 This page talks about packaged apps&mdash;how
 you implement them,
 and how they're different from
 extensions and ordinary web apps.
 </p>
 
 <h2 id="overview">Overview</h2>
 
 <p>
 A packaged app is a web app
 that's bundled into a <code>.crx</code> file
 and can use Chrome extension features.
 You build a packaged app just like you build an extension,
 except that a packaged app can't include a
-<a href="browserAction.html">browser action</a> or
-<a href="pageAction.html">page action</a>.
+<a href="browserAction">browser action</a> or
+<a href="pageAction">page action</a>.
 Instead, a packaged app includes at least one HTML file
 within its <code>.crx</code> file
 that provides the app's user interface.

 <p>
 Packaged apps are a type of
 <a href="http://code.google.com/chrome/apps/">installable web app</a>&mdash;a
 web app that can be installed in Chrome.
 The other type of installable web app is a
-<a href="http://code.google.com/chrome/apps/docs/developers_guide.html">hosted app</a>,
+<a href="http://code.google.com/chrome/apps/docs/developers_guide">hosted app</a>,
 which is an ordinary web app with a bit of additional metadata.
 </p>

 If you're developing a web app for the Chrome Web Store,
 you might want to use a packaged app
 instead of a hosted app if any of the following are true:

 <h2 id="manifest"> The manifest </h2>
 
 <p>
 A packaged app's manifest can have any field
 that's available to extensions,
 except for "browser_action" and "page_action".
 In addition, a packaged app's manifest <b>must</b>
 have an "app" field.
 Here is a typical manifest for a packaged app:
 </p>
 
 <pre data-filename="manifest.json">
 {
   "name": "My Awesome Racing Game",
   "description": "Enter a world where a Vanagon can beat a Maserati",
   "version": "1",

 Packaged apps usually provide a 16x16 icon
 to be used as the favicon for
 tabs that contain app's pages.
 They also should provide a 128x128 icon,
 but not a 48x48 icon.
