+    The ``ir_needaction_mixin`` class adds a calculated field
+    ``needaction_pending``. This function field allows to state
+    whether a given record has a needaction for the current user.
+    This is usefull if you want to customize views according to the
+    needaction feature. For example, you may want to set records in
+    bold in a list view if the current user has an action to perform
+    on the record.
