File Types and Creator Codes

My reading of the Roughly Drafted article, is that the UTIs will have
all the abilities of creator codes on a per file as well as file
extension basis. The article is re-printed at Apple Insider
<http://www.appleinsider.com/articles/09/09/22/inside_snow_leopards_uti_apple_fixes_the_creator_code.html>
where they have the images large enough to read. There is a good one
on page 3 showing a hierarchy of file usages.

Since this (like creator codes) depends on software developers setting
up the right links, we need the RunRev standalone builder to start
giving us the option to define a UTI for our apps, as well as, or
instead of a creator code & file type.

Cheers,
