I decided to give the asset packing a try and added:
<library name="default" type="pak" />
to project.xml. If targeting HTML5 it looks like it’s packing all .eot .woff and .svg
fonts into default.pak but apparently the SWF assets aren’t touched. There’s still an
assets subfolder containing images from the SWF and an assets.bin file.
Is there a way to bundle those SWF assets too?
