	// summary:
	//		CSS3 compatibility module.
	// description:
	//		This module provides to dojox/mobile support for some of the CSS3 features 
	//		in non-CSS3 browsers, such as IE or Firefox.
	//		If you require this module, when running in a non-CSS3 browser it directly 
	//		replaces some of the methods of	dojox/mobile classes, without any subclassing. 
	//		This way, HTML pages remain the same regardless of whether this compatibility 
	//		module is used or not.
	//
	//		Example of usage: 
	//		|	require([
	//		|		"dojox/mobile",
	//		|		"dojox/mobile/compat",
	//		|		...
	//		|	], function(...){
	//		|		...
	//		|	});
	//
	//		This module also loads compatibility CSS files, which have a -compat.css
	//		suffix. You can use either the `<link>` tag or `@import` to load theme
	//		CSS files. Then, this module searches for the loaded CSS files and loads
	//		compatibility CSS files. For example, if you load dojox/mobile/themes/iphone/iphone.css
	//		in a page, this module automatically loads dojox/mobile/themes/iphone/iphone-compat.css.
	//		If you explicitly load iphone-compat.css with `<link>` or `@import`,
	//		this module will not load again the already loaded file.
	//
	//		Note that, by default, compatibility CSS files are only loaded for CSS files located
	//		in a directory containing a "mobile/themes" path. For that, a matching is done using 
	//		the default pattern	"/\/mobile\/themes\/.*\.css$/". If a custom theme is not located 
	//		in a directory containing this path, the data-dojo-config needs to specify a custom 
	//		pattern using the "mblLoadCompatPattern" configuration parameter, for instance:
	//		|	data-dojo-config="mblLoadCompatPattern: /\/mycustomtheme\/.*\.css$/"
};
