   5 -- SQL to create the initial tables for the MediaWiki database.
   6 -- This is read and executed by the install script; you should
   7 -- not have to run it by itself unless doing a manual install.

  10 -- General notes:
  11 --
  12 -- The comments in this and other files are
  13 -- replaced with the defined table prefix by the installer
  14 -- and updater scripts. If you are installing or running
  15 -- updates manually, you will need to manually insert the
  16 -- table prefix if any when running these scripts.

  21 -- The user table contains basic account information,
  22 -- authentication keys, etc.
  23 --
  24 -- Some multi-wiki sites may share a single central user table
  25 -- between separate wikis using the $wgSharedDB setting.
  26 --
  27 -- Note that when a external authentication plugin is used,
  28 -- user table entries still need to be created to store
  29 -- preferences and to key tracking information in the other
  30 -- tables.
