Question regarding clientScript packages and scriptMap

Suppose I have this config:


'clientScript'=>array(

	'packages'=>array(

		'jquery'=>array(

			'baseUrl'=>'http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/',

			'js'=>array('jquery.min.js'),

		),

	),

),

Is it necessary to also have this:


'scriptMap'=>array(

	'jquery.js'=>false,

	'jquery.min.js'=>false,

),

?

Also do I need to set corePackages property?

Anyone got any idea?

no you can leave that out it will override

Do we also need to set ‘jquery’=>null in corePackages property?
