection-findWhere">findWhere</a> method to Collections,
-        similar to <a href="#Collection-where">where</a>.
-      </li>
-      <li>

-      </li>
-      <li>
-        The routes in a Router's route map may now be function literals,
-        instead of references to methods, if you like.
-      </li>
-      <li>
-        <tt>url</tt> and <tt>urlRoot</tt> properties may now be passed as options

-      <li>
-        Added <a href="#Events-listenTo">listenTo</a>

-      </li>
-      <li>
-        Added <a href="#Collection-update">update</a> (which is also available as

-      </li>
-      <li>

-      <li>
-        The <tt>Backbone</tt> object now extends <tt>Events</tt> so that you can
-        use it as a global event bus, if you like.
-      </li>
-      <li>
-        Added a <tt>"request"</tt> event to <a href="#Sync">Backbone.sync</a>,
-        which triggers whenever a request begins to be made to the server.
-        The natural complement to the <tt>"sync"</tt> event.
-      </li>
-      <li>
-        Router URLs now support optional parts via parentheses, without having
-        to use a regex.
-      </li>
-      <li>
-        Backbone events now supports <tt>once</tt>, similar to Node's <tt>once</tt>,

-      </li>
-      <li>
-        <a href="#Model-validate">Validation</a> now occurs even during "silent"

-      <li>
-        Consolidated <tt>"sync"</tt> and <tt>"error"</tt> events within

-      <li>
-        Collections now also proxy Underscore method name aliases (collect,

-      </li>
-      <li>
-        Removed <tt>getByCid</tt> from Collections. <tt>collection.get</tt> now

-      <li>
-        After fetching a model or a collection, <i>all</i> defined <tt>parse</tt>

-      </li>
-      <li>
-        Bugfix for normalizing leading and trailing slashes in the Router

-      <li>
-        Added a <tt>Backbone.ajax</tt> hook for more convenient overriding of

-      <li>
-        <tt>Collection#sort</tt> now triggers a <tt>sort</tt> event, instead
-        of a <tt>reset</tt> event.
-      </li>
-      <li>
-        Calling <tt>destroy</tt> on a Model will now return <tt>false</tt> if
-        the model <tt>isNew</tt>.
-      </li>
-      <li>
-        To set what library Backbone uses for DOM manipulation and Ajax calls,

-      </li>
-      <li>
-        Removed the <tt>Backbone.wrapError</tt> helper method. Overriding
-        <tt>sync</tt> should work better for those particular use cases.
-      </li>
-      <li>
-        To improve the performance of <tt>add</tt>, <tt>options.index</tt>
-        will no longer be set in the `add` event callback.
-        <tt>collection.indexOf(model)</tt> can be used to retrieve the index

-      </li>
-      <li>
-        For semantic and cross browser reasons, routes will now ignore search

-      </li>
-      <li>
-        <tt>Model#set</tt> no longer accepts another model as an argument.  This leads

-        both set <tt>view.el</tt> and <tt>view.$el</tt> correctly, as well as
-        re-delegating events on the new DOM element.
-      </li>
-      <li>
-        You can now bind and trigger multiple spaced-delimited events at once.
-        For example: <tt>model.on("change:name change:age", ...)</tt>
-      </li>
-      <li>
-        When you don't know the key in advance, you may now call
-        <tt>model.set(key, value)</tt> as well as <tt>save</tt>.
-      </li>
-      <li>
-        Multiple models with the same <tt>id</tt> are no longer allowed in a
-        single collection.
-      </li>
-      <li>
-        Added a <tt>"sync"</tt> event, which triggers whenever a model's state
-        has been successfully synced with the server (create, save, destroy).
-      </li>
-      <li>
-        <tt>bind</tt> and <tt>unbind</tt> have been renamed to <tt>on</tt>
-        and <tt>off</tt> for clarity, following jQuery's lead.
-        The old names are also still supported.
-      </li>
-      <li>
-        A Backbone collection's <tt>comparator</tt> function may now behave
-        either like a <a href="http://underscorejs.org/#sortBy">sortBy</a>
-        (pass a function that takes a single argument),
-        or like a <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/sort">sort</a>
-        (pass a comparator function that expects two arguments). The comparator
-        function is also now bound by default to the collection &mdash; so you
-        can refer to <tt>this</tt> within it.
-      </li>
-      <li>
-        A view's <tt>events</tt> hash may now also contain direct function
-        values as well as the string names of existing view methods.
-      </li>
-      <li>
-        Validation has gotten an overhaul &mdash; a model's <tt>validate</tt> function
-        will now be run even for silent changes, and you can no longer create
-        a model in an initially invalid state.
-      </li>
-      <li>
-        Added <tt>shuffle</tt> and <tt>initial</tt> to collections, proxied
-        from Underscore.
-      </li>
-      <li>
-        <tt>Model#urlRoot</tt> may now be defined as a function as well as a
-        value.
-      </li>
-      <li>
-        <tt>View#attributes</tt> may now be defined as a function as well as a
-        value.
-      </li>
-      <li>
-        Calling <tt>fetch</tt> on a collection will now cause all fetched JSON
-        to be run through the collection's model's <tt>parse</tt> function, if
-        one is defined.
-      </li>
-      <li>
-        You may now tell a router to <tt>navigate(fragment, {replace: true})</tt>,
-        which will either use <tt>history.replaceState</tt> or
-        <tt>location.hash.replace</tt>, in order to change the URL without adding
-        a history entry.
-      </li>
-      <li>
-        Within a collection's <tt>add</tt> and <tt>remove</tt> events, the index
-        of the model being added or removed is now available as <tt>options.index</tt>.
-      </li>
-      <li>
-        Added an <tt>undelegateEvents</tt> to views, allowing you to manually
-        remove all configured event delegations.
-      </li>
-      <li>
-        Although you shouldn't be writing your routes with them in any case &mdash;
-        leading slashes (<tt>/</tt>) are now stripped from routes.
-      </li>
-      <li>
-        Calling <tt>clone</tt> on a model now only passes the attributes
-        for duplication, not a reference to the model itself.
-      </li>
-      <li>
-        Calling <tt>clear</tt> on a model now removes the <tt>id</tt> attribute.
-      </li>
-    </ul>

-      A View's <tt>events</tt> property may now be defined as a function, as well
-      as an object literal, making it easier to programmatically define and inherit

-      If the server has already rendered everything on page load, pass
-      <tt>Backbone.history.start({silent: true})</tt> to prevent the initial route
-      from triggering. Bugfix for pushState with encoded URLs.

-      The <tt>bind</tt> function, can now take an optional third argument, to specify
-      the <tt>this</tt> of the callback function.
-      Multiple models with the same <tt>id</tt> are now allowed in a collection.
-      Fixed a bug where calling <tt>.fetch(jQueryOptions)</tt> could cause an
-      incorrect URL to be serialized.
-      Fixed a brief extra route fire before redirect, when degrading from

-      Cleanups from the 0.5.0 release, to wit: improved transparent upgrades from

-      non-modified attributes being passed to <tt>Model#initialize</tt>. Reverted

-      A large number of tiny tweaks and micro bugfixes, best viewed by looking
-      at <a href="https://github.com/jashkenas/backbone/compare/0.3.3...0.5.0">the commit diff</a>.
-      HTML5 <tt>pushState</tt> support, enabled by opting-in with:
-      <tt>Backbone.history.start({pushState: true})</tt>.
-      <tt>Controller</tt> was renamed to <tt>Router</tt>, for clarity.
-      <tt>Collection#refresh</tt> was renamed to <tt>Collection#reset</tt> to emphasize
-      its ability to both reset the collection with new models, as well as empty
-      out the collection when used with no parameters.
-      <tt>saveLocation</tt> was replaced with <tt>navigate</tt>.
-      RESTful persistence methods (save, fetch, etc.) now return the jQuery deferred
-      object for further success/error chaining and general convenience.
-      Improved XSS escaping for <tt>Model#escape</tt>.
-      Added a <tt>urlRoot</tt> option to allow specifying RESTful urls without
-      the use of a collection.
-      An error is thrown if <tt>Backbone.history.start</tt> is called multiple times.
-      <tt>Collection#create</tt> now validates before initializing the new model.
-      <tt>view.el</tt> can now be a jQuery string lookup.
-      Backbone Views can now also take an <tt>attributes</tt> parameter.
-      <tt>Model#defaults</tt> can now be a function as well as a literal attributes
-      object.

-      Backbone.js now supports <a href="http://zeptojs.com">Zepto</a>, alongside
-      jQuery, as a framework for DOM manipulation and Ajax support.
-      Implemented <a href="#Model-escape">Model#escape</a>, to efficiently handle
-      attributes intended for HTML interpolation. When trying to persist a model,
-      failed requests will now trigger an <tt>"error"</tt> event. The

-      Bugfix for IE7 + iframe-based "hashchange" events. <tt>sync</tt> may now be
-      overridden on a per-model, or per-collection basis. Fixed recursion error
-      when calling <tt>save</tt> with no changed attributes, within a

-      All <tt>"add"</tt> and <tt>"remove"</tt> events are now sent through the
-      model, so that views can listen for them without having to know about the
-      collection. Added a <tt>remove</tt> method to <a href="#View">Backbone.View</a>.
-      <tt>toJSON</tt> is no longer called at all for <tt>'read'</tt> and <tt>'delete'</tt> requests.
-      Backbone routes are now able to load empty URL fragments.

-      Backbone now has <a href="#Controller">Controllers</a> and
-      <a href="#History">History</a>, for doing client-side routing based on
-      URL fragments.
-      Added <tt>emulateHTTP</tt> to provide support for legacy servers that don't
-      do <tt>PUT</tt> and <tt>DELETE</tt>.
-      Added <tt>emulateJSON</tt> for servers that can't accept <tt>application/json</tt>
-      encoded requests.
-      Added <a href="#Model-clear">Model#clear</a>, which removes all attributes
-      from a model.
-      All Backbone classes may now be seamlessly inherited by CoffeeScript classes.

-      Instead of requiring server responses to be namespaced under a <tt>model</tt>
-      key, now you can define your own <a href="#Model-parse">parse</a> method
-      to convert responses into attributes for Models and Collections.
-      The old <tt>handleEvents</tt> function is now named
-      <a href="#View-delegateEvents">delegateEvents</a>, and is automatically
-      called as part of the View's constructor.
-      Added a <a href="#Collection-toJSON">toJSON</a> function to Collections.
-      Added <a href="#Collection-chain">Underscore's chain</a> to Collections.

-      Added a <a href="#Model-fetch">Model#fetch</a> method for refreshing the
-      attributes of single model from the server.
-      An <tt>error</tt> callback may now be passed to <tt>set</tt> and <tt>save</tt>
-      as an option, which will be invoked if validation fails, overriding the
-      <tt>"error"</tt> event.
-      You can now tell backbone to use the <tt>_method</tt> hack instead of HTTP
-      methods by setting <tt>Backbone.emulateHTTP = true</tt>.
-      Existing Model and Collection data is no longer sent up unnecessarily with
-      <tt>GET</tt> and <tt>DELETE</tt> requests. Added a <tt>rake lint</tt> task.
-      Backbone is now published as an <a href="http://npmjs.org">NPM</a> module.

-
-
-    This file creates a global JSON object containing two methods: stringify
-    and parse.
-
-        JSON.stringify(value, replacer, space)
-            value       any JavaScript value, usually an object or array.
-
-            replacer    an optional parameter that determines how object
-                        values are stringified for objects. It can be a
-                        function or an array of strings.
-
-            space       an optional parameter that specifies the indentation
-                        of nested structures. If it is omitted, the text will
-                        be packed without extra whitespace. If it is a number,
-                        it will specify the number of spaces to indent at each
-                        level. If it is a string (such as '\t' or '&nbsp;'),
-                        it contains the characters used to indent at each level.
-
-            This method produces a JSON text from a JavaScript value.
-
-            When an object value is found, if the object contains a toJSON
-            method, its toJSON method will be called and the result will be
-            stringified. A toJSON method does not serialize: it returns the
-            value represented by the name/value pair that should be serialized,
-            or undefined if nothing should be serialized. The toJSON method
-            will be passed the key associated with the value, and this will be
-            bound to the value
-
-            For example, this would serialize Dates as ISO strings.
-
-                Date.prototype.toJSON = function (key) {
-                    function f(n) {
-                        // Format integers to have at least two digits.
-                        return n < 10 ? '0' + n : n;
-                    }
-
-                    return this.getUTCFullYear()   + '-' +
-                         f(this.getUTCMonth() + 1) + '-' +
-                         f(this.getUTCDate())      + 'T' +
-                         f(this.getUTCHours())     + ':' +
-                         f(this.getUTCMinutes())   + ':' +
-                         f(this.getUTCSeconds())   + 'Z';
-                };
-
-            You can provide an optional replacer method. It will be passed the
-            key and value of each member, with this bound to the containing
-            object. The value that is returned from your method will be
-            serialized. If your method returns undefined, then the member will
-            be excluded from the serialization.
-
-            If the replacer parameter is an array of strings, then it will be
-            used to select the members to be serialized. It filters the results
-            such that only members with keys listed in the replacer array are
-            stringified.
-
-            Values that do not have JSON representations, such as undefined or
-            functions, will not be serialized. Such values in objects will be
-            dropped; in arrays they will be replaced with null. You can use
-            a replacer function to replace those with JSON values.
-            JSON.stringify(undefined) returns undefined.
-
-            The optional space parameter produces a stringification of the
-            value that is filled with line breaks and indentation to make it
-            easier to read.
-
-            If the space parameter is a non-empty string, then that string will
-            be used for indentation. If the space parameter is a number, then
-            the indentation will be that many spaces.
-
-            Example:
-
-            text = JSON.stringify(['e', {pluribus: 'unum'}]);
-            // text is '["e",{"pluribus":"unum"}]'
-
-
-            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
-            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
-
-            text = JSON.stringify([new Date()], function (key, value) {
-                return this[key] instanceof Date ?
-                    'Date(' + this[key] + ')' : value;
-            });
-            // text is '["Date(---current time---)"]'
-
-
-        JSON.parse(text, reviver)
-            This method parses a JSON text to produce an object or array.
-            It can throw a SyntaxError exception.
-
-            The optional reviver parameter is a function that can filter and
-            transform the results. It receives each of the keys and values,
-            and its return value is used instead of the original value.
-            If it returns what it received, then the structure is not modified.
-            If it returns undefined then the member is deleted.
-
-            Example:
-
-            // Parse the text. Values that look like ISO date strings will
-            // be converted to Date objects.
-
-            myData = JSON.parse(text, function (key, value) {
-                var a;
-                if (typeof value === 'string') {
-                    a =
-/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
-                    if (a) {
-                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
-                            +a[5], +a[6]));
-                    }
-                }
-                return value;
-            });
-
-            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
-                var d;
-                if (typeof value === 'string' &&
-                        value.slice(0, 5) === 'Date(' &&
-                        value.slice(-1) === ')') {
-                    d = new Date(value.slice(5, -1));

-// But just to be safe, we want to reject all unexpected forms.
-
-// We split the second stage into 4 regexp operations in order to work around
-// crippling inefficiencies in IE's and Safari's regexp engines. First we
-// replace the JSON backslash pairs with '@' (a non-JSON character). Second, we
-// replace all simple value tokens with ']' characters. Third, we delete all
-// open brackets that follow a colon or comma or that begin the text. Finally,
-// we look to see that the remaining characters are only whitespace or ']' or
-// ',' or ':' or '{' or '}'. If that is so, then the text is safe for eval.

-
-// In the third stage we use the eval function to compile the text into a
-// JavaScript structure. The '{' operator is subject to a syntactic ambiguity
-// in JavaScript: it can begin a block or an object literal. We wrap the text
-// in parens to eliminate the ambiguity.
-
-                j = eval('(' + text + ')');
