+The template class <code>boost::initialized&lt;T&gt;</code> supports both value-initialization
+and direct-initialization, so its interface is a superset of the interface
+of <code>value_initialized&lt;T&gt;</code>: Its default-constructor 
+value-initializes the wrapped object just like the default-constructor of
+<code>value_initialized&lt;T&gt;</code>, but <code>boost::initialized&lt;T&gt;</code>
+also offers an extra <code>explicit</code>
+constructor, which direct-initializes the wrapped object by the specified value.
+<p>
+
+<code>initialized&lt;T&gt;</code> is especially useful when the wrapped
+object must be either value-initialized or direct-initialized, depending on
+runtime conditions. For example, <code>initialized&lt;T&gt;</code> could
+hold the value of a data member that may be value-initialized by some
+constructors, and direct-initialized by others.
+On the other hand, if it is known beforehand that the
+object must <i>always</i> be value-initialized, <code>value_initialized&lt;T&gt;</code>
+may be preferable. And if the object must always be
+direct-initialized, none of the two wrappers really needs to be used.
