+--  lines to the top of any file where debug logging might be needed:
+--  
+--    local dbg
+--    if moddebug then dbg=moddebug.dbg("modname") else dbg={v1=function() end,v2=function() end,v3=function() end} end
+--
+-- Then, anywhere something needs logging, use dbg.v1("message"). Or v2, or v3.
+-- There are three levels of verbosity, v1 is the lowest, v3 is the highest or
+-- most verbose and detailed.
