Came across another Actionscript library today, called Guttershark. This one is not Flex-specific, and is targeted towards Flash web site development, much like Gaia. Note the use of ‘library’ instead of ‘framework’…I think that is a specific designation by the author to separate it out from the existing sets of frameworks out there. It is still in essence a framework, but there’s lots of individual goodies in there that aren’t dependent on using the entire library.
Taking a look at the DocumentController entry in the API docs should give you a good idea of what Guttershark is about. If you do a lot of flash web site development, it’s worth a look to check it out.
