 is likely to have unused configuration parameters in it; any parameter that's
 valid anywhere in Puppet can be in any config file, even if it's not used.
 
 Every section can specify three special parameters: owner, group, and mode.
 These parameters affect the required permissions of any files specified after
 their specification.  Puppet will sometimes use these parameters to check its
 own configured state, so they can be used to make Puppet a bit more self-managing.
