"""This module regroups a set of structures that may be used to configure

various places of the generated web interface.

Primary view configuration

``````````````````````````

:primaryview_section:

   where to display a relation in primary view. Value may be one of:

   * 'attributes', display in the attributes section

   * 'relations', display in the relations section (below attributes)

   * 'sideboxes', display in the side boxes (beside attributes)

   * 'hidden', don't display

:primaryview_display_ctrl:

   how to display a relation in primary view. Values are dict with some of the

   following keys:

   :vid:

      identifier of a view to use to display the result set. Defaults depends on

      the section:

      * 'attributes' section: 'reledit' view

      * 'relations' section: 'autolimited' view

      * 'sideboxes' section: 'sidebox' view

   :label:

     label for the relations section or side box

   :limit:

      boolean telling if the results should be limited according to the

      configuration

   :filter:

      callback taking the related result set as argument and returning it

      filtered

   :order:

      int used to control order within a section. When not specified,

      automatically set according to order in which tags are added.

   Notice those values are only considered if the relation is in a displayed

   section (controlled by :attr:`primaryview_section`)

Index view configuration

````````````````````````

:indexview_etype_section:

   entity type category in the index/manage page. May be one of

   * 'application'

   * 'system'

   * 'schema'

   * 'subobject' (not displayed by default)

Actions box configuration

`````````````````````````

:actionbox_appearsin_addmenu:

  simple boolean relation tags used to control the "add entity" submenu.

  Relations whose rtag is True will appears, other won't.

Automatic form configuration

````````````````````````````
