jclouds Development Tools

This dir would be made up of sub-dirs that hold scripts and config that help us develop jclouds.

No release artifacts would be created from this dir or stored in this dir.
BlobStoreCli and the rest of the suggested tools are pure Java and packaged as really-executable-jars: https://github.com/andrewgaul/jclouds/commit/713af3bf4eab0c8fd049ba713b416b8f57777c70
