In the command line:
rhc-ctl-domain -l <rhlogin> [-p <passwd>] (-a <key-name> [-k <ssh-pubkey>] | -r <key-name> | -u <key-name> [-k <ssh-pubkey>])

It not give user a clear direction about this command can be used to destroy domain.

The output of "man rhc-ctl-domain" looks like more clear, I think they should keep insistent.
$ man rhc-ctl-domain
