+--  Registering items, entities, etc. for cleaning can be done in ***cleaner.json***
+--  in the world directory (`<world_path>/cleaner.json`). If it does not exist
+--  it will be created automatically when the server is started.
+--
+--  It is formatted as follows:
+--
+--    {
+--      "entities" :
+--      {
+--        "remove" : []
+--      },
+--      "items" :
+--      {
+--        "replace" : {}
+--      },
+--      "nodes" :
+--      {
+--        "remove" : [],
+--        "replace" : {}
+--      },
+--      "ores" :
+--      {
+--        "remove" : []
+--      }
+--    }
+--
+--  `remove` key works for nodes, entities, & ores. `replace` key works for
+--  nodes & items. Their functions are self-explanatory.
