Also, for reference, I have a bundle of repositories:
The REST responder framework, useless without a driver:
http://github.com/bobmcwhirter/deltacloud-framework/tree/master
The EC2 driver for use with the framework:
http://github.com/bobmcwhirter/deltacloud-driver-ec2/tree/master
The mock driver for use with the framework:
http://github.com/bobmcwhirter/deltacloud-driver-mock/tree/master
And the Ruby client library (ultimately will be packaged as rubygem)
http://github.com/bobmcwhirter/deltacloud-client-ruby/tree/master
