   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.
