The rOCCI Client

The OCCI gem includes a client you can use directly from shell with the following auth methods: x509 (with --password, --user-cred and --ca-path), basic (with --username and --password), digest (with --username and --password), none. If you won't set a password using --password, the client will ask for it later on.
