AWS Glacier Java Command Line Tool for PHP, Python, Ruby etc

For those of us who want to access Amazon Web Services Glacier from various environments and with a variety of programming languages I have developed an open-source (Apache 2 license) java command line app which operates AWS Glacier Vaults and Archives. The app is mostly based on AWS Java SDK samples from AWS documentation, e.g. http://docs.amazonwebservices.com/amazonglacier/latest/dev/creating-vaults-sdk-java.html

This project is hosted with Google Code: http://code.google.com/p/aws-glacier-app/
How to use the app: http://code.google.com/p/aws-glacier-app/wiki/Usage
And the ZIP with all the JARs is here: http://code.google.com/p/aws-glacier-app/downloads/list
