google sitemaps generation).

This package intended for bring *canonical_path* and/or
*canonical_link* property to any traversable object. For that it
defines ICanonicalPath and ICanonicalLink interfaces, and register
basic adapters for ITraversable objects.

    `/plone/front-page` *canonical_path* will be `/front-page`.
  - *canonical_link* return absoulute url of the object.
