   * Support for value wrappers. An ODB value wrapper is a class template
-    that wraps a value type. Common examples of wrappers are smart pointers,
-    holders, and "optional value" containers such as boost::optional. A
-    wrapper can be transparent or it can handle the NULL semantics. To
-    allow the easy conversion of value types that do not support the NULL
-    semantics into the ones that do, the odb::nullable class template has
-    been added. ODB also now includes built-in support for std::auto_ptr
-    and std::tr1::shared_ptr smart pointers as value wrappers as well as
-    for boost::shared_ptr and QSharedPointer via the Boost and Qt profiles.
-    For more information, refer to Section 7.3, "NULL Value Semantics" in
-    the ODB manual.
