            Daffodil DB Project Announcement
            The freshhmeat.net project announcement page lists Daffodil DB as a "Shareware" license, but the Daffodil "pricing" page http://daffodilwoods.com/products/Daffodil_DB/pricing.htm says there is a royalty for each copy embedded in an application, and the developer version (which is free) is called an "Evaluation" copy. Am I misunderstanding what the conventional shareware definition is, or is this "Shareware License" label an error?
