I have started working on AS3C at the end of last year. After a quick prototype the development stagnated and I added just several fixes and tests to the code. Basically I started AS3C as a complete C# newcommer and because of that the code is very ugly.
Due to the fact that I do not have much free time to continue developing AS3C I think it is the right time to release the source-code on the one hand and to let people experiment with it on the other hand.
You can either download the sources and build AS3C manually (you will need zlib.net) or download a binary from trunk/bin/.
When using AS3C you will need the ActionScript from the SVN. Remember that you write real ActionScript code which gets translated by AS3C. There is also one undocumented and very experimental feature existing. If you run as3c.exe -optimize main.swf you could get some speed improvements if you have heavy loops using the Math class. But it could also destroy the SWF so do not forget to make a backup :o)
…ready in beta at last. ;)
but let´s see what´s it all about, anyhow.
Really too bad you don´t have the time to go with AS3C.
