Compiling modular AIR applications with ANT

 When compiling your main swf file, use the "link-report" property to create a list of all classes linked into the main swf.  When compiling the modules, use the "load-externs" property so that anything linked into the main swf isn't also included in the module swfs.  Since we're compiling for AIR, make sure to use configname="air" so that the compiler uses air-config.xml and not flex-config.xml when building.  To package the AIR file, you'll need to use the ant <exec> tag and call adt.bat to create the package.  The example below is an example of using these techniques to build an AIR application containing two modules.
