This command can also provision your server ("--provision/-p") so that it is

capable of hosting Co-op Cloud apps. Abra will default to expecting that you
|

have a working SSH config for the host in your ~/.ssh/config file. E.g. for

"example.com", you'll want to have something like:

Host example.com

If you have no SSH key configured for this host and are instead using password

authentication, you may pass "--ssh-auth password" to have Abra ask you for the

password. "--ask-sudo-pass" may be passed if you run your provisioning commands
