Finally, what's the name of the keypair you'd like to use?

You already have the following keypairs setup:
\t#{keynames.join("\n\t")}

You can use one of these keys, or create a new one.
EOK

  key_str_help =<<-EOH
  To make a new keypair, make sure you have the ec2 tools installed. You can create a new one by typing the command:
    ec2-add-keypair

  Save this into a file in your ~/.ec2 directory. Enter the name of the keypair here.

In your clouds.rb, you can use this keypair in your clouds.

Create one for each cloud you want to use.
