Subject Re: [DISCUSS] Breaking out interfaces to cloud-utils or create a new artifact cloud-contract
Date Thu, 10 Jan 2013 00:26:45 GMT
I think that the contract is supposed to be in cloud-api, unfortunately a
bunch of plugins directly depend on interfaces from cloud-server as well.
The network-refactor branch has moved some interfaces out of cloud-server
into cloud-api for this purpose.
