AS-3/Flex Dictionary weak keys

A sample source code for using a dictionary in AS-3/Flex with weak keys.
When I say new Dictionary(true), after a while all those objects, whose
only references are as the dictionary keys, will be garbage collected.
So, if run the following in debug mode, after a while, output of trace 
will be 0, from 1 initially.

Swftools : An Introduction

What is it : A bundle of tools for finding information/manipulating swfs.

Where do I get it from : Here.

Examples : 

1. Merging two swfs : 

swfcombine.exe -a swf1.swf swf2.swf -o output.swf

2. Dumping information about a swf

swfdump.exe -a some.swf

3. Finding all the exported symbols from a swf : 

swfdump.exe -a some.swf | grep -i exports

JSFL script - iterates over many flas and create swfs for individual symbols

/*
   script tested with Flash CS5,
   should work with older versions.

function universe() {
    var flaPath = "file:///../new_assets/";
    var outputDirPath = "file:///../../../code/trunk/client/game/city/resources/assets/";
    var flaFiles = FLfile.listFolder(flaPath + "*.fla", "files");
    var numFiles = flaFiles.length;
    for (var i = 0; i < numFiles; i++) {
        var flaFilePath = flaPath + flaFiles[i];
        fl.trace("reading "+flaFilePath);
        var doc = fl.openDocument(flaFilePath);
        var items = doc.library.items;
        var iLen = items.length;

            var item = items[j];

Dumping information about exported assets of a swf

swfdump.exe -a some.swf | grep -i exports

Merging swfs with swfcombie

swfcombine.exe -a first.swf second.swf -o output.swf
