All I want is to take my AS3 source code files and compile them into a SWC file.
Upon inspection, the SWC files I generate end up with some kind of timeline or spite in them when I use the Flash IDE or that Flex SDK utility "compc", and it's irritating.
Flash is timeline based; so everything in Flash uses a timeline. They hide it very well in Flex, though, so it's not obvious under the hood.
To create a SWC file in Flex, you need to use the command line compiler, although it sounds like you've already done that, so I'm unclear what your issue is.
