This is an excellent project. Clean, neat and to the point. Plus the AVM1 files I've created with png2swf (with alpha channel intact) were the best quality results out three programs I've tested. I've noticed that there's AVM2 code in HEAD on CVS, and read about it working for pdf2swf. Does it work for png2swf too? It looked to me like it would from the code, but I only skimmed it.
I've tried to compile the current head, as my distro has 0.8 in it's repositories currently, but it doesn't like to compile on a 64-bit platform. The current download link for a compiled snapshot of HEAD on the download page seem to be broken. Any chance of getting a good link, so I can get my hands on a compiled version? :)
