CRM 2011 Create an Unmanaged Solution with all the components of the default solution

Hello All.

I'm taking over a project where CRM customization was all done in the Default Solution.

Is there a way (with some XML manipulation or other trick or tool) to create an Unmanaged Solution out of the Default Solution (meaning that the Unmanaged Solution will inherit all the customized components currently in the Default Solution).

Thanks,

Frank
