-Breadcrumbs
------------
-
-Breadcrumbs are a navigation component to help the user locate himself
-along a path of entities.
-
-Display
-~~~~~~~
-
-Breadcrumbs are displayed by default in the header section (see
-:ref:`the_main_template_sections`).  With the default main template,
-the header section is composed by the logo, the application name,
-breadcrumbs and, at the most right, the login box. Breadcrumbs are
-displayed just next to the application name, thus they begin with a
-separator.
-
-Here is the header section of the CubicWeb's forge:
-
-.. image:: ../../images/breadcrumbs_header.png
-
-There are three breadcrumbs components defined in
-:mod:`cubicweb.web.views.ibreadcrumbs`:
-
-- `BreadCrumbEntityVComponent`: displayed for a result set with one line
-  if the entity is adaptable to ``IBreadCrumbsAdapter``.
-- `BreadCrumbETypeVComponent`: displayed for a result set with more than
-  one line, but with all entities of the same type which can adapt to
-  ``IBreadCrumbsAdapter``.
-- `BreadCrumbAnyRSetVComponent`: displayed for any other result set.

-Building breadcrumbs
-~~~~~~~~~~~~~~~~~~~~
-
-The ``IBreadCrumbsAdapter`` adapter is defined in the
-:mod:`cubicweb.web.views.ibreadcrumbs` module. It specifies that an
-entity which implements this interface must have a ``breadcrumbs`` and
-a ``parent_entity`` method. A default implementation for each is
-provided. This implementation expoits the ITreeAdapter.
-
-.. note::
-
-   Redefining the breadcrumbs is the hammer way to do it. Another way
-   is to define an `ITreeAdapter` adapter on an entity type. If
-   available, it will be used to compute breadcrumbs.
-
-Here is the API of the ``IBreadCrumbsAdapter`` class:
-
-.. automethod:: cubicweb.web.views.ibreadcrumbs.IBreadCrumbsAdapter.parent_entity
-.. automethod:: cubicweb.web.views.ibreadcrumbs.IBreadCrumbsAdapter.breadcrumbs
-
-If the breadcrumbs method return a list of entities, the
-``cubicweb.web.views.ibreadcrumbs.BreadCrumbView`` is used to display
-the elements.
-
-By default, for any entity, if recurs=True, breadcrumbs method returns
-a list of entities, else a list of a simple string.
-
-In order to see a hierarchical breadcrumbs, entities must have a
-``parent`` method which returns the parent entity. By default this
-method doesn't exist on entity, given that it can not be guessed.
