   4    This plugin is used as SetupWizard and initializes the database with
   5    the distributed default pages from the ./init-pages directory. It
   6    gives some configuration advice, when it thinks this is necessary.
   7
   8    You need this plugin to run only once (when you first run the Wiki),
   9    afterwards you can and should comment out the include() directive which
  10    enabled it.
