搜了一下全文检索博客，居然发现除了在aPDF–Flex中创建并且输出PDF文件的又一个开源开发包中稍微有提到as3corelib，其他地方居然都没有，很多经常看到经常用到的很重要的东西，往往都会被忽略……呵呵，赶紧补上这一课。
ActionScript 3 Libraries实际上是一组为Flex和Flash开发者准备的ActionScript 3开源开发包，基于BSD协议，这对于商业用户来说是非常友好的。目前具体包括下面这些组件（我个人对corelib和FlexUnit较为欣赏，:) ）：
===============
corelib
===============
The corelib project consists of several basic utilities for MD5 hashing, JSON serialization, advanced string and date parsing, and more.

Authors: Christian Cantrell, Mike Chambers, Daniel Dura, Darron Schall
Dependencies: FlexUnit
===============
eBay
===============
The eBay ActionScript 3.0 library provides an interface between the eBay XML API and ActionScript 3.0. This open-source library will allow developers to create novel and innovative applications leveraging both eBay’s marketplace services and Adobe’s Flash Player 9 runtime! It is written in ActionScript 3.0, so any environment using ActionScript 3.0 can use this library, including Adobe Flex 2 and Adobe Flash Pro 9.

Authors: Charles Bihis, Darron Schall
Dependencies: corelib, FlexUnit

FlexUnit
===============
FlexUnit is a unit testing framework for Flex and ActionScript 3.0 applications. It mimics the functionality of JUnit, a Java unit testing framework, and comes with a graphical test runner.

Flickr
===============
The Flickr library is an ActionScript 3.0 API for the online photo sharing application, Flickr. It provides access to the entire Flickr API.

Mappr
===============
Mappr is a service and application that combines images from Flickr with geolocational information. The Mappr ActionScript 3.0 API gives you access to Mappr’s geo-tagged image data.

Syndication library
===============
Use the syndication library to parse Atom and all versions of RSS easily. This library hides the differences between the formats so you can parse any type of feed without having to know what kind of feed it is.
