-Dokku
-=====
-
-This is a simple command line tool to interface with Dokku servers. This is 
-a port of my shell extension 
-[`dokku.zsh`](https://github.com/Xe/dotfiles/blob/master/.zsh/dokku.zsh) to 
-a nice Go binary.
-
-This takes a configuration file for defining multiple servers:
-
-```ini
-[server "default"]
-user = dokku
-host = panel.apps.xeserv.us
-sshkey = /.ssh/id_rsa
-```
-
-By default it will imply that the SSH key is `~/.ssh/id_rsa` and that the 
-username is `dokku`. By default the server named `default` will be used for 
-command execution.
-
-TODO
-----
-
-- [ ] Allow interactive commands
-- [ ] Directly pipe stdin and stdout to the ssh connection
