-[heading Bi-directional adaptation]
-
-Fusion sequences may also be adapted as fully conforming __mpl__ sequences (see
-__intrinsics__). That way, we can have 2-way adaptation to and from __mpl__ and
-Fusion. To make Fusion sequences fully conforming __mpl__ sequences, include:
-
-    #include <boost/fusion/mpl.hpp>
-
-If you want bi-directional adaptation to and from __mpl__ and Fusion, simply
-include:
-
-    #include <boost/fusion/include/mpl.hpp>
-
-The header includes all the necessary headers.
