How can I automate build of multiple swfs from Flash Builder 4?

I'm working on a project that has a Main.fla and a Preload.fla. I am doing all the coding in Flash Builder 4. Each time I want to test I have to go to Flash CS5, publish Main.swf and then run Preload.swf. Is there a way to automate this process so I can just press the "Run Main" button inside开发者_开发知识库 Flash Builder 4 and all that is done automatically?

Use a JSFL script to compile all your fla's. Then set up the JSFL as an external tool in Flash Builder.
