    description <<-EOT
      The section of the puppet.conf configuration file to interact with.

      The three most commonly used sections are 'main', 'master', and 'agent'.
      'Main' is the default, and is used by all Puppet applications. Other
      sections can override 'main' values for specific applications --- the
      'master' section affects puppet master and puppet cert, and the 'agent'
      section affects puppet agent.

      Less commonly used is the 'user' section, which affects puppet apply. Any
      other section will be treated as the name of a legacy environment
      (a deprecated feature), and can only include the 'manifest' and
      'modulepath' settings.
