## Adapted

Fusion provides a couple of adapters for other sequences such as `std::pair`, MPL sequences, and `boost::array`. These adapters are written using Fusion's non-intrusive Extension mechanism. If you wish to use these sequences with fusion, simply include the necessary files and they will be regarded as first-class, fully conforming fusion sequences.

Fusion also provides various schemes to make it easy for the user to adapt various data structures, non-intrusively, as full fledged Fusion sequences.

#### Header

    #include <boost/fusion/adapted.hpp>
    #include <boost/fusion/include/adapted.hpp>

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.
