    C++ containers such as the ubiquitous std::vector to Python, the

      procedure is not as straightforward as we'd like it to be. Python

      containers do not map easily to C++ containers. Emulating Python

      containers in C++ (see Python Reference Manual, <a href=

      "http://www.python.org/doc/current/ref/sequence-types.html">Emulating

      container types</a>) using Boost Python is non trivial. There are a lot

      of issues to consider before we can map a C++ container to Python
