+// About: Support and Testing
+// 
+// Information about what version or versions of jQuery this plugin has been
+// tested with, what browsers it has been tested in, and where the unit tests
+// reside (so you can test it yourself).
+// 
+// jQuery Versions - 1.2.6, 1.3.2, 1.4.1, 1.4.2
+// Browsers Tested - Internet Explorer 6-8, Firefox 2-4, Chrome 5-6, Safari 3.2-5,
+//                   Opera 9.6-10.60, iPhone 3.1, Android 1.6-2.2, BlackBerry 4.6-5.
+// Unit Tests      - http://benalman.com/code/projects/jquery-hashchange/unit/
+// 
+// About: Known issues
+// 
+// While this jQuery hashchange event implementation is quite stable and
+// robust, there are a few unfortunate browser bugs surrounding expected
+// hashchange event-based behaviors, independent of any JavaScript
+// window.onhashchange abstraction. See the following examples for more
+// information:
+// 
+// Chrome: Back Button - http://benalman.com/code/projects/jquery-hashchange/examples/bug-chrome-back-button/
+// Firefox: Remote XMLHttpRequest - http://benalman.com/code/projects/jquery-hashchange/examples/bug-firefox-remote-xhr/
+// WebKit: Back Button in an Iframe - http://benalman.com/code/projects/jquery-hashchange/examples/bug-webkit-hash-iframe/
+// Safari: Back Button from a different domain - http://benalman.com/code/projects/jquery-hashchange/examples/bug-safari-back-from-diff-domain/
+// 
+// Also note that should a browser natively support the window.onhashchange 
+// event, but not report that it does, the fallback polling loop will be used.
+// 
+// About: Release History
+// 
+// 1.3   - (7/21/2010) Reorganized IE6/7 Iframe code to make it more
+//         "removable" for mobile-only development. Added IE6/7 document.title
+//         support. Attempted to make Iframe as hidden as possible by using
+//         techniques from http://www.paciellogroup.com/blog/?p=604. Added 
+//         support for the "shortcut" format $(window).hashchange( fn ) and
+//         $(window).hashchange() like jQuery provides for built-in events.
+//         Renamed jQuery.hashchangeDelay to <jQuery.fn.hashchange.delay> and
+//         lowered its default value to 50. Added <jQuery.fn.hashchange.domain>
+//         and <jQuery.fn.hashchange.src> properties plus document-domain.html
+//         file to address access denied issues when setting document.domain in
+//         IE6/7.
+// 1.2   - (2/11/2010) Fixed a bug where coming back to a page using this plugin
+//         from a page on another domain would cause an error in Safari 4. Also,
+//         IE6/7 Iframe is now inserted after the body (this actually works),
+//         which prevents the page from scrolling when the event is first bound.
+//         Event can also now be bound before DOM ready, but it won't be usable
+//         before then in IE6/7.
+// 1.1   - (1/21/2010) Incorporated document.documentMode test to fix IE8 bug
+//         where browser version is incorrectly reported as 8.0, despite
+//         inclusion of the X-UA-Compatible IE=EmulateIE7 meta tag.
+// 1.0   - (1/9/2010) Initial Release. Broke out the jQuery BBQ event.special
+//         window.onhashchange functionality into a separate plugin for users
+//         who want just the basic event & back button support, without all the
+//         extra awesomeness that BBQ provides. This plugin will be included as
+//         part of jQuery BBQ, but also be available separately.

+  // Method: jQuery.fn.hashchange
+  // 
+  // Bind a handler to the window.onhashchange event or trigger all bound
+  // window.onhashchange event handlers. This behavior is consistent with
+  // jQuery's built-in event handlers.
+  // 
+  // Usage:
+  // 
+  // > jQuery(window).hashchange( [ handler ] );
+  // 
+  // Arguments:
+  // 
+  //  handler - (Function) Optional handler to be bound to the hashchange
+  //    event. This is a "shortcut" for the more verbose form:
+  //    jQuery(window).bind( 'hashchange', handler ). If handler is omitted,
+  //    all bound window.onhashchange event handlers will be triggered. This
+  //    is a shortcut for the more verbose
+  //    jQuery(window).trigger( 'hashchange' ). These forms are described in
+  //    the <hashchange event> section.
+  // 
+  // Returns:
+  // 
+  //  (jQuery) The initial jQuery collection of elements.
+  
+  // Allow the "shortcut" format $(elem).hashchange( fn ) for binding and
+  // $(elem).hashchange() for triggering, like jQuery does for built-in events.
+  $.fn[ str_hashchange ] = function( fn ) {

+  };
+  
+  // Property: jQuery.fn.hashchange.delay
+  // 
+  // The numeric interval (in milliseconds) at which the <hashchange event>
+  // polling loop executes. Defaults to 50.
+  
+  // Property: jQuery.fn.hashchange.domain
+  // 
+  // If you're setting document.domain in your JavaScript, and you want hash
+  // history to work in IE6/7, not only must this property be set, but you must
+  // also set document.domain BEFORE jQuery is loaded into the page. This
+  // property is only applicable if you are supporting IE6/7 (or IE8 operating
+  // in "IE7 compatibility" mode).
+  // 
+  // In addition, the <jQuery.fn.hashchange.src> property must be set to the
+  // path of the included "document-domain.html" file, which can be renamed or
+  // modified if necessary (note that the document.domain specified must be the
+  // same in both your main JavaScript as well as in this file).
+  // 
+  // Usage:
+  // 
+  // jQuery.fn.hashchange.domain = document.domain;
+  
+  // Property: jQuery.fn.hashchange.src
+  // 
+  // If, for some reason, you need to specify an Iframe src file (for example,
+  // when setting document.domain as in <jQuery.fn.hashchange.domain>), you can
+  // do so using this property. Note that when using this property, history
+  // won't be recorded in IE6/7 until the Iframe src file loads. This property
+  // is only applicable if you are supporting IE6/7 (or IE8 operating in "IE7
+  // compatibility" mode).
+  // 
+  // Usage:
+  // 
+  // jQuery.fn.hashchange.src = 'path/to/file.html';
+  
+  $.fn[ str_hashchange ].delay = 50;
+  /*
+  $.fn[ str_hashchange ].domain = null;
+  $.fn[ str_hashchange ].src = null;
+  */
+  
+  // Event: hashchange event
+  // 
+  // Fired when location.hash changes. In browsers that support it, the native
+  // HTML5 window.onhashchange event is used, otherwise a polling loop is
+  // initialized, running every <jQuery.fn.hashchange.delay> milliseconds to
+  // see if the hash has changed. In IE6/7 (and IE8 operating in "IE7
+  // compatibility" mode), a hidden Iframe is created to allow the back button
+  // and hash-based history to work.
+  // 
+  // Usage as described in <jQuery.fn.hashchange>:
+  // 
+  // > // Bind an event handler.
+  // > jQuery(window).hashchange( function(e) {
+  // >   var hash = location.hash;
+  // >   ...
+  // > });
+  // > 
+  // > // Manually trigger the event handler.
+  // > jQuery(window).hashchange();
+  // 
+  // A more verbose usage that allows for event namespacing:
+  // 
+  // > // Bind an event handler.
+  // > jQuery(window).bind( 'hashchange', function(e) {
+  // >   var hash = location.hash;
+  // >   ...
+  // > });
+  // > 
+  // > // Manually trigger the event handler.
+  // > jQuery(window).trigger( 'hashchange' );
+  // 
+  // Additional Notes:
+  // 
+  // * The polling loop and Iframe are not created until at least one handler
+  //   is actually bound to the 'hashchange' event.
+  // * If you need the bound handler(s) to execute immediately, in cases where
+  //   a location.hash exists on page load, via bookmark or page refresh for
+  //   example, use jQuery(window).hashchange() or the more verbose 
+  //   jQuery(window).trigger( 'hashchange' ).
+  // * The event can be bound before DOM ready, but since it won't be usable
+  //   before then in IE6/7 (due to the necessary Iframe), recommended usage is
+  //   to bind it inside a DOM ready handler.
+  
+  // Override existing $.event.special.hashchange methods (allowing this plugin
+  // to be defined after jQuery BBQ in BBQ's source code).
+  special[ str_hashchange ] = $.extend( special[ str_hashchange ], {
+
