             <span style="font-family:monospace"><span class="command"><strong>::rivet::inspect</strong></span></span> provides introspection into the running
             configuration of Rivet. Rivet's debug command uses it in order to gain insight
             into the configuration, but it can be used in any script.

               With no argument the command returns a dictionary with 3
               keys: server, dir, user. Each key is associated to a subdictionary 
               carrying the configuration as set for that request.  In this form the command is 
               meant to support compatibility with previous versions of mod_rivet 
               where three global arrays were created to be internally used by command
