   -- Dynamic Debug Flags --
   -------------------------
 
   --  Flags that can be used to active various specialized debugging output
   --  information. The flags are preset to False, which corresponds to the
   --  given output being suppressed. The individual flags can be turned on
   --  using the undocumented switch dxxx where xxx is a string of letters for
   --  flags to be turned on. Documentation on the current usage of these flags
   --  is contained in the body of Debug rather than the spec, so that we don't
   --  have to recompile the world when a new debug flag is added.
