  summary "Local Puppet Certificate Authority management."

    This provides local management of the Puppet Certificate Authority.

    You can use this subcommand to sign outstanding certificate requests, list
    and manage local certificates, and inspect the state of the CA.

    description <<-TEXT
      This will list the current certificates and certificate signing requests
      in the Puppet CA.  You will also get the fingerprint, and any certificate
      verification failure reported.
