HumboldtJS Library is the standard library to use with HumboldtJS. It is similar in function to the playerglobal.swc in Flash and provides standard things like a DisplayObject, a Stage, EventDispatcher and a number of utility classes to deal with the DOM.
This library is essential when developing HumboldtJS applications.
Usually you will only want the bin/HumboldtJSLibrary.swc, lib/HumboldtJSDOM.swc and dom folder and drop that into your project. You can safely ignore the rest of this repository. The rest is only needed if you want to fix bugs in the standard library or expand the functionality.
Unless you want to do these things you are probably better off starting with the HumboldJSEmpty project, so check that out first.
After cloning this repository you can import the folder as an existing project in Adobe Flash Builder. This may not be needed depending on your usage scenario. Actually building the library is done by running the ant build script in the build folder.
Note that you may need to update the FLEX_HOME path in the ant build.xml
