Flex Build SWF size - Tips and Tricks

Hi,

I know ANT is an option here but I am curious, are there any tips and trick to getting the exported swf size down using IntelliJ.  Obviously use -debug=false but are there any other compiler arguments to compress the swf down further, cos try as I might I cant seem to match Flex Builders - Export Release Build swf size?

Cheers,

Simon
