    The Presentations (or Views) module is somewhat crazy, since a view or
    resource cannot be identified by a single interface or name, but of four
    to five pieces of information. Conclusively, the menu let's you select an
    interface and a presentation type for which views should be found.

    By default, the resulting views exclude views that have no required
    interface ('None') or are registered to require
    'zope.interface.Interface'. To see these additional views, click on
    "Show all views".

    Once you click on "Show" you will be presented with a list of all
    applicable views. The views are sorted by layer. The views are mainly
    identified by name, since this is what you use in a URL for
    example. Information provided for each view include the required
    interface, the presentation type and the permission. If possible, the
    system also tries to extract some information from the factory, like the
    view class, the template or resource.

    Completely independent of all this, there is a link "Show Skins, Layers
    and Usages" that brings you to a simple screen that shows the mapping of
    the layers to skins and provides a list of available usages.
