    summary _("Clean up signed certs, cached facts, node objects, and reports for a node stored by the puppetmaster")
    arguments _("<host1> [<host2> ...]")
    description <<-'EOT'
      Cleans up the following information a puppet master knows about a node:

      <Signed certificates> - ($vardir/ssl/ca/signed/node.domain.pem)

      <Cached facts> - ($vardir/yaml/facts/node.domain.yaml)

      <Cached node objects> - ($vardir/yaml/node/node.domain.yaml)

      <Reports> - ($vardir/reports/node.domain)

      NOTE: this action now cleans up certs via Puppet Server's CA API. A running server is required for certs to be cleaned.
