I think I've found a problem here. In the 'Flex SDK and Property Values' section, first paragraph,"If you haven't already done so, build the Apache Flex SDK first (see the README in the flex directory for details)." I searched the SDK develop branch, I only found a related README file in the develop directory. I wonder if it's a typo or just me searching the wrong directory? Ram Lee
