+-- SQL to create the initial tables for the MediaWiki database.
+-- This is read and executed by the install script; you should
+-- not have to run it by itself unless doing a manual install.
+
+--
+-- General notes:
+--
+-- The comments in this and other files are
+-- replaced with the defined table prefix by the installer
+-- and updater scripts. If you are installing or running
+-- updates manually, you will need to manually insert the

+--
+-- Some multi-wiki sites may share a single central user table
+-- between separate wikis using the $wgSharedDB setting.
+--
+-- Note that when a external authentication plugin is used,
+-- user table entries still need to be created to store
+-- preferences and to key tracking information in the other
