+
+# Synopsis
+
+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 ![Build Status](https://travis-ci.org/boostorg/python.svg?branch=develop)
+
+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.
+
+## Prerequisites
+
+* [Python](http://www.python.org)
+* [Boost](http://www.boost.org)
+* [SCons](http://www.scons.org)
+
+## Configure
+
+Simply run
+
+```
+scons config [options]
+```
+to prepare a build. See `scons -h` for a description of the available options. For example
+```
+scons config --boost=/path/to/boost --python=/path/to/python
+```
+will configure Boost.Python to be built against the two specific versions of Boost and Python.
+
+## Build
+
+Run
+
+```
+scons
+```
+to build the library.
+
+## Test
+
+Run
+
+```
+scons test
+```
+to run the tests.
+
+## Build docs
+
+Run
+
+```
+scons doc
+```
+to build the documentation.

+"""SCons.Tool.spinx4scons
+
+Tool-specific initialization for the Sphinx document build system.
+
+There normally shouldn't be any need to import this module directly.
+It will usually be imported through the generic SCons.Tool.Tool()
+selection method.
+
+It should be placed in e.g. ~/site_scons/site_tools/sphinx4scons/
+directory. Then it may be loaded by placing
+
+  sphinx = Tool('sphinx4scons')
+  sphinx(env)
+
+in your SConstruct file.
+
+For further details, please see the SCons documentation on how to
+install and enable custom tools.
