Parsley does not include Cairngorm. Parsley is a dependency injection framework and Caringorm 3 works out of the box with Parsley. You should probably look at parsley and cairngorm 3 websites.
There are many other frameworks as well. I like robotlegs which can also be used in presentation model approach.
The cairngorm site has only link to source but am looking for the Cairngorm.swc
Do you have any sample examples on robotlegs framework, on how to seperate model from view so that view has only the layout code. I'm talking abt something like this. (Link : http://opensource.adobe.com/wiki/display/cairngorm/SimpleSampleApplicationExplained)
public var model:ToolbarPM;
styleName="contactsAddButton" toolTip="Add Contact"
You can compile the swc yourself, in my opinion its better to use the source. There are plenty of examples on the robotlegs site, start there. In Flex 4, visual design, including layout, is responsibility of skin files.
