[chef] Custom Cloud Plugin for Knife

[Jek Sirex < >]

Ohai, Chefs!

I have my custom private cloud with custom API. I've implemented gem for talking to this api. Now I'm thinking about knife plugin:

knife mycloud server create ...

etc...

There is hard to find good guide how to do it. Should I copy-paste existing project, like https://github.com/opscode/knife-ec2 or start somewhere else?

Also I found https://github.com/opscode/knife-cloud 

But it hasn't any documentation or examples about how to use it. Does anyone have such examples?

Should I first extend gem fog with my cloud?

Thanks!
