Alternate ways of creating asset libraries?

[HilarioGo]

I was wondering if there are any alternate ways to build an asset library swf that works for OpenSpace, the only way that has worked has been using Flash. Is there is a way to produce a valid swf using FlashDevelop (my experiments failed but I am by no means an expert using it ) or even more ideal would be something that could be run through command prompt? Thanks for any answers!

I'm not sure how you could create an asset library by command line or even using Flash Develop, as it must contains graphics.
