Hi,

first of all, I really like this simple but powerful tool. I have tried many others but they all seemed too complex and not what I need. Composr also doesn't scratch that itch fully, but I have the feeling the code is clean enough that adding swarm support would be easily achievable. The used docker component already supports swarm so perhaps adding a "type" to the host structure and using the swarm API functions (stack, service, node) might be easy to do.

Tell me if you need help with anything. If I can I would like to help.
