-Pre-defined schemas in the library
-----------------------------------
-
-The library defines a set of entity schemas that are required by the system
-or commonly used in `CubicWeb` applications.
-Of course, you can extend those schemas if necessary.
-
-
-System schemas
-``````````````
-The available system entities are:
-
-* `EUser`, system users
-* `EGroup`, users groups
-* `EEType`, entity type
-* `ERType`, relation type
-
-* `State`, workflow state
-* `Transition`, workflow transition
-* `TrInfo`, record of a transition trafic for an entity 
-
-* `EmailAddress`, email address, used by the system to send notifications
-  to the users and also used by others optionnals schemas
-
-* `EProperty`, used to configure the application
-* `EPermission`, used to configure the security of the application
-
-* `Card`, generic documenting card
-* `Bookmark`, an entity type used to allow a user to customize his links within
-  the application
-
-(The first 'E' in some of the names is the first letter of 'Erudi', 
-`CubicWeb`'s old name; it might be changed/removed some day.)
-
-Available cubes
-```````````````
-
-An application is based on several basic cubes. In the set of available
-basic cubes we can find for example :

-* addressbook_: PhoneNumber and PostalAddress

-* basket_: Basket (like a shopping cart)
-
-* blog_: Blog (a *very* basic blog)
-
-* comment_: Comment (to attach comment threads to entities)
-
-* email_: archiving management for emails (`Email`, `Emailpart`,
-  `Emailthread`)
-
-* event_: Event (define events, display them in calendars)
-
-* file_: File (to allow users to upload and store binary or text files)
-
-* folder_: Folder (to organize things but grouping them in folders)
-
-* keyword_: Keyword (to define classification schemes)
-
-* link_: Link (to collect links to web resources)
-
-* mailinglist_: MailingList (to reference a mailing-list and the URLs
-  for its archives and its admin interface)
-
-* person_: Person (easily mixed with addressbook)
-
-* tag_: Tag (to tag anything)
-
-* task_: Task (something to be done between start and stop date)
-
-* zone_: Zone (to define places within larger places, for example a
-  city in a state in a country)
