Use the /python//numpy target instead of [ numpy.include ] (fixes #361)

Replace <boost/bind.hpp> with <boost/bind/bind.hpp> and use namespace
boost::placeholders when necessary.

+
+[![Join the chat at https://gitter.im/boostorg/python](https://badges.gitter.im/boostorg/python.svg)](https://gitter.im/boostorg/python?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+Welcome to Boost.Python, a C++ library which enables seamless interoperability between C++ and the Python programming language. The library includes support for:
+
+* References and Pointers
+* Globally Registered Type Coercions
+* Automatic Cross-Module Type Conversions
+* Efficient Function Overloading
+* C++ to Python Exception Translation
+* Default Arguments
+* Keyword Arguments
+* Manipulating Python objects in C++
+* Exporting C++ Iterators as Python Iterators
+* Documentation Strings
+
+See the [Boost.Python](http://boostorg.github.io/python) documentation for details.
+
+**Hint :** Check out the [development version](http://boostorg.github.io/python/develop) of the documentation to see work in progress.
+
+# Building ![Test Ubuntu](https://github.com/boostorg/python/workflows/Test%20Ubuntu/badge.svg) ![Test OSX](https://github.com/boostorg/python/workflows/Test%20OSX/badge.svg) ![Test Windows](https://github.com/boostorg/python/workflows/Test%20Windows/badge.svg)
+
+While Boost.Python is part of the Boost C++ Libraries super-project, and thus can be compiled as part of Boost, it can also be compiled and installed stand-alone, i.e. against a pre-installed Boost package.
+

- Introduction
-==============
-
-Python and C++ are in many ways as different as two languages could
-be: while C++ is usually compiled to machine-code, Python is
-interpreted.  Python's dynamic type system is often cited as the
-foundation of its flexibility, while in C++ static typing is the
-cornerstone of its efficiency. C++ has an intricate and difficult
-meta-language to support compile-time polymorphism, while Python is
-a uniform language with convenient runtime polymorphism.
-
-Yet for many programmers, these very differences mean that Python and
-C++ complement one another perfectly.  Performance bottlenecks in
-Python programs can be rewritten in C++ for maximal speed, and
-authors of powerful C++ libraries choose Python as a middleware
-language for its flexible system integration capabilities.
-Furthermore, the surface differences mask some strong similarities:
-
-* 'C'-family control structures (if, while, for...)
-
-* Support for object-orientation, functional programming, and generic
-  programming (these are both *multi-paradigm* programming languages.)
-
-* Comprehensive operator overloading facilities, recognizing the
-  importance of syntactic variability for readability and
-  expressivity.
-
-* High-level concepts such as collections and iterators.
-
-* High-level encapsulation facilities (C++: namespaces, Python: modules)
-  to support the design of re-usable libraries.
-
-* Exception-handling for effective management of error conditions.
-
-* C++ idioms in common use, such as handle/body classes and
-  reference-counted smart pointers mirror Python reference semantics.
-
-Python provides a rich 'C' API for writers of 'C' extension modules.
-Unfortunately, using this API directly for exposing C++ type and
-function interfaces to Python is much more tedious than it should be.
-This is mainly due to the limitations of the 'C' language.  Compared to
-C++ and Python, 'C' has only very rudimentary abstraction facilities.
-Support for exception-handling is completely missing. One important
-undesirable consequence is that 'C' extension module writers are
-required to manually manage Python reference counts. Another unpleasant
-consequence is a very high degree of repetition of similar code in 'C'
-extension modules. Of course highly redundant code does not only cause
-frustration for the module writer, but is also very difficult to
-maintain.
-
-The limitations of the 'C' API have lead to the development of a
-variety of wrapping systems. SWIG_ is probably the most popular package
-for the integration of C/C++ and Python. A more recent development is
-the SIP_ package, which is specifically designed for interfacing Python
-with the Qt_ graphical user interface library. Both SWIG and SIP
-introduce a new specialized language for defining the inter-language
-bindings. Of course being able to use a specialized language has
-advantages, but having to deal with three different languages (Python,
-C/C++ and the interface language) also introduces practical and mental
-difficulties. The CXX_ package demonstrates an interesting alternative.
-It shows that at least some parts of Python's 'C' API can be wrapped
-and presented through a much more user-friendly C++ interface. However,
-unlike SWIG and SIP, CXX does not include support for wrapping C++
-classes as new Python types. CXX is also no longer actively developed.
-
-In some respects Boost.Python combines ideas from SWIG and SIP with
-ideas from CXX. Like SWIG and SIP, Boost.Python is a system for
-wrapping C++ classes as new Python "built-in" types, and C/C++
-functions as Python functions. Like CXX, Boost.Python presents Python's
-'C' API through a C++ interface. Boost.Python goes beyond the scope of
-other systems with the unique support for C++ virtual functions that
-are overrideable in Python, support for organizing extensions as Python
-packages with a central registry for inter-language type conversions,
-and a convenient mechanism for tying into Python's serialization engine
-(pickle). Importantly, all this is achieved without introducing a new
-syntax. Boost.Python leverages the power of C++ meta-programming
-techniques to introspect about the C++ type system, and presents a
-simple, IDL-like C++ interface for exposing C/C++ code in extension
-modules. Boost.Python is a pure C++ library, the inter-language
-bindings are defined in pure C++, and other than a C++ compiler only
-Python itself is required to get started with Boost.Python. Last but
-not least, Boost.Python is an unrestricted open source library. There
-are no strings attached even for commercial applications.

-===========================
- Boost.Python Design Goals 
-===========================
-
-The primary goal of Boost.Python is to allow users to expose C++
-classes and functions to Python using nothing more than a C++
-compiler.  In broad strokes, the user experience should be one of
-directly manipulating C++ objects from Python.
-
-However, it's also important not to translate all interfaces *too*
-literally: the idioms of each language must be respected.  For
-example, though C++ and Python both have an iterator concept, they are
-expressed very differently.  Boost.Python has to be able to bridge the
-interface gap.
-
-It must be possible to insulate Python users from crashes resulting
-from trivial misuses of C++ interfaces, such as accessing
-already-deleted objects.  By the same token the library should
-insulate C++ users from low-level Python 'C' API, replacing
-error-prone 'C' interfaces like manual reference-count management and
-raw ``PyObject`` pointers with more-robust alternatives.
-
-Support for component-based development is crucial, so that C++ types
-exposed in one extension module can be passed to functions exposed in
-another without loss of crucial information like C++ inheritance
-relationships.
-
-Finally, all wrapping must be *non-intrusive*, without modifying or
-even seeing the original C++ source code.  Existing C++ libraries have
-to be wrappable by third parties who only have access to header files
-and binaries.
-
-==========================
- Hello Boost.Python World
-==========================
-
-And now for a preview of Boost.Python, and how it improves on the raw
-facilities offered by Python. Here's a function we might want to
-expose::
-
-    char const* greet(unsigned x)
-    {
-       static char const* const msgs[] = { "hello", "Boost.Python", "world!" };
-
-       if (x > 2) 
-           throw std::range_error("greet: index out of range");
-
-       return msgs[x];
-    }
-
-To wrap this function in standard C++ using the Python 'C' API, we'd
-need something like this::
-
-    extern "C" // all Python interactions use 'C' linkage and calling convention
-    {
-        // Wrapper to handle argument/result conversion and checking
-        PyObject* greet_wrap(PyObject* args, PyObject * keywords)
-        {
-             int x;
-             if (PyArg_ParseTuple(args, "i", &x))    // extract/check arguments
-             {
-                 char const* result = greet(x);      // invoke wrapped function
-                 return PyString_FromString(result); // convert result to Python
-             }
-             return 0;                               // error occurred
-        }
-
-        // Table of wrapped functions to be exposed by the module
-        static PyMethodDef methods[] = {
-            { "greet", greet_wrap, METH_VARARGS, "return one of 3 parts of a greeting" }
-            , { NULL, NULL, 0, NULL } // sentinel
-        };
-
-        // module initialization function
-        DL_EXPORT init_hello()
-        {
-            (void) Py_InitModule("hello", methods); // add the methods to the module
-        }
-    }
-
-Now here's the wrapping code we'd use to expose it with Boost.Python::
-
-    #include <boost/python.hpp>
-    using namespace boost::python;
-    BOOST_PYTHON_MODULE(hello)
-    {
-        def("greet", greet, "return one of 3 parts of a greeting");
-    }
-
-and here it is in action::
-
-    >>> import hello
-    >>> for x in range(3):
-    ...     print hello.greet(x)
-    ...
-    hello
-    Boost.Python
-    world!
-
-Aside from the fact that the 'C' API version is much more verbose than
-the BPL one, it's worth noting that it doesn't handle a few things
-correctly:
-
-* The original function accepts an unsigned integer, and the Python
-  'C' API only gives us a way of extracting signed integers. The
-  Boost.Python version will raise a Python exception if we try to pass
-  a negative number to ``hello.greet``, but the other one will proceed
-  to do whatever the C++ implementation does when converting an
-  negative integer to unsigned (usually wrapping to some very large
-  number), and pass the incorrect translation on to the wrapped
-  function.
-
-* That brings us to the second problem: if the C++ ``greet()``
-  function is called with a number greater than 2, it will throw an
-  exception.  Typically, if a C++ exception propagates across the
-  boundary with code generated by a 'C' compiler, it will cause a
-  crash.  As you can see in the first version, there's no C++
-  scaffolding there to prevent this from happening.  Functions wrapped
-  by Boost.Python automatically include an exception-handling layer
-  which protects Python users by translating unhandled C++ exceptions
-  into a corresponding Python exception.
-
-* A slightly more-subtle limitation is that the argument conversion
-  used in the Python 'C' API case can only get that integer ``x`` in
-  *one way*.  PyArg_ParseTuple can't convert Python ``long`` objects
-  (arbitrary-precision integers) which happen to fit in an ``unsigned
-  int`` but not in a ``signed long``, nor will it ever handle a
-  wrapped C++ class with a user-defined implicit ``operator unsigned
-  int()`` conversion.  The BPL's dynamic type conversion registry
-  allows users to add arbitrary conversion methods.
-
-==================
- Library Overview
-==================
-
-This section outlines some of the library's major features.  Except as
-neccessary to avoid confusion, details of library implementation are
-omitted.
-
--------------------------------------------
- The fundamental type-conversion mechanism
--------------------------------------------
-
-XXX This needs to be rewritten.
-
-Every argument of every wrapped function requires some kind of
-extraction code to convert it from Python to C++.  Likewise, the
-function return value has to be converted from C++ to Python.
-Appropriate Python exceptions must be raised if the conversion fails.
-Argument and return types are part of the function's type, and much of
-this tedium can be relieved if the wrapping system can extract that
-information through  introspection.
-
-Passing a wrapped C++ derived class instance to a C++ function
-accepting a pointer or reference to a base class requires knowledge of
-the inheritance relationship and how to translate the address of a base
-class into that of a derived class.
-
-------------------
- Exposing Classes
-------------------
-
-C++ classes and structs are exposed with a similarly-terse interface.
-Given::
-
-    struct World
-    {
-        void set(std::string msg) { this->msg = msg; }
-        std::string greet() { return msg; }
-        std::string msg;
-    };
-
-The following code will expose it in our extension module::
-    
-    #include <boost/python.hpp>
-    BOOST_PYTHON_MODULE(hello)
-    {
-        class_<World>("World")
-            .def("greet", &World::greet)
-            .def("set", &World::set)
-        ;
-    }
-
-Although this code has a certain pythonic familiarity, people
-sometimes find the syntax bit confusing because it doesn't look like
-most of the C++ code they're used to. All the same, this is just
-standard C++.  Because of their flexible syntax and operator
-overloading, C++ and Python are great for defining domain-specific
-(sub)languages
-(DSLs), and that's what we've done in BPL.  To break it down::
-
-    class_<World>("World")
-
-constructs an unnamed object of type ``class_<World>`` and passes
-``"World"`` to its constructor.  This creates a new-style Python class
-called ``World`` in the extension module, and associates it with the
-C++ type ``World`` in the BPL type conversion registry.  We might have
-also written::
-
-    class_<World> w("World");
-
-but that would've been more verbose, since we'd have to name ``w``
-again to invoke its ``def()`` member function::
-
-        w.def("greet", &World::greet)
-
-There's nothing special about the location of the dot for member
-access in the original example: C++ allows any amount of whitespace on
-either side of a token, and placing the dot at the beginning of each
-line allows us to chain as many successive calls to member functions
-as we like with a uniform syntax.  The other key fact that allows
-chaining is that ``class_<>`` member functions all return a reference
-to ``*this``.
-
-So the example is equivalent to::
-
-    class_<World> w("World");
-    w.def("greet", &World::greet);
-    w.def("set", &World::set);
-
-It's occasionally useful to be able to break down the components of a
-Boost.Python class wrapper in this way, but the rest of this paper
-will tend to stick to the terse syntax.
-
-For completeness, here's the wrapped class in use:
-
->>> import hello
->>> planet = hello.World()
->>> planet.set('howdy')
->>> planet.greet()
-'howdy'
-
-Constructors
-============
-
-Since our ``World`` class is just a plain ``struct``, it has an
-implicit no-argument (nullary) constructor.  Boost.Python exposes the
-nullary constructor by default, which is why we were able to write:
-
->>> planet = hello.World()
-
-However, well-designed classes in any language may require constructor
-arguments in order to establish their invariants.  Unlike Python,
-where ``__init__`` is just a specially-named method, In C++
-constructors cannot be handled like ordinary member functions.  In
-particular, we can't take their address: ``&World::World`` is an
-error.  The library provides a different interface for specifying
-constructors.  Given::
-
-    struct World
-    {
-        World(std::string msg); // added constructor
-        ...
-
-we can modify our wrapping code as follows::
-
-    class_<World>("World", init<std::string>())
-        ...
-
-of course, a C++ class may have additional constructors, and we can
-expose those as well by passing more instances of ``init<...>`` to
-``def()``::
-
-    class_<World>("World", init<std::string>())
-        .def(init<double, double>())
-        ...
-
-Boost.Python allows wrapped functions, member functions, and
-constructors to be overloaded to mirror C++ overloading.
-
-Data Members and Properties
-===========================
-
-Any publicly-accessible data members in a C++ class can be easily
-exposed as either ``readonly`` or ``readwrite`` attributes::
-
-    class_<World>("World", init<std::string>())
-        .def_readonly("msg", &World::msg)
-        ...
-
-and can be used directly in Python:
-
->>> planet = hello.World('howdy')
->>> planet.msg
-'howdy'
-
-This does *not* result in adding attributes to the ``World`` instance
-``__dict__``, which can result in substantial memory savings when
-wrapping large data structures.  In fact, no instance ``__dict__``
-will be created at all unless attributes are explicitly added from
-Python.  BPL owes this capability to the new Python 2.2 type system,
-in particular the descriptor interface and ``property`` type.
-
-In C++, publicly-accessible data members are considered a sign of poor
-design because they break encapsulation, and style guides usually
-dictate the use of "getter" and "setter" functions instead.  In
-Python, however, ``__getattr__``, ``__setattr__``, and since 2.2,
-``property`` mean that attribute access is just one more
-well-encapsulated syntactic tool at the programmer's disposal.  BPL
-bridges this idiomatic gap by making Python ``property`` creation
-directly available to users.  So if ``msg`` were private, we could
-still expose it as attribute in Python as follows::
-
-    class_<World>("World", init<std::string>())
-        .add_property("msg", &World::greet, &World::set)
-        ...
-
-The example above mirrors the familiar usage of properties in Python
-2.2+:
-
->>> class World(object):
-...     __init__(self, msg):
-...         self.__msg = msg
-...     def greet(self):
-...         return self.__msg
-...     def set(self, msg):
-...         self.__msg = msg
-...     msg = property(greet, set)
-
-Operators and Special Functions
-===============================
-
-The ability to write arithmetic operators for user-defined types that
-C++ and Python both allow the definition of has been a major factor in
-the popularity of both languages for scientific computing.  The
-success of packages like NumPy attests to the power of exposing
-operators in extension modules.  In this example we'll wrap a class
-representing a position in a large file::
-
-    class FilePos { /*...*/ };
-
-    // Linear offset
-    FilePos     operator+(FilePos, int);
-    FilePos     operator+(int, FilePos);
-    FilePos     operator-(FilePos, int);
-    
-    // Distance between two FilePos objects
-    int         operator-(FilePos, FilePos);
-
-    // Offset with assignment
-    FilePos&    operator+=(FilePos&, int);
-    FilePos&    operator-=(FilePos&, int);
-
-    // Comparison
-    bool        operator<(FilePos, FilePos);
-
-The wrapping code looks like this::
-
-    class_<FilePos>("FilePos")
-        .def(self + int())     // __add__
-        .def(int() + self)     // __radd__
-        .def(self - int())     // __sub__
-
-        .def(self - self)      // __sub__
-
-        .def(self += int())    // __iadd__
-        .def(self -= int())    // __isub__
-
-        .def(self < self);     // __lt__
-        ;
-
-The magic is performed using a simplified application of "expression
-templates" [VELD1995]_, a technique originally developed by for
-optimization of high-performance matrix algebra expressions.  The
-essence is that instead of performing the computation immediately,
-operators are overloaded to construct a type *representing* the
-computation.  In matrix algebra, dramatic optimizations are often
-available when the structure of an entire expression can be taken into
-account, rather than processing each operation "greedily".
-Boost.Python uses the same technique to build an appropriate Python
-callable object based on an expression involving ``self``, which is
-then added to the class.
-
-Inheritance
-===========
-
-C++ inheritance relationships can be represented to Boost.Python by adding
-an optional ``bases<...>`` argument to the ``class_<...>`` template
-parameter list as follows::
-
-     class_<Derived, bases<Base1,Base2> >("Derived")
-          ...
-
-This has two effects:  
-
-1. When the ``class_<...>`` is created, Python type objects
-   corresponding to ``Base1`` and ``Base2`` are looked up in the BPL
-   registry, and are used as bases for the new Python ``Derived`` type
-   object [#mi]_, so methods exposed for the Python ``Base1`` and
-   ``Base2`` types are automatically members of the ``Derived`` type.
-   Because the registry is global, this works correctly even if
-   ``Derived`` is exposed in a different module from either of its
-   bases.
-
-2. C++ conversions from ``Derived`` to its bases are added to the
-   Boost.Python registry.  Thus wrapped C++ methods expecting (a
-   pointer or reference to) an object of either base type can be
-   called with an object wrapping a ``Derived`` instance.  Wrapped
-   member functions of class ``T`` are treated as though they have an
-   implicit first argument of ``T&``, so these conversions are
-   neccessary to allow the base class methods to be called for derived
-   objects.
-
-Of course it's possible to derive new Python classes from wrapped C++
-class instances.  Because Boost.Python uses the new-style class
-system, that works very much as for the Python built-in types.  There
-is one significant detail in which it differs: the built-in types
-generally establish their invariants in their ``__new__`` function, so
-that derived classes do not need to call ``__init__`` on the base
-class before invoking its methods :
-
->>> class L(list):
-...      def __init__(self):
-...          pass
-...
->>> L().reverse()
->>> 
-
-Because C++ object construction is a one-step operation, C++ instance
-data cannot be constructed until the arguments are available, in the
-``__init__`` function:
-
->>> class D(SomeBPLClass):
-...      def __init__(self):
-...          pass
-...
->>> D().some_bpl_method()
-Traceback (most recent call last):
-  File "<stdin>", line 1, in ?
-TypeError: bad argument type for built-in operation
-
-This happened because Boost.Python couldn't find instance data of type
-``SomeBPLClass`` within the ``D`` instance; ``D``'s ``__init__``
-function masked construction of the base class.  It could be corrected
-by either removing ``D``'s ``__init__`` function or having it call
-``SomeBPLClass.__init__(...)`` explicitly.
-
-Virtual Functions
-=================
-
-Deriving new types in Python from extension classes is not very
-interesting unless they can be used polymorphically from C++.  In
-other words, Python method implementations should appear to override
-the implementation of C++ virtual functions when called *through base
-class pointers/references from C++*.  Since the only way to alter the
-behavior of a virtual function is to override it in a derived class,
-the user must build a special derived class to dispatch a polymorphic
-class' virtual functions::
-
-    //
-    // interface to wrap:
-    //
-    class Base
-    {
-     public:
-        virtual int f(std::string x) { return 42; }
-        virtual ~Base();
-    };
-
-    int calls_f(Base const& b, std::string x) { return b.f(x); }
-
-    //
-    // Wrapping Code
-    //
-
-    // Dispatcher class
-    struct BaseWrap : Base
-    {
-        // Store a pointer to the Python object
-        BaseWrap(PyObject* self_) : self(self_) {}
-        PyObject* self;
-
-        // Default implementation, for when f is not overridden
-        int f_default(std::string x) { return this->Base::f(x); }
-        // Dispatch implementation
-        int f(std::string x) { return call_method<int>(self, "f", x); }
-    };
-
-    ...
-        def("calls_f", calls_f);
-        class_<Base, BaseWrap>("Base")
-            .def("f", &Base::f, &BaseWrap::f_default)
-            ;
-
-Now here's some Python code which demonstrates:
-
->>> class Derived(Base):
-...     def f(self, s):
-...          return len(s)
-...
->>> calls_f(Base(), 'foo')
-42
->>> calls_f(Derived(), 'forty-two')
-9
-
-Things to notice about the dispatcher class:
-
-* The key element which allows overriding in Python is the
-  ``call_method`` invocation, which uses the same global type
-  conversion registry as the C++ function wrapping does to convert its
-  arguments from C++ to Python and its return type from Python to C++.
-
-* Any constructor signatures you wish to wrap must be replicated with
-  an initial ``PyObject*`` argument
-
-* The dispatcher must store this argument so that it can be used to
-  invoke ``call_method``
-
-* The ``f_default`` member function is needed when the function being
-  exposed is not pure virtual; there's no other way ``Base::f`` can be
-  called on an object of type ``BaseWrap``, since it overrides ``f``.
-
-Admittedly, this formula is tedious to repeat, especially on a project
-with many polymorphic classes; that it is neccessary reflects
-limitations in C++'s compile-time reflection capabilities.  Several
-efforts are underway to write front-ends for Boost.Python which can
-generate these dispatchers (and other wrapping code) automatically.
-If these are successful it will mark a move away from wrapping
-everything directly in pure C++ for many of our users.
-
----------------
- Serialization
----------------
-
-*Serialization* is the process of converting objects in memory to a
-form that can be stored on disk or sent over a network connection. The
-serialized object (most often a plain string) can be retrieved and
-converted back to the original object. A good serialization system will
-automatically convert entire object hierarchies. Python's standard
-``pickle`` module is such a system.  It leverages the language's strong
-runtime introspection facilities for serializing practically arbitrary
-user-defined objects. With a few simple and unintrusive provisions this
-powerful machinery can be extended to also work for wrapped C++ objects.
-Here is an example::
-
-    #include <string>
-
-    struct World
-    {
-        World(std::string a_msg) : msg(a_msg) {}
-        std::string greet() const { return msg; }
-        std::string msg;
-    };
-
-    #include <boost/python.hpp>
-    using namespace boost::python;
-
-    struct World_picklers : pickle_suite
-    {
-      static tuple
-      getinitargs(World const& w) { return make_tuple(w.greet()); }
-    };
-
-    BOOST_PYTHON_MODULE(hello)
-    {
-        class_<World>("World", init<std::string>())
-            .def("greet", &World::greet)
-            .def_pickle(World_picklers())
-        ;
-    }
-
-Now let's create a ``World`` object and put it to rest on disk::
-
-    >>> import hello
-    >>> import pickle
-    >>> a_world = hello.World("howdy")
-    >>> pickle.dump(a_world, open("my_world", "w"))
-
-In a potentially *different script* on a potentially *different
-computer* with a potentially *different operating system*::
-
-    >>> import pickle
-    >>> resurrected_world = pickle.load(open("my_world", "r"))
-    >>> resurrected_world.greet()
-    'howdy'
-
-Of course the ``cPickle`` module can also be used for faster
-processing.
-
-Boost.Python's ``pickle_suite`` fully supports the ``pickle`` protocol
-defined in the standard Python documentation. There is a one-to-one
-correspondence between the standard pickling methods (``__getinitargs__``,
-``__getstate__``, ``__setstate__``) and the functions defined by the
-user in the class derived from ``pickle_suite`` (``getinitargs``,
-``getstate``, ``setstate``). The ``class_::def_pickle()`` member function
-is used to establish the Python bindings for all user-defined functions
-simultaneously. Correct signatures for these functions are enforced at
-compile time. Non-sensical combinations of the three pickle functions
-are also rejected at compile time. These measures are designed to
-help the user in avoiding obvious errors.
-
-Enabling serialization of more complex C++ objects requires a little
-more work than is shown in the example above. Fortunately the
-``object`` interface (see next section) greatly helps in keeping the
-code manageable.
-
-------------------
- Object interface
-------------------
-
-Experienced extension module authors will be familiar with the 'C' view
-of Python objects, the ubiquitous ``PyObject*``. Most if not all Python
-'C' API functions involve ``PyObject*`` as arguments or return type.  A
-major complication is the raw reference counting interface presented to
-the 'C' programmer. E.g. some API functions return *new references* and
-others return *borrowed references*. It is up to the extension module
-writer to properly increment and decrement reference counts.  This
-quickly becomes cumbersome and error prone, especially if there are
-multiple execution paths.
-
-Boost.Python provides a type ``object`` which is essentially a high
-level wrapper around ``PyObject*``. ``object`` automates reference
-counting as much as possible. It also provides the facilities for
-converting arbitrary C++ types to Python objects and vice versa.
-This significantly reduces the learning effort for prospective
-extension module writers.
-
-Creating an ``object`` from any other type is extremely simple::
-
-    object o(3);
-
-``object`` has templated interactions with all other types, with
-automatic to-python conversions. It happens so naturally that it's
-easily overlooked.
-
-The ``extract<T>`` class template can be used to convert Python objects
-to C++ types::
-
-    double x = extract<double>(o);
-
-All registered user-defined conversions are automatically accessible
-through the ``object`` interface. With reference to the ``World`` class
-defined in previous examples::
-
-    object as_python_object(World("howdy"));
-    World back_as_c_plus_plus_object = extract<World>(as_python_object);
-
-If a C++ type cannot be converted to a Python object an appropriate
-exception is thrown at runtime.  Similarly, an appropriate exception is
-thrown if a C++ type cannot be extracted from a Python object.
-``extract<T>`` provides facilities for avoiding exceptions if this is
-desired.
-
-The ``object::attr()`` member function is available for accessing
-and manipulating attributes of Python objects. For example::
-
-    object planet(World());
-    planet.attr("set")("howdy");
-
-``planet.attr("set")`` returns a callable ``object``.  ``"howdy"`` is
-converted to a Python string object which is then passed as an argument
-to the ``set`` method.
-
-The ``object`` type is accompanied by a set of derived types
-that mirror the Python built-in types such as ``list``, ``dict``,
-``tuple``, etc. as much as possible. This enables convenient
-manipulation of these high-level types from C++::
-
-    dict d;
-    d["some"] = "thing";
-    d["lucky_number"] = 13;
-    list l = d.keys();
-
-This almost looks and works like regular Python code, but it is pure C++.
-
-=================
- Thinking hybrid
-=================
-
-For many applications runtime performance considerations are very
-important. This is particularly true for most scientific applications.
-Often the performance considerations dictate the use of a compiled
-language for the core algorithms. Traditionally the decision to use a
-particular programming language is an exclusive one. Because of the
-practical and mental difficulties of combining different languages many
-systems are written in just one language. This is quite unfortunate
-because the price payed for runtime performance is typically a
-significant overhead due to static typing. For example, our experience
-shows that developing maintainable C++ code is typically much more
-time-consuming and requires much more hard-earned working experience
-than developing useful Python code. A related observation is that many
-compiled packages are augmented by some type of rudimentary scripting
-layer. These ad hoc solutions clearly show that many times a compiled
-language alone does not get the job done. On the other hand it is also
-clear that a pure Python implementation is too slow for numerically
-intensive production code.
-
-Boost.Python enables us to *think hybrid* when developing new
-applications. Python can be used for rapidly prototyping a
-new application. Python's ease of use and the large pool of standard
-libraries give us a head start on the way to a first working system. If
-necessary, the working procedure can be used to discover the
-rate-limiting algorithms. To maximize performance these can be
-reimplemented in C++, together with the Boost.Python bindings needed to
-tie them back into the existing higher-level procedure.
-
-Of course, this *top-down* approach is less attractive if it is clear
-from the start that many algorithms will eventually have to be
-implemented in a compiled language. Fortunately Boost.Python also
-enables us to pursue a *bottom-up* approach. We have used this approach
-very successfully in the development of a toolbox for scientific
-applications (scitbx) that we will describe elsewhere. The toolbox
-started out mainly as a library of C++ classes with Boost.Python
-bindings, and for a while the growth was mainly concentrated on the C++
-parts. However, as the toolbox is becoming more complete, more and more
-newly added functionality can be implemented in Python. We expect this
-trend to continue, as illustrated qualitatively in this figure:
-
-.. image:: python_cpp_mix.png
-
-This figure shows the ratio of newly added C++ and Python code over
-time as new algorithms are implemented. We expect this ratio to level
-out near 70% Python. The increasing ability to solve new problems
-mostly with the easy-to-use Python language rather than a necessarily
-more arcane statically typed language is the return on the investment
-of learning how to use Boost.Python. The ability to solve some problems
-entirely using only Python will enable a larger group of people to
-participate in the rapid development of new applications.
-
-=============
- Conclusions
-=============
-
-The examples in this paper illustrate that Boost.Python enables
-seamless interoperability between C++ and Python. Importantly, this is
-achieved without introducing a third syntax: the Python/C++ interface
-definitions are written in pure C++. This avoids any problems with
-parsing the C++ code to be interfaced to Python, yet the interface
-definitions are concise and maintainable. Freed from most of the
-development-time penalties of crossing a language boundary, software
-designers can take full advantage of two rich and complimentary
-language environments. In practice it turns out that some things are
-very difficult to do with pure Python/C (e.g. an efficient array
-library with an intuitive interface in the compiled language) and
-others are very difficult to do with pure C++ (e.g. serialization).
-If one has the luxury of being able to design a software system as a
-hybrid system from the ground up there are many new ways of avoiding
-road blocks in one language or the other.
-
-.. I'm not ready to give up on all of this quite yet
-
-.. Perhaps one day we'll have a language with the simplicity and
-   expressive power of Python and the compile-time muscle of C++.  Being
-   able to take advantage of all of these facilities without paying the
-   mental and development-time penalties of crossing a language barrier
-   would bring enormous benefits.  Until then, interoperability tools
-   like Boost.Python can help lower the barrier and make the benefits of
-   both languages more accessible to both communities.
-
-===========
- Footnotes
-===========
-
-.. [#mi] For hard-core new-style class/extension module writers it is
-   worth noting that the normal requirement that all extension classes
-   with data form a layout-compatible single-inheritance chain is
-   lifted for Boost.Python extension classes.  Clearly, either
-   ``Base1`` or ``Base2`` has to occupy a different offset in the
-   ``Derived`` class instance.  This is possible because the wrapped
-   part of BPL extension class instances is never assumed to have a
-   fixed offset within the wrapper.

+=====================
+ Development history
+=====================
+
+The first version of Boost.Python was developed in 2000 by Dave
+Abrahams at Dragon Systems, where he was privileged to have Tim Peters
+as a guide to "The Zen of Python".  One of Dave's jobs was to develop
+a Python-based natural language processing system.  Since it was
+eventually going to be targeting embedded hardware, it was always
+assumed that the compute-intensive core would be rewritten in C++ to
+optimize speed and memory footprint [#proto]_.  The project also wanted to
+test all of its C++ code using Python test scripts [#test]_.  The only
+tool we knew of for binding C++ and Python was SWIG_, and at the time
+its handling of C++ was weak.  It would be false to claim any deep
+insight into the possible advantages of Boost.Python's approach at
+this point.  Dave's interest and expertise in fancy C++ template
+tricks had just reached the point where he could do some real damage,
+and Boost.Python emerged as it did because it filled a need and
+because it seemed like a cool thing to try.
+
+This early version was aimed at many of the same basic goals we've
+described in this paper, differing most-noticeably by having a
+slightly more cumbersome syntax and by lack of special support for
+operator overloading, pickling, and component-based development.
+These last three features were quickly added by Ullrich Koethe and
+Ralf Grosse-Kunstleve [#feature]_, and other enthusiastic contributors arrived
+on the scene to contribute enhancements like support for nested
+modules and static member functions.
+
+By early 2001 development had stabilized and few new features were
+being added, however a disturbing new fact came to light: Ralf had
+begun testing Boost.Python on pre-release versions of a compiler using
+the EDG_ front-end, and the mechanism at the core of Boost.Python
+responsible for handling conversions between Python and C++ types was
+failing to compile.  As it turned out, we had been exploiting a very
+common bug in the implementation of all the C++ compilers we had
+tested.  We knew that as C++ compilers rapidly became more
+standards-compliant, the library would begin failing on more
+platforms.  Unfortunately, because the mechanism was so central to the
+functioning of the library, fixing the problem looked very difficult.
+
+Fortunately, later that year Lawrence Berkeley and later Lawrence
+Livermore National labs contracted with `Boost Consulting`_ for support
+and development of Boost.Python, and there was a new opportunity to
+address fundamental issues and ensure a future for the library.  A
+redesign effort began with the low level type conversion architecture,
+building in standards-compliance and support for component-based
+development (in contrast to version 1 where conversions had to be
+explicitly imported and exported across module boundaries).  A new
+analysis of the relationship between the Python and C++ objects was
+done, resulting in more intuitive handling for C++ lvalues and
+rvalues.
+
+The emergence of a powerful new type system in Python 2.2 made the
+choice of whether to maintain compatibility with Python 1.5.2 easy:
+the opportunity to throw away a great deal of elaborate code for
+emulating classic Python classes alone was too good to pass up.  In
+addition, Python iterators and descriptors provided crucial and
+elegant tools for representing similar C++ constructs.  The
+development of the generalized ``object`` interface allowed us to
+further shield C++ programmers from the dangers and syntactic burdens
+of the Python 'C' API.  A great number of other features including C++
+exception translation, improved support for overloaded functions, and
+most significantly, CallPolicies for handling pointers and
+references, were added during this period.
+
+In October 2002, version 2 of Boost.Python was released.  Development
+since then has concentrated on improved support for C++ runtime
+polymorphism and smart pointers.  Peter Dimov's ingenious
+``boost::shared_ptr`` design in particular has allowed us to give the
+hybrid developer a consistent interface for moving objects back and
+forth across the language barrier without loss of information.  At
+first, we were concerned that the sophistication and complexity of the
+Boost.Python v2 implementation might discourage contributors, but the
+emergence of Pyste_ and several other significant feature
+contributions have laid those fears to rest.  Daily questions on the
+Python C++-sig and a backlog of desired improvements show that the
+library is getting used.  To us, the future looks bright.

+===========
+
+.. [#proto] In retrospect, it seems that "thinking hybrid" from the
+        ground up might have been better for the NLP system: the
+        natural component boundaries defined by the pure python
+        prototype turned out to be inappropriate for getting the
+        desired performance and memory footprint out of the C++ core,
+        which eventually caused some redesign overhead on the Python
+        side when the core was moved to C++.
+
+.. [#test] We also have some reservations about driving all C++
+        testing through a Python interface, unless that's the only way
+        it will be ultimately used.  Any transition across language
+        boundaries with such different object models can inevitably
+        mask bugs.

-    <h2><a name="requirements">Requirements</a></h2>
-    <b>Boost.Python</b> version 2 requires <a href=
-    "http://www.python.org/2.2">Python 2.2</a> <i>or <a href=
-    "http://www.python.org">newer</a></i>. An unsupported archive of
-    Boost.Python version 1, which works with versions of Python since 1.5.2,
-    is available <a href="../build/python_v1.zip">here</a>. 
-
-    <h2><a name="building">Building Boost.Python</a></h2>
-
-    <p>Normally, Boost.Python extension modules must be linked with the
-    <code>boost_python</code> shared library. In special circumstances you
-    may want to link to a static version of the <code>boost_python</code>
-    library, but if multiple Boost.Pythone extension modules are used
-    together, it will prevent sharing of types across extension modules, and
-    consume extra code space. To build <code>boost_python</code>, use <a
-    href="../../../tools/build/index.html">Boost.Build</a> in the usual way
-    from the <code>libs/python/build</code> subdirectory of your boost
-    installation (if you have already built boost from the top level this may
-    have no effect, since the work is already done).</p>
-
-    <h3><a name="configuration">Configuration</a></h3>
-    You may need to configure the following variables to point Boost.Build at
-    your Python installation:

-    <h3><a name="cygwin">Notes for Cygwin GCC Users</a></h3>
-
-    <p>If you are using Cygwin GCC to build extension modules, you must use a
-    Cygwin build of Python. The regular Win32 Python installation that you
-    can download from <a href="http://www.python.org">python.org</a> will not
-    work with your compiler because the dynamic linking conventions are
-    different (you can use <a href="http://www.mingw.org/">MinGW</a> GCC if
-    you want to build extension modules which are compatible with a stock
-    Win32 Python). The Cygwin installer may be able to install an appropriate
-    version of Python, or you can follow the traditional <a href=
-    "http://www.python.org/download/download_source.html">Unix installation
-    process</a> to build Python from source.</p>
-
-    <p>The special build configuration variables listed above as "Cygwin
-    only" make it possible to use a regular Win32 build of bjam to build and
-    test Boost.Python and Boost.Python extensions using Cygwin GCC and
-    targeting a Cygwin build of Python.</p>
-
-    <h3><a name="results">Results</a></h3>
-
-    <p>The build process will create a
-    <code>libs/python/build/bin-stage</code> subdirectory of the boost root
-    (or of <code>$(ALL_LOCATE_TARGET)</code>, if you have set that variable),
-    containing the built libraries. The libraries are actually built to
-    unique directories for each toolset and variant elsewhere in the
-    filesystem, and copied to the <code>bin-stage</code> directory as a
-    convenience, so if you build with multiple toolsets at once, the product
-    of later toolsets will overwrite that of earlier toolsets in
-    <code>bin-stage</code>.</p>
-
-    <h3><a name="testing">Testing</a></h3>
-
-    <p>To build and test Boost.Python, start from the
-    <code>libs/python/test</code> directory and invoke</p>
-
-    <blockquote>
-<pre>
-bjam -sTOOLS=<i><a href=
-"../../../tools/build/index.html#Tools">toolset</a></i> test
-</pre>
-    </blockquote>
-    This will update all of the Boost.Python v1 test and example targets. The
-    tests are relatively quiet by default. To get more-verbose output, you
-    might try 
-
-    <blockquote>
-<pre>
-bjam -sTOOLS=<i><a href=
-"../../../tools/build/index.html#Tools">toolset</a></i> -sPYTHON_TEST_ARGS=-v test
-</pre>
-    </blockquote>
-    which will print each test's Python code with the expected output as it
-    passes. 
-
-    <h2><a name="building_ext">Building your Extension Module</a></h2>
-    Though there are other approaches, the best way to build an extension
-    module using Boost.Python is with Boost.Build. If you have to use another
-    build system, you should use Boost.Build at least once with the
-    "<code><b>-n</b></code>" option so you can see the command-lines it uses,
-    and replicate them. You are likely to run into compilation or linking
-    problems otherwise. 
-
-    <h3><a name="easy">The Easy Way</a></h3>
-    Until Boost.Build v2 is released, cross-project build dependencies are
-    not supported, so it works most smoothly if you add a new subproject to
-    your boost installation. The <code>libs/python/example</code>
-    subdirectory of your boost installation contains a minimal example (along
-    with many extra sources). To copy the example subproject: 
-
-    <ol>
-      <li>Create a new subdirectory in, <code>libs/python</code>, say
-      <code>libs/python/my_project</code>.</li>
-
-      <li>Copy <code><a href=
-      "../example/Jamfile">libs/python/example/Jamfile</a></code> to your new
-      directory.</li>
-
-      <li>Edit the Jamfile as appropriate for your project. You'll want to
-      change the "<code>subproject</code>" rule invocation at the top, and
-      the names of some of the source files and/or targets.</li>
-    </ol>
-    The instructions <a href="#testing">above</a> for testing Boost.Python
-    apply equally to your new extension modules in this subproject. 
-
-    <h3><a name="outside">Building your module outside the Boost project
-    tree</a></h3>
-    If you can't (or don't wish to) modify your boost installation, the
-    alternative is to create your own Boost.Build project. A similar example
-    you can use as a starting point is available in <code><a href=
-    "../example/project.zip">this archive</a></code>. You'll need to edit the
-    Jamfile and Jamrules files, depending on the relative location of your
-    Boost installation and the new project. Note that automatic testing of
-    extension modules is not available in this configuration. 
-
-    <h2><a name="variants">Build Variants</a></h2>
-    Three <a href=
-    "../../../tools/build/build_system.htm#variants">variant</a>
-    configurations of all python-related targets are supported, and can be
-    selected by setting the <code><a href=
-    "../../../tools/build/build_system.htm#user_globals">BUILD</a></code>
-    variable: 
-
-    <ul>
-      <li><code>release</code> (optimization, <tt>-DNDEBUG</tt>)</li>
-
-      <li><code>debug</code> (no optimization <tt>-D_DEBUG</tt>)</li>
-
-      <li><code>debug-python</code> (no optimization, <tt>-D_DEBUG
-      -DBOOST_DEBUG_PYTHON</tt>)</li>
-    </ul>
-
-    <p>The first two variants of the <code>boost_python</code> library are
-    built by default, and are compatible with the default Python
-    distribution. The <code>debug-python</code> variant corresponds to a
-    specially-built debugging version of Python. On Unix platforms, this
-    python is built by adding <code>--with-pydebug</code> when configuring
-    the Python build. On Windows, the debugging version of Python is
-    generated by the "Win32 Debug" target of the <code>PCBuild.dsw</code>
-    Visual C++ 6.0 project in the <code>PCBuild</code> subdirectory of your
-    Python distribution. Extension modules built with Python debugging
-    enabled are <b>not link-compatible</b> with a non-debug build of Python.
-    Since few people actually have a debug build of Python (it doesn't come
-    with the standard distribution), the normal <code>debug</code> variant
-    builds modules which are compatible with ordinary Python.</p>
-
-    <p>On many windows compilers, when extension modules are built with
-    <tt>-D_DEBUG</tt>, Python defaults to <i>force</i> linking with a special
-    debugging version of the Python DLL. Since this debug DLL isn't supplied
-    with the default Python installation for Windows, Boost.Python uses
-    <tt><a href=
-    "../../../boost/python/detail/wrap_python.hpp">boost/python/detail/wrap_python.hpp</a></tt>
-    to temporarily undefine <tt>_DEBUG</tt> when <tt>Python.h</tt> is
-    <tt>#include</tt>d - unless <code>BOOST_DEBUG_PYTHON</code> is
-    defined.</p>
-
-    <p>If you want the extra runtime checks available with the debugging
-    version of the library, <tt>#define BOOST_DEBUG_PYTHON</tt> to re-enable
-    python debuggin, and link with the <code>debug-python</code> variant of
-    <tt>boost_python</tt>.</p>
-
-    <p>If you do not <tt>#define BOOST_DEBUG_PYTHON</tt>, be sure that any
-    source files in your extension module <tt>#include&nbsp;&lt;<a href=
-    "../../../boost/python/detail/wrap_python.hpp">boost/python/detail/wrap_python.hpp</a>&gt;</tt>
-    instead of the usual <tt>Python.h</tt>, or you will have link
-    incompatibilities.<br>
-    </p>
-
-    <h2><a name="VisualStudio">Building Using the Microsoft Visual Studio
-    IDE</a></h2>
-
-    <p>For the those of you who feel more comfortable in the IDE world, a
-    workspace and project file have been included in the <a href=
-    "../build/VisualStudio">libs/python/build/VisualStudio</a> subdirectory.
-    It builds release and debug versions of the Boost.Python libraries and
-    places them and the same directory as Jamfile build does, though the
-    intermediate object files are placed in a different directory. The files
-    have been created using Microsoft Visual C++ version 6, but they should
-    work for later versions as well. You will need to tell the IDE where to
-    find the Python <code>Include/</code> and <code>Libs/</code> directories.
-    Under <b>Tools&gt;Options&gt;Directories</b>, add an entry for the Python
-    include dir (i.e. <code>c:/Python22/Include</code>), and one for the Lib
-    (i.e. <code>c:/Python/Libs</code>. Make sure it is <code>Libs</code> with
-    an "<code>s</code>" and not just <code>Lib</code>).</p>
-
-    <h3>Using the IDE for you own projects</h3>
-
-    <p>Building your own projects using the IDE is slightly more complicated.
-    Firstly, you need to make sure that the project you create as the right
-    kind. It should be a "Win32 Dynamic-Link Library". The default one that
-    Visual Studio 6 creates needs some modifications: turn on RTTI, and
-    change the debug and release builds to use the respective debug and
-    release Multithreaded DLL versions. You should probably turn off
-    incremental linking too -- I believe it a bit flaky. If you do this, then
-    change the "Debug Info" to "Program Database" to get rid of the Edit and
-    Continue warning.</p>
-
-    <p>You'll need to add the Boost root directory under
-    <b>Tools&gt;Options&gt;Directories</b> to get your code compiling. To
-    make it link, add the above <code>boost_python.dsp</code> file to your
-    workspace, and make your project depend upon it (under
-    <b>Project&gt;Dependencies</b>). You should be able to build now.</p>
-
-    <p>Lastly, go to the <b>Project Settings&gt;Debug</b> Page and add the
-    <code>Python.exe</code> as the executable for the project. Set a startup
-    directory, and make sure that your current project's output dll, the
-    <code>boost_python.dll</code> and the <code>python22.dll</code> are on
-    the current <code>PATH</code>. If you have a python script that tests
-    your dll, then add it in the "Program Arguments". Now, if all went well,
-    you should be able to hit the Run (F5) button, and debug your code.</p>

+[section Requirements]
+
+Boost.Python requires [@http://www.python.org/2.2 Python 2.2]
+[footnote Note that although we tested earlier versions of Boost.Python
+ with Python 2.2, and we don't *think* we've done anything to break
+ compatibility, this release of Boost.Python may not have been tested
+ with versions of Python earlier than 2.4, so we're not 100% sure that
+ python 2.2 and 2.3 are supported.] *or* [@http://www.python.org newer].  
+
+[endsect]
+[section Background]
+
+There are two basic models for combining C++ and Python:
+
+* [@http://www.python.org/doc/current/ext/intro.html extending],
+  in which the end-user launches the Python interpreter
+  executable and imports Python “extension modules” written in C++.
+  Think of taking a library written in C++ and giving it a Python
+  interface so Python programmers can use it.  From Python, these
+  modules look just like regular Python modules.
+
+* [@http://www.python.org/doc/current/ext/embedding.html embedding],
+  in which the end-user launches a program written
+  in C++ that in turn invokes the Python interpreter as a library
+  subroutine.  Think of adding scriptability to an existing
+  application.
+
+The key distinction between extending and embedding is the location
+of the C++ `main()` function: in the Python interpreter executable,
+or in some other program, respectively.  Note that even when
+embedding Python in another program, [@http://www.python.org/doc/current/ext/extending-with-embedding.html extension modules are often
+the best way to make C/C++ functionality accessible to Python
+code], so the use of extension modules is really at the heart of
+both models.
+
+Except in rare cases, extension modules are built as
+dynamically-loaded libraries with a single entry point, which means
+you can change them without rebuilding either the other extension
+modules or the executable containing `main()`.
+
+[endsect]
+[section No-Install Quickstart]
+
+There is no need to “install Boost” in order to get started using
+Boost.Python.  These instructions use _bb_ projects,
+which will build those binaries as soon as they're needed.  Your
+first tests may take a little longer while you wait for
+Boost.Python to build, but doing things this way will save you from
+worrying about build intricacies like which library binaries to use
+for a specific compiler configuration and figuring out the right
+compiler options to use yourself.
+
+[note Of course it's possible to use other build systems to
+   build Boost.Python and its extensions, but they are not
+   officially supported by Boost.  Moreover *99% of all “I can't
+   build Boost.Python” problems come from trying to use another
+   build system* without first following these instructions.
+
+   If you want to use another system anyway, we suggest that you
+   follow these instructions, and then invoke `bjam` with the
+
+   `-a -o`\ /filename/ 
+
+   options to dump the build commands it executes to a file, so
+   you can see what your alternate build system needs to do.]
+
+[section Basic Procedure]
+
+1. Get Boost; see sections 1 and 2 of the _gsg_.
+
+2. Get the `bjam` build driver.  See section 5 of the _gsg_.
+
+3. cd into the `example/quickstart/` directory of your
+   Boost.Python installation, which contains a small example project.
+
+4. Invoke `bjam`.  Replace the “\ `stage`\ “ argument from the
+   example invocation from section 5 of the _gsg_ with “\ `test`\ ,“ to
+   build all the test targets.  Also add the argument “\ `--verbose-test`\ ”
+   to see the output generated by the tests when they are run.
+   On Windows, your `bjam` invocation might look something like:
+   ``
+     C:\\...\\quickstart> bjam toolset=msvc --verbose-test test
+   ``
+   and on Unix variants, perhaps,
+   ``
+     .../quickstart$ bjam toolset=gcc --verbose-test test
+   ``
+
+[note For the sake of concision, the rest of this guide will use
+   unix-style forward slashes in pathnames instead of the
+   backslashes with which Windows users may be more familiar.  The forward
+   slashes should work everywhere except in
+   [@http://www.boost.org/more/getting_started/windows.html#command-prompt
+   Command Prompt] windows, where you should use backslashes.]
+
+If you followed this procedure successfully, you will have built an
+extension module called `extending` and tested it by running a
+Python script called `test_extending.py`.  You will also have
+built and run a simple application called `embedding` that embeds
+python.
+
+[endsect]
+[section In Case of Trouble]
+
+If you're seeing lots of compiler and/or linker error messages,
+it's probably because Boost.Build is having trouble finding your
+Python installation.  You might want to pass the
+`--debug-configuration` option to `bjam` the first few times
+you invoke it, to make sure that Boost.Build is correctly locating
+all the parts of your Python installation.  If it isn't, consider
+[link building.configuring_boost_build Configuring Boost.Build]
+as detailed below.
+
+If you're still having trouble, Someone on one of the following
+mailing lists may be able to help:
+
+* The _bb_list_ for issues related to Boost.Build
+* The _bp_list_ for issues specifically related to Boost.Python
+
+[endsect]
+[section In Case Everything Seemed to Work]
+
+Rejoice!  If you're new to Boost.Python, at this point it might be
+a good idea to ignore build issues for a while and concentrate on
+learning the library by going through the _tutorial_ and perhaps
+some of the _reference_, trying out what you've
+learned about the API by modifying the quickstart project.
+
+[endsect]
+[section Modifying the Example Project]
+
+If you're content to keep your extension module forever in one
+source file called `extending.cpp`, inside your Boost.Python
+distribution, and import it forever as `extending`, then you can
+stop here.  However, it's likely that you will want to make a few
+changes.  There are a few things you can do without having to learn
+_bb_ in depth.
+
+The project you just built is specified in two files in the current
+directory: `boost-build.jam`, which tells `bjam` where it can
+find the interpreted code of the Boost build system, and
+`Jamroot`, which describes the targets you just built.  These
+files are heavily commented, so they should be easy to modify.
+Take care, however, to preserve whitespace.  Punctuation such as
+`;` will not be recognized as intended by `bjam` if it is not
+surrounded by whitespace.
+
+[section Relocate the Project]
+
+You'll probably want to copy this project elsewhere so you can
+change it without modifying your Boost distribution.  To do that,
+simply
+
+a. copy the entire `example/quickstart/` directory
+   into a new directory.
+
+b. In the new copies of `boost-build.jam` and `Jamroot`, locate
+   the relative path near the top of the file that is clearly
+   marked by a comment, and edit that path so that it refers to the
+   same directory your Boost distribution as it referred to when
+   the file was in its original location in the
+   `example/quickstart/` directory.
+
+For example, if you moved the project from
+`/home/dave/boost_1_34_0/libs/python/example/quickstart` to
+`/home/dave/my-project`, you could change the first path in
+`boost-build.jam` from
+``
+  ../../../../tools/build/src
+``
+to
+``
+  /home/dave/boost_1_34_0/tools/build/src
+``
+and change the first path in `Jamroot` from
+``
+  ../../../..
+``
+to
+``
+  /home/dave/boost_1_34_0
+``
+
+[endsect]
+[section Add New or Change Names of Existing Source Files]
+
+The names of additional source files involved in building your
+extension module or embedding application can be listed in
+`Jamroot` right alongside `extending.cpp` or `embedding.cpp`
+respectively.  Just be sure to leave whitespace around each
+filename:
+``
+  … file1.cpp file2.cpp file3.cpp …
+``
+Naturally, if you want to change the name of a source file you can
+tell Boost.Build about it by editing the name in `Jamroot`.
+
+[endsect]
+[section Change the Name of your Extension Module]
+
+The name of the extension module is determined by two things:
+
+# the name in `Jamroot` immediately following `python-extension`, and 
+# the name passed to `BOOST_PYTHON_MODULE` in `extending.cpp`.
+
+To change the name of the extension module from `extending` to
+`hello`, you'd edit `Jamroot`, changing
+``
+  python-extension extending : extending.cpp ;
+``
+to
+``
+  python-extension hello : extending.cpp ;
+``
+and you'd edit extending.cpp, changing
+
+``
+  BOOST_PYTHON_MODULE(extending)
+``
+to
+``
+  BOOST_PYTHON_MODULE(hello)
+``
+[endsect]
+[endsect]
+[endsect]
+[section Installing Boost.Python on your System]
+
+Since Boost.Python is a separately-compiled (as opposed to
+`header-only`) library, its user relies on the services of a
+Boost.Python library binary.  
+
+If you need a regular installation of the Boost.Python library
+binaries on your system, the _gsg_ will
+walk you through the steps of creating one.  If building binaries
+from source, you might want to supply the `--with-python`
+argument to `bjam` (or the `--with-libraries=python` argument
+to `configure`), so only the Boost.Python binary will be built,
+rather than all the Boost binaries.
+
+[endsect]
+[section Configuring Boost.Build]
+
+As described in the [@http://www.boost.org/build/doc/html/bbv2/overview/configuration.html Boost.Build Reference Manual], a file called
+`user-config.jam` in your home directory is used to
+specify the tools and libraries available to the build system. You
+may need to create or edit `user-config.jam` to tell Boost.Build
+how to invoke Python, `#include` its headers, and link with its
+libraries.
+
+[note If you are using a unix-variant OS and you ran Boost's
+   `configure` script, it may have generated a
+   `user-config.jam` for you. [footnote `configure` overwrites the existing
+   `user-config.jam` in your home directory (if any) after making a backup of
+   the old version.] If your `configure`\ /\ `make` sequence was successful and
+   Boost.Python binaries were built, your `user-config.jam` file is probably already
+   correct.]
+
+If you have one fairly “standard” python installation for your
+platform, you might not need to do anything special to describe it.  If
+you haven't configured python in `user-config.jam` (and you don't
+specify `--without-python` on the Boost.Build command line),
+Boost.Build will automatically execute the equivalent of
+
+``
+  import toolset : using ; 
+  using python ;
+``
+which automatically looks for Python in the most likely places.
+However, that only happens when using the Boost.Python project file
+(e.g. when referred to by another project as in the quickstart
+method).  If instead you are linking against separately-compiled
+Boost.Python binaries, you should set up a `user-config.jam` file
+with at least the minimal incantation above.
+
+[section Python Configuration Parameters]
+
+If you have several versions of Python installed, or Python is
+installed in an unusual way, you may want to supply any or all of
+the following optional parameters to `using python`.
+
+[variablelist
+ [[version]
+
+  [the version of Python to use.  Should be in Major.Minor
+  format, for example, `2.3`.  Do not include the subminor
+  version (i.e. *not* `2.5.1`).  If you have multiple Python
+  versions installed, the version will usually be the only
+  configuration argument required.]]
+
+ [[cmd-or-prefix]
+
+  [preferably, a command that invokes a Python interpreter.
+  Alternatively, the installation prefix for Python libraries and
+  header files.  Only use the alternative formulation if there is
+  no appropriate Python executable available.]]
+
+ [[*includes*]
+
+  [the `#include` paths for Python headers.  Normally the correct
+  path(s) will be automatically deduced from `version` and/or
+  `cmd-or-prefix`.]]
+
+ [[*libraries*]
+
+  [the path to Python library binaries.  On MacOS/Darwin,
+  you can also pass the path of the Python framework.  Normally the
+  correct path(s) will be automatically deduced from `version`
+  and/or `cmd-or-prefix`.]]
+
+ [[*condition*]
+
+  [if specified, should be a set of Boost.Build
+  properties that are matched against the build configuration when
+  Boost.Build selects a Python configuration to use.  See examples
+  below for details.]]
+
+ [[*extension-suffix*]
+
+  [A string to append to the name of extension
+  modules before the true filename extension.  You almost certainly
+  don't need to use this.  Usually this suffix is only used when
+  targeting a Windows debug build of Python, and will be set
+  automatically for you based on the value of the
+  [link building.python_debugging_builds <python-debugging>] feature.
+  However, at least one Linux distribution (Ubuntu Feisty Fawn) has
+  a specially configured [@https://wiki.ubuntu.com/PyDbgBuilds <python-dbg>]
+  package that claims to use such a suffix.]]
+  ]
+
+[endsect]
+[section Examples]
+
+Note that in the examples below, case and *especially whitespace* are
+significant.
+
+* If you have both python 2.5 and python 2.4 installed,
+  `user-config.jam` might contain
+  
+  ``
+    using python : 2.5 ;  # Make both versions of Python available 
+    using python : 2.4 ;  # To build with python 2.4, add python=2.4 
+                          # to your command line.
+  ``
+  The first version configured (2.5) becomes the default.  To build
+  against python 2.4, add `python=2.4` to the `bjam` command line.
+
+* If you have python installed in an unusual location, you might
+  supply the path to the interpreter in the `cmd-or-prefix`
+  parameter:
+
+  ``
+    using python : : /usr/local/python-2.6-beta/bin/python ;
+  ``
+
+* If you have a separate build of Python for use with a particular
+  toolset, you might supply that toolset in the `condition`
+  parameter:
+
+  ``
+    using python ;  # use for most toolsets
+    
+    # Use with Intel C++ toolset
+    using python 
+         : # version
+         : c:\\Devel\\Python-2.5-IntelBuild\\PCBuild\\python # cmd-or-prefix
+         : # includes
+         : # libraries
+         : <toolset>intel # condition
+         ;
+  ``
+
+* If you have downloaded the Python sources and built both the
+  normal and the [link building.python_debugging_builds "python debugging"]
+  builds from source on Windows, you might see:
+
+  ``
+    using python : 2.5 : C:\\src\\Python-2.5\\PCBuild\\python ;
+    using python : 2.5 : C:\\src\\Python-2.5\\PCBuild\\python_d
+      : # includes
+      : # libs
+      : <python-debugging>on ;
+  ``
+* You can set up your user-config.jam so a bjam built under Windows 
+  can build/test both Windows and Cygwin_ python extensions.  Just pass
+  `<target-os>cygwin` in the `condition` parameter
+  for the cygwin python installation:
+
+  ``
+    # windows installation
+    using python ;
+
+    # cygwin installation
+    using python : : c:\\cygwin\\bin\\python2.5 : : : <target-os>cygwin ;
+  ``
+  when you put target-os=cygwin in your build request, it should build
+  with the cygwin version of python: [#flavor]_
+
+  ``
+    bjam target-os=cygwin toolset=gcc 
+  ``
+  This is supposed to work the other way, too (targeting windows
+  python with a [@http://cygwin.com Cygwin] bjam) but it seems as though the support in
+  Boost.Build's toolsets for building that way is broken at the
+  time of this writing.
+
+* Note that because of [@http://zigzag.cs.msu.su/boost.build/wiki/AlternativeSelection
+  the way Boost.Build currently selects target alternatives], you might have be very
+  explicit in your build requests.  For example, given:
+
+  ``
+    using python : 2.5 ; # a regular windows build
+    using python : 2.4 : : : : <target-os>cygwin ;
+  ``
+  building with
+  ``
+    bjam target-os=cygwin
+  ``
+
+  will yield an error.  Instead, you'll need to write
+
+  ``
+    bjam target-os=cygwin/python=2.4
+  ``
+
+[endsect]
+[endsect]
+[section Choosing a Boost.Python Library Binary]
+
+If—instead of letting Boost.Build construct and link with the right
+libraries automatically—you choose to use a pre-built Boost.Python
+library, you'll need to think about which one to link with.  The
+Boost.Python binary comes in both static and dynamic flavors.  Take
+care to choose the right flavor for your application. [footnote
+Information about how to identify the static and dynamic builds of Boost.Python on
+[@http://boost.org/more/getting_started/windows.html#library-naming Windows] /
+[@http://boost.org/more/getting_started/unix-variants.html#library-naming Unix variants]]
+
+[section The Dynamic Binary]
+
+The dynamic library is the safest and most-versatile choice:
+
+* A single copy of the library code is used by all extension
+  modules built with a given toolset. [footnote Because of the way most \*nix platforms
+  share symbols among dynamically-loaded objects, I'm not certain
+  that extension modules built with different compiler toolsets
+  will always use different copies of the Boost.Python library
+  when loaded into the same Python instance.  Not using different
+  libraries could be a good thing if the compilers have compatible
+  ABIs, because extension modules built with the two libraries
+  would be interoperable.  Otherwise, it could spell disaster,
+  since an extension module and the Boost.Python library would
+  have different ideas of such things as class layout. I would
+  appreciate someone doing the experiment to find out what
+  happens.]
+
+* The library contains a type conversion registry.  Because one
+  registry is shared among all extension modules, instances of a
+  class exposed to Python in one dynamically-loaded extension
+  module can be passed to functions exposed in another such module.
+
+[endsect]
+[section The Static Binary]
+
+It might be appropriate to use the static Boost.Python library in
+any of the following cases:
+
+* You are _extending_ python and the types exposed in your
+  dynamically-loaded extension module don't need to be used by any
+  other Boost.Python extension modules, and you don't care if the
+  core library code is duplicated among them.
+
+* You are _embedding_ python in your application and either:
+
+  * You are targeting a Unix variant OS other than MacOS or AIX,
+    where the dynamically-loaded extension modules can “see” the
+    Boost.Python library symbols that are part of the executable.
+
+  * Or, you have statically linked some Boost.Python extension
+    modules into your application and you don't care if any
+    dynamically-loaded Boost.Python extension modules are able to
+    use the types exposed by your statically-linked extension
+    modules (and vice-versa).
+
+[endsect]
+[endsect]
+[section `#include` Issues]
+
+1. If you should ever have occasion to `#include "python.h"`
+   directly in a translation unit of a program using Boost.Python,
+   use `#include "boost/python/detail/wrap_python.hpp"` instead.
+   It handles several issues necessary for use with Boost.Python,
+   one of which is mentioned in the next section.
+
+2. Be sure not to `#include` any system headers before
+   `wrap_python.hpp`.  This restriction is actually imposed by
+   Python, or more properly, by Python's interaction with your
+   operating system.  See
+   [@http://docs.python.org/ext/simpleExample.html] for details.
+
+[endsect]
+[section Python Debugging Builds]
+
+Python can be built in a special “python debugging” configuration
+that adds extra checks and instrumentation that can be very useful
+for developers of extension modules.  The data structures used by
+the debugging configuration contain additional members, so *a
+Python executable built with python debugging enabled cannot be
+used with an extension module or library compiled without it, and
+vice-versa.*
+
+Since pre-built “python debugging” versions of the Python
+executable and libraries are not supplied with most distributions
+of Python, [footnote On Unix and similar platforms, a debugging python and associated libraries are built by adding --with-pydebug when configuring the Python build. On Windows, the debugging version of Python is generated by the "Win32 Debug" target of the Visual Studio project in the PCBuild subdirectory of a full Python source code distribution.] and we didn't want to force our users
+to build them, Boost.Build does not automatically enable python
+debugging in its `debug` build variant (which is the default).
+Instead there is a special build property called
+`python-debugging` that, when used as a build property, will
+define the right preprocessor symbols and select the right
+libraries to link with.
+
+On unix-variant platforms, the debugging versions of Python's data
+structures will only be used if the symbol `Py_DEBUG` is defined.
+On many windows compilers, when extension modules are built with
+the preprocessor symbol `_DEBUG`, Python defaults to force
+linking with a special debugging version of the Python DLL.  Since
+that symbol is very commonly used even when Python is not present,
+Boost.Python temporarily undefines `_DEBUG` when `Python.h`
+is #included from `boost/python/detail/wrap_python.hpp` - unless
+`BOOST_DEBUG_PYTHON` is defined.  The upshot is that if you want
+“python debugging”and you aren't using Boost.Build, you should make
+sure `BOOST_DEBUG_PYTHON` is defined, or python debugging will be
+suppressed.
+
+[endsect]
+[section Testing Boost.Python]
+
+To run the full test suite for Boost.Python, invoke `bjam` in the
+`test` subdirectory of your Boost.Python distribution.
+
+[endsect]
+[section Notes for MinGW (and Cygwin with -mno-cygwin) GCC Users]
+
+If you are using a version of Python prior to 2.4.1 with a MinGW
+prior to 3.0.0 (with binutils-2.13.90-20030111-1), you will need to
+create a MinGW-compatible version of the Python library; the one
+shipped with Python will only work with a Microsoft-compatible
+linker. Follow the instructions in the “Non-Microsoft” section of
+the “Building Extensions: Tips And Tricks” chapter in
+[@https://docs.python.org/2/install/index.html Installing Python Modules]
+to create `libpythonXX.a`, where `XX` corresponds to the major and minor
+version numbers of your Python installation.

+[section Configuration]
+
+[section Introduction]
+[*Boost.Python] uses several configuration macros in `<boost/config.hpp>`, as well as configuration macros meant to be supplied by the application. These macros are documented here.
+
+[endsect]
+[section Application Defined Macros]
+
+These are the macros that may be defined by an application using Boost.Python. Note that if you extend a strict interpretation of the C++ standard to cover dynamic libraries, using different values of these macros when compiling different libraries (including extension modules and the Boost.Python library itself) is a violation of the [link odr ODR]. However, we know of no C++ implementations on which this particular violation is detectable or causes any problems.
+
+[table
+ [[Macro][Default][Meaning]]
+ [[BOOST_PYTHON_MAX_ARITY]
+  [15]
+  [The maximum arity of any function, member function,
+   or constructor to be wrapped, invocation of a
+   Boost.Python function wich is specified as taking
+   arguments x1, x2,...Xn. This includes, in particular,
+   callback mechanisms such as object::operator()(...) or call_method<R>(... ).]]
+ [[BOOST_PYTHON_MAX_BASES][10]
+  [The maximum number of template arguments to the
+   `bases<...>` class template, which is used to specify
+   the bases of a wrapped C++ class..]]
+ [[BOOST_PYTHON_STATIC_MODULE]
+  [ /not defined/ ]
+  [If defined, prevents your module initialization
+   function from being treated as an exported symbol
+   on platforms which support that distinction in-code]]
+ [[BOOST_PYTHON_ENABLE_CDECL]
+  [ /not defined/ ]
+  [If defined, allows functions using the `__cdecl`
+   calling convention to be wrapped.]]
+ [[BOOST_PYTHON_ENABLE_STDCALL]
+  [ /not defined/ ]
+  [If defined, allows functions using the `__stdcall`
+   calling convention to be wrapped.]]
+ [[BOOST_PYTHON_ENABLE_FASTCALL]
+  [ /not defined/ ]
+  [If defined, allows functions using the `__fastcall`
+   calling convention to be wrapped.]]
+]
+[endsect]
+[section Library Defined Defined Macros]
+These macros are defined by *Boost.Python* and are implementation details of interest only to implementors and those porting to new platforms.
+[table
+ [[Macro][Default][Meaning]]
+ [[BOOST_PYTHON_TYPE_ID_NAME][ /not defined/ ]
+  [If defined, this indicates that the type_info comparison across
+   shared library boundaries does not work on this platform.
+   In other words, if shared-lib-1 passes `typeid(T)` to a function
+   in shared-lib-2 which compares it to `typeid(T)`, that comparison
+   may return `false`. If this macro is #defined, Boost.Python uses
+   and compares `typeid(T).name()` instead of using and comparing
+   the `std::type_info` objects directly.]]
+ [[BOOST_PYTHON_NO_PY_SIGNATURES][ /not defined/ ]
+  [If defined for a module no pythonic signatures are generated for
+   the docstrings of the module functions, and no python type is
+   associated with any of the converters registered by the module.
+   This also reduces the binary size of the module by about 14%
+   (gcc compiled).
+   If defined for the boost_python runtime library, the default for
+   the `docstring_options.enable_py_signatures()` is set to `false`.]]
+ [[BOOST_PYTHON_SUPPORTS_PY_SIGNATURES]
+  [ /defined/ if `BOOST_PYTHON_NO_PY_SIGNATURES` is /undefined/ ]
+  [This macro is defined to enable a smooth transition from older
+   Boost.Python versions which do not support pythonic signatures.
+   For example usage see here.]]
+ [[BOOST_PYTHON_PY_SIGNATURES_PROPER_INIT_SELF_TYPE][ /not defined/ ]
+  [If defined the python type of `__init__` method "self" parameters
+   is properly generated, otherwise object is used. It is undefined by
+   default because it increases the binary size of the module by about
+   14% (gcc compiled).]]

+[section How can I wrap a function which takes a function pointer as an argument?]
+
+If what you're trying to do is something like this:
+``
+  typedef boost::function<void (string s) > funcptr;
+
+  void foo(funcptr fp)
+  {
+    fp("hello,world!");
+  }
+
+  BOOST_PYTHON_MODULE(test)
+  {
+    def("foo",foo);
+  }
+``
+
+And then:
+
+``
+>>> def hello(s):
+...    print s
+...
+>>> foo(hello)
+hello, world!
+``
+The short answer is: "you can't".  This is not a
+Boost.Python limitation so much as a limitation of C++.  The
+problem is that a Python function is actually data, and the only
+way of associating data with a C++ function pointer is to store it
+in a static variable of the function.  The problem with that is
+that you can only associate one piece of data with every C++
+function, and we have no way of compiling a new C++ function
+on-the-fly for every Python function you decide to pass
+to `foo`.  In other words, this could work if the C++
+function is always going to invoke the /same/ Python
+function, but you probably don't want that.
+
+If you have the luxury of changing the C++ code you're
+wrapping, pass it an `object` instead and call that;
+the overloaded function call operator will invoke the Python
+function you pass it behind the `object`.
+
+[endsect]
+[section I'm getting the "attempt to return dangling reference" error.
+ What am I doing wrong?]
+
+That exception is protecting you from causing a nasty crash. It usually
+happens in response to some code like this:
+``
+  period const &get_floating_frequency() const
+  {
+    return boost::python::call_method<period const &>( 
+      m_self,"get_floating_frequency");
+  }
+``
+And you get:
+``
+  ReferenceError: Attempt to return dangling reference to object of type:
+  class period
+``
+
+In this case, the Python method invoked by `call_method`
+constructs a new Python object. You're trying to return a reference to a
+C++ object (an instance of `class period`) contained within
+and owned by that Python object. Because the called method handed back a
+brand new object, the only reference to it is held for the duration of
+`get_floating_frequency()` above. When the function returns,
+the Python object will be destroyed, destroying the instance of
+`class period`, and leaving the returned reference dangling.
+That's already undefined behavior, and if you try to do anything with
+that reference you're likely to cause a crash. Boost.Python detects this
+situation at runtime and helpfully throws an exception instead of letting
+you do that.
+
+[endsect]
+[section Is `return_internal_reference` efficient?]
+
+[*Q:] /I have an object composed of 12 doubles. A `const&` to
+this object is returned by a member function of another class. From the
+viewpoint of using the returned object in Python I do not care if I get
+a copy or a reference to the returned object. In Boost.Python I have the
+choice of using `copy_const_reference` or `return_internal_reference`.
+Are there considerations that would lead me to prefer one over the other,
+such as size of generated code or memory overhead?/
+
+[*A:] `copy_const_reference` will make an instance with storage
+for one of your objects, `size = base_size + 12 * sizeof(double)`.
+`return_internal_reference` will make an instance with storage for a
+pointer to one of your objects, `size = base_size + sizeof(void*)`.
+However, it will also create a weak reference object which goes in the
+source object's weakreflist and a special callback object to manage the
+lifetime of the internally-referenced object. My guess?
+`copy_const_reference` is your friend here, resulting in less overall
+memory use and less fragmentation, also probably fewer total
+cycles.
+
+[endsect]
+[section How can I wrap functions which take C++ containers as arguments?]
+
+Ralf W. Grosse-Kunstleve provides these notes:
+
+# Using the regular `class_<>` wrapper:
+  ``
+    class_<std::vector<double> >("std_vector_double")
+      .def(...)
+      ...
+    ;
+  ``
+  This can be moved to a template so that several types (`double`, `int`,
+  `long`, etc.) can be wrapped with the same code. This technique is used
+  in the file `scitbx/include/scitbx/array_family/boost_python/flex_wrapper.h`
+  in the "scitbx" package. The file could easily be modified for
+  wrapping `std::vector<>` instantiations.
+  This type of C++/Python binding is most suitable for containers
+  that may contain a large number of elements (>10000).
+
+# Using custom rvalue converters. Boost.Python "rvalue converters"
+  match function signatures such as:
+  ``
+    void foo(std::vector<double> const &array); // pass by const-reference
+    void foo(std::vector<double> array); // pass by value
+  ``
+  Some custom rvalue converters are implemented in the file
+  `scitbx/include/scitbx/boost_python/container_conversions.h`
+  This code can be used to convert from C++ container types such as
+  `std::vector<>` or `std::list<>` to Python tuples and vice
+  versa. A few simple examples can be found in the file
+  `scitbx/array_family/boost_python/regression_test_module.cpp`
+  Automatic C++ container <-> Python tuple conversions are most
+  suitable for containers of moderate size. These converters generate
+  significantly less object code compared to alternative 1 above.
+
+A disadvantage of using alternative 2 is that operators such as
+arithmetic +,-,*,/,% are not available. It would be useful to have custom
+rvalue converters that convert to a "math_array" type instead of tuples.
+This is currently not implemented but is possible within the framework of
+Boost.Python V2 as it will be released in the next couple of weeks. [ed.:
+this was posted on 2002/03/10]
+
+It would also be useful to also have "custom lvalue converters" such
+as `std::vector<>` <-> Python list. These converters would
+support the modification of the Python list from C++. For example:
+
+C++:
+``
+  void foo(std::vector<double> &array)
+  {
+    for(std::size_t i=0;i&lt;array.size();i++) {
+      array[i] *= 2;
+    }
+  }
+``
+Python: [python]
+``
+  >>> l = [1, 2, 3]
+  >>> foo(l)
+  >>> print l
+  [2, 4, 6]
+``
+Custom lvalue converters require changes to the Boost.Python core library
+and are currently not available.
+
+P.S.:
+
+The "scitbx" files referenced above are available via anonymous
+CVS:
+``
+  cvs -d:pserver:anonymous@cvs.cctbx.sourceforge.net:/cvsroot/cctbx login
+  cvs -d:pserver:anonymous@cvs.cctbx.sourceforge.net:/cvsroot/cctbx co scitbx

+[section fatal error C1204:Compiler limit:internal structure overflow]
+
+[*Q:] /I get this error message when compiling a large source file. What can I do?/
+
+[*A:] You have two choices:
+
+# Upgrade your compiler (preferred)

+# Break your source file up into multiple translation units.

+  ``
+  If you find that a `class_<...>` declaration
+  can't fit in a single source file without triggering the error, you
+  can always pass a reference to the `class_` object to a

+  functions (e.g. `.def(...)`) in the auxilliary source
+  file:
+
+  `more_of_my_class.cpp`:
+  ``
+    void more_of_my_class(class&lt;my_class&gt;&amp; x)
+    {
+      x
+       .def("baz", baz)
+       .add_property("xx", &my_class::get_xx, &my_class::set_xx)
+       ;
+      ...
+    }

+[section How do I debug my Python extensions?]
+
+Greg Burley gives the following answer for Unix GCC users:
+
+[:Once you have created a boost python extension for your c++ library or
+  class, you may need to debug the code. Afterall this is one of the
+  reasons for wrapping the library in python. An expected side-effect or
+  benefit of using BPL is that debugging should be isolated to the c++
+  library that is under test, given that python code is minimal and
+  boost::python either works or it doesn't. (ie. While errors can occur
+  when the wrapping method is invalid, most errors are caught by the
+  compiler ;-).
+
+  The basic steps required to initiate a gdb session to debug a c++
+  library via python are shown here. Note, however that you should start
+  the gdb session in the directory that contains your BPL my_ext.so
+  module.
+
+  ``
+    (gdb) target exec python
+    (gdb) run
+    >>> from my_ext import *
+    >>> [C-c]
+    (gdb) break MyClass::MyBuggyFunction
+    (gdb) cont
+    >>> pyobj = MyClass()
+    >>> pyobj.MyBuggyFunction()
+    Breakpoint 1, MyClass::MyBuggyFunction ...
+    Current language:  auto; currently c++
+    (gdb) do debugging stuff
+  ``
+]
+
+Greg's approach works even better using Emacs' "gdb"
+command, since it will show you each line of source as you step through it.
+
+On *Windows*, my favorite debugging solution is the debugger that
+comes with Microsoft Visual C++ 7. This debugger seems to work with code
+generated by all versions of Microsoft and Metrowerks toolsets; it's rock
+solid and "just works" without requiring any special tricks from the
+user.
+
+Raoul Gough has provided the following for gdb on Windows:
+
+[:gdb support for Windows DLLs has improved lately, so it is
+  now possible to debug Python extensions using a few
+  tricks. Firstly, you will need an up-to-date gdb with support
+  for minimal symbol extraction from a DLL. Any gdb from version 6
+  onwards, or Cygwin gdb-20030214-1 and onwards should do. A
+  suitable release will have a section in the gdb.info file under
+  Configuration - Native - Cygwin Native -
+  Non-debug DLL symbols. Refer to that info section for more
+  details of the procedures outlined here.
+
+  Secondly, it seems necessary to set a breakpoint in the
+  Python interpreter, rather than using ^C to break execution. A
+  good place to set this breakpoint is PyOS_Readline, which will
+  stop execution immediately before reading each interactive
+  Python command. You have to let Python start once under the
+  debugger, so that it loads its own DLL, before you can set the
+  breakpoint:
+
+  ``
+    $ gdb python
+    GNU gdb 2003-09-02-cvs (cygwin-special)
+    [...]
+
+    (gdb) run

+
+[h2 Debugging extensions through Boost.Build]
+
+If you are launching your extension module tests with _bb_ using the
+`boost-python-runtest` rule, you can ask it to launch your
+debugger for you by adding "--debugger=/debugger/" to your bjam
+command-line:
+``
+  bjam -sTOOLS=vc7.1 "--debugger=devenv /debugexe" test
+  bjam -sTOOLS=gcc -sPYTHON_LAUNCH=gdb test
+``
+It can also be extremely useful to add the `-d+2` option when
+you run your test, because Boost.Build will then show you the exact
+commands it uses to invoke it. This will invariably involve setting up
+PYTHONPATH and other important environment variables such as
+LD_LIBRARY_PATH which may be needed by your debugger in order to get
+things to work right.

+[section Why doesn't my `*=` operator work?]
+
+[*Q:] ['I have exported my class to python, with many overloaded
+operators. it works fine for me except the `*=`
+operator. It always tells me "can't multiply sequence with non int
+type". If I use `p1.__imul__(p2)` instead of
+`p1 *= p2`, it successfully executes my code. What's
+wrong with me?]
+
+[*A:] There's nothing wrong with you. This is a bug in Python
+      2.2. You can see the same effect in Pure Python (you can learn a lot
+      about what's happening in Boost.Python by playing with new-style
+      classes in Pure Python).
+``
+>>> class X(object):
+...     def __imul__(self, x):
+...         print 'imul'
+...
+>>> x = X()
+>>> x *= 1
+``
+To cure this problem, all you need to do is upgrade your Python to
+version 2.2.1 or later.
+
+[endsect]
+[section Does Boost.Python work with Mac OS X?]
+
+It is known to work under 10.2.8 and 10.3 using
+Apple's gcc 3.3 compiler:
+``gcc (GCC) 3.3 20030304 (Apple Computer, Inc. build 1493)``
+Under 10.2.8 get the August 2003 gcc update (free at [@http://connect.apple.com]).
+Under 10.3 get the Xcode Tools v1.0 (also free).
+
+Python 2.3 is required. The Python that ships with 10.3 is
+fine. Under 10.2.8 use these commands to install Python
+as a framework:
+``./configure --enable-framework
+make
+make frameworkinstall``
+
+The last command requires root privileges because the target
+directory is `/Library/Frameworks/Python.framework/Versions/2.3`.
+However, the installation does not interfere with the Python
+version that ships with 10.2.8.
+
+It is also crucial to increase the `stacksize` before
+starting compilations, e.g.:
+``limit stacksize 8192k``
+If the `stacksize` is too small the build might crash with
+internal compiler errors.
+
+Sometimes Apple's compiler exhibits a bug by printing an error
+like the following while compiling a
+`boost::python::class_<your_type>`
+template instantiation:
+``
+  .../inheritance.hpp:44: error: cannot
+    dynamic_cast `p' (of type `struct cctbx::boost_python::<unnamed>::add_pair*
+    ') to type `void*' (source type is not polymorphic)

+``

+[section How can I find the existing PyObject that holds a C++ object?]
+
+[: "I am wrapping a function that always returns a pointer to an
+      already-held C++ object."]
+
+One way to do that is to hijack the mechanisms used for wrapping a class
+with virtual functions. If you make a wrapper class with an initial
+PyObject* constructor argument and store that PyObject* as "self", you
+can get back to it by casting down to that wrapper type in a thin wrapper
+function. For example:
+``
+  class X { X(int); virtual ~X(); ... };
+  X* f();  // known to return Xs that are managed by Python objects
+
+
+  // wrapping code
+
+  struct X_wrap : X
+  {
+    X_wrap(PyObject* self, int v) : self(self), X(v) {}
+    PyObject* self;
+  };
+
+  handle<> f_wrap()
+  {
+    X_wrap* xw = dynamic_cast<X_wrap*>(f());
+    assert(xw != 0);
+    return handle<>(borrowed(xw->self));
+  }
+
+  ...
+
+  def("f", f_wrap());
+  class_<X,X_wrap,boost::noncopyable>("X", init<int>())
+   ...
+   ;
+``
+
+Of course, if X has no virtual functions you'll have to use
+`static_cast` instead of `dynamic_cast` with no
+runtime check that it's valid. This approach also only works if the
+`X` object was constructed from Python, because
+`X`\ s constructed from C++ are of course never
+`X_wrap` objects.
+
+Another approach to this requires you to change your C++ code a bit;
+if that's an option for you it might be a better way to go. work we've
+been meaning to get to anyway. When a `shared_ptr<X>` is
+converted from Python, the shared_ptr actually manages a reference to the
+containing Python object. When a shared_ptr<X> is converted back to
+Python, the library checks to see if it's one of those "Python object
+managers" and if so just returns the original Python object. So you could
+just write `object(p)` to get the Python object back. To
+exploit this you'd have to be able to change the C++ code you're wrapping
+so that it deals with shared_ptr instead of raw pointers.
+
+There are other approaches too. The functions that receive the Python
+object that you eventually want to return could be wrapped with a thin
+wrapper that records the correspondence between the object address and
+its containing Python object, and you could have your f_wrap function
+look in that mapping to get the Python object out.

+[section How can I wrap a function which needs to take ownership of a raw pointer?]
+
+[*Q:] Part of an API that I'm wrapping goes something like this:
+
+``
+  struct A {}; struct B { void add( A* ); }
+  where B::add() takes ownership of the pointer passed to it.
+``
+
+However:
+
+``
+  a = mod.A()
+  b = mod.B()
+  b.add( a )
+  del a
+  del b
+  # python interpreter crashes
+  # later due to memory corruption.
+``
+
+Even binding the lifetime of a to b via `with_custodian_and_ward` doesn't prevent
+the python object a from ultimately trying to delete the object it's pointing to.
+Is there a way to accomplish a 'transfer-of-ownership' of a wrapped C++ object?
+
+--Bruce Lowery
+
+Yes: Make sure the C++ object is held by auto_ptr:
+``
+  class_<A, std::auto_ptr<A> >("A")
+    ...
+    ;
+``
+Then make a thin wrapper function which takes an auto_ptr parameter:
+``
+  void b_insert(B &b, std::auto_ptr<A> a)
+  {
+    b.insert(a.get());
+    a.release();
+  }
+``
+Wrap that as B.add. Note that pointers returned via `manage_new_object`
+will also be held by `auto_ptr`, so this transfer-of-ownership
+will also work correctly.

+
+/Niall Douglas provides these notes:/
+
+If you see Microsoft Visual C++ 7.1 (MS Visual Studio .NET 2003) issue
+an error message like the following it is most likely due to a bug
+in the compiler:
+``
+  boost\boost\python\detail\invoke.hpp(76):
+  error C2064: term does not evaluate to a function taking 2 arguments"
+``
+This message is triggered by code like the following:
+``
+  #include <boost/python.hpp>
+
+  using namespace boost::python;
+
+  class FXThread
+  {
+  public:
+    bool setAutoDelete(bool doso) throw();

+  {
+    class_< FXThread >("FXThread")
+        .def("setAutoDelete", &amp;FXThread::setAutoDelete)
+    ;
+  }
+``
+The bug is related to the `throw()` modifier.
+As a workaround cast off the modifier. E.g.:
+``
+   .def("setAutoDelete", (bool (FXThread::*)(bool)) &FXThread::setAutoDelete)
+``
+(The bug has been reported to Microsoft.)

+[section How can I automatically convert my custom string type to and from a Python string?]
+
+/Ralf W. Grosse-Kunstleve provides these notes:/
+
+Below is a small, self-contained demo extension module that shows
+how to do this. Here is the corresponding trivial test:
+``
+  import custom_string
+  assert custom_string.hello() == "Hello world."
+  assert custom_string.size("california") == 10
+``
+If you look at the code you will find:
+
+* A custom `to_python` converter (easy):
+        `custom_string_to_python_str`
+
+*A custom lvalue converter (needs more code):
+        `custom_string_from_python_str`
+
+The custom converters are registered in the global Boost.Python
+registry near the top of the module initialization function. Once
+flow control has passed through the registration code the automatic
+conversions from and to Python strings will work in any module
+imported in the same process.

+[section Why is my automatic to-python conversion not being found?]
+
+/Niall Douglas provides these notes:/
+
+If you define custom converters similar to the ones
+shown above the `def_readonly()` and `def_readwrite()`
+member functions provided by `boost::python::class_` for
+direct access to your member data will not work as expected.
+This is because `def_readonly("bar",&foo::bar)` is
+equivalent to:
+
+``
+  .add_property("bar", make_getter(&foo::bar, return_internal_reference()))
+``
+Similarly, `def_readwrite("bar",&foo::bar)` is
+equivalent to:
+
+``
+  .add_property("bar", make_getter(&foo::bar, return_internal_reference()),
+                     make_setter(&foo::bar, return_internal_reference())
+``
+In order to define return value policies compatible with the
+custom conversions replace `def_readonly()` and
+`def_readwrite()` by `add_property()`. E.g.:
+
+``
+  .add_property("bar", make_getter(&foo::bar, return_value_policy<return_by_value>()),
+                     make_setter(&foo::bar, return_value_policy<return_by_value>()))

+[section Is Boost.Python thread-aware/compatible with multiple interpreters?]
+
+/Niall Douglas provides these notes:/
+
+The quick answer to this is: no.
+
+The longer answer is that it can be patched to be so, but it's
+complex. You will need to add custom lock/unlock wrapping of every
+time your code enters Boost.Python (particularly every virtual
+function override) plus heavily modify
+`boost/python/detail/invoke.hpp` with custom unlock/lock
+wrapping of every time Boost.Python enters your code. You must
+furthermore take care to /not/ unlock/lock when Boost.Python
+is invoking iterator changes via `invoke.hpp`.
+
+There is a patched `invoke.hpp` posted on the C++-SIG
+mailing list archives and you can find a real implementation of all
+the machinery necessary to fully implement this in the TnFOX
+project at [@http://sourceforge.net/projects/tnfox/ this]
+SourceForge project location.
