+%  This predicate is called to check whether or not the contents of a given
+%	file should be available. There are three levels of access:
+%		*  public
+%		   Accessible to everyone.
+%		*  user
+%		   Accessible to registered, logged in Cliopatria users.
+%	   *  private
+%	      Accessible to no-one.
+%  The default level is private for all files. If you wish to make some files
+%  available, you must copy (not link) this file to the 'config-available' directory
+%  of your Cliopatria installation and edit the definition of file_permission/2
+%  as you see fit.
