+-- The Great Restructuring of October 2004
+-- Creates 'page', 'revision' tables and transforms the classic
+-- cur+old into a separate page+revision+text structure.
+--
+-- The pre-conversion 'old' table is renamed to 'text' and used
+-- without internal restructuring to avoid rebuilding the entire
+-- table. (This can be done separately if desired.)
+--
+-- The pre-conversion 'cur' table is now redundant and can be
+-- discarded when done.
