+modernize-shrink-to-fit
+=======================
+
+
+Replace copy and swap tricks on shrinkable containers with the
+``shrink_to_fit()`` method call.
+
+The ``shrink_to_fit()`` method is more readable and more effective than
+the copy and swap trick to reduce the capacity of a shrinkable container.
+Note that, the ``shrink_to_fit()`` method is only available in C++11 and up.
