As of tonight I’ve happily updated the long idle A3M project on github.

You can check it out here:
https://github.com/pengkong/A3M-for-CodeIgniter-2.0

Also, I will be updating the official A3M guide later (as its almost 3am as I write this).

Check it out, and enjoy. Feel free to fork and offer bugs, enhancements and suggestions to make it even better!
