-- Dynamic Debug Flags --
-------------------------
-- Thirty six 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
