 Transitive persistence / Cascade Operations
 -------------------------------------------
 
-Persisting, removing, detaching, refreshing and merging individual entities can
-become pretty cumbersome, especially when a highly interweaved object graph
-is involved. Therefore Doctrine 2 provides a
-mechanism for transitive persistence through cascading of these
-operations. Each association to another entity or a collection of
-entities can be configured to automatically cascade certain
-operations. By default, no operations are cascaded.
-
-The following cascade options exist:
-
-
--  persist : Cascades persist operations to the associated
-   entities.
--  remove : Cascades remove operations to the associated entities.
--  merge : Cascades merge operations to the associated entities.
--  detach : Cascades detach operations to the associated entities.
--  refresh : Cascades refresh operations to the associated entities.
--  all : Cascades persist, remove, merge, refresh and detach operations to
-   associated entities.
+When working with many associated entities, you sometimes don't want to "expose" all entities to your PHP application.
+Therefore Doctrine 2 provides a mechanism for transitive persistence through cascading of certain operations.
+Each association to another entity or a collection of
+entities can be configured to automatically cascade the following operations to the associated entities:
+``persist``, ``remove``, ``merge``, ``detach``, ``refresh`` or ``all``.
