compiling actionscript in linux

Question

I'm working on a website that requires a flash mp3 player. I have absolutely no idea the procedures from messing with flash/actionscript/flex etc., however I need to edit the flash very slightly (I need to add two lines of code). There are a multitude of tutorials out there for setting up a flash (or flex or whatever) development environment but, as my needs are so simple, I'd like to go a little more light-weight than that (also, many seem outdated). I guess what I'm saying is I'm looking for a simple way to recompile some existing actionscript (command line is a plus!). Does anyone have a trick up their sleeve to accomplish this?

Answer 1

Download the free/opensource Flex 3 SDK. This includes an ActionScript3 compiler. Run the compiler like this:

mxmlc MyAs3File.as
