this README file. Alternatively, the latest version of the .xpi file is hosted in Amazon
S3 at the following URL:

  http://s3.amazonaws.com/ec2-downloads/ec2ui.xpi

If you visit the link above using Mozilla Firefox you will be prompted regarding the
installation of the extension.

Prerequisites:

This extension requires Mozilla Firefox version 1.5.0 or later.

Source Code:

The .xpi file is really just a renamed ZIP archive. Your garden variety ZIP utilities can be 
used to unzip it. Within this archive you will find a file named ec2ui.jar. This is also just
a renamed JAR archive so you can explore it in the same way. This JAR file contains the bulk
of the interesting source code. Highlights include:

  content/ec2ui/client.js
    This file contains the logic to construct and sign requests to Amazon EC2.

  content/ec2ui/controller.js
    This file wraps client.js and includes logic to unpack Amazon EC2 responses.
