+    \macro Q_DECLARE_TYPEINFO(Type, Flags)
+    \relates <QTypeInfo>
+
+    You can use this macro to specify information about a custom type
+    \a Type. With accurate type information, Qt's \l{Container Classes}
+    {generic containers} can choose appropriate storage methods and
+    algorithms.
+
+    \a Flags can be one of the following:
+
+    \list
+    \li \c Q_PRIMITIVE_TYPE specifies that \a Type requires no
+        operation to be performed in order to be properly destroyed,
+        and that it is possible to use memcpy() in order to create a
+        valid independent copy of an object.
+    \li \c Q_RELOCATABLE_TYPE specifies that \a Type has a constructor
+        and/or a destructor, but it can still be \e{relocated} in memory
+        by using \c memcpy().
+    \li \c Q_MOVABLE_TYPE is the same as \c Q_RELOCATABLE_TYPE. Prefer to use
+        \c Q_RELOCATABLE_TYPE in new code. Note: despite the name, this
+        has nothing to do with move constructors or C++ move semantics.
+    \li \c Q_COMPLEX_TYPE (the default) specifies that \a Type has
+       constructors and/or a destructor and that it may not be moved
+       in memory.
+    \endlist
+
+    Example of a "primitive" type:
+
+    \snippet code/src_corelib_global_qglobal.cpp 38
+
+    An example of a non-POD "primitive" type is QUuid: Even though
+    QUuid has constructors (and therefore isn't POD), every bit
+    pattern still represents a valid object, and memcpy() can be used
+    to create a valid independent copy of a QUuid object.
+
+    Example of a relocatable type:
+
+    \snippet code/src_corelib_global_qglobal.cpp 39
+
+    Qt will try to detect the class of a type using standard C++ type traits;
+    use this macro to tune the behavior.
+    For instance many types would be candidates for Q_RELOCATABLE_TYPE despite
+    not being trivially-copyable.
