This AS2 client library for Facebook is no longer maintained.

Thanks for your interest in this project, but due to the near obsolescence of AS2 I have abandonded this project.
There are AS3 libraries available, but I am not involved in any of them.

ActionScript developers may find my latest project of interest. JASPA is an ActionScript-to-JavaScript cross-compiler written in PHP.
Write robust object-orientated applications in a strongly-typed language (modelled on AS3) and compile it into regular JavaScript to run in a web page, or any other environment that implements a JavaScript engine.

What does it do?

This collection of classes provides an interface into the public Facebook web services via Flash. Using them means you don't have to worry about correctly formatting Facebook requests or parsing responses. It provides a [growing] set of end points for making calls to Facebook API methods

Sorry that there's no further information on how to use this library. I will post a proper tutorial when I find the time.
