Subject Re: [DISCUSS] Release Apache FlexJS 0.5.0

I'm able to get -js-compiler-option to work. It's not ideal, but I can add
it to my examples.

I can't get ADVANCED_OPTIMIZATIONS to work with asjsc at all, though. Not
even the simplest example that I can think of. No externs required.

source/Example.as:

package
{
    public class Example
    {
        public static function run():void
        {
            trace("hello world");
        }
    }
}

index.html:

<!DOCTYPE html>
<html>
<body>
<script src="bin/js-release/Example.js"></script>
<script>
Example.run();
</script>
</body>
</html>

Build command line:
asjsc Example.as

Any idea why?
