  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.

  22 -- authentication keys, etc.

  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
