Hi,
Here is a patch that includes the framework for the new IBM Developer Cloud
adapter. For proof of concept, I've implemented list_nodes, list_images,
list_sizes, and list_locations. I've included the patch as an attachment,
so I may need to follow up with the patch directly embedded.
Thanks,
Eric Woods
