+This example uses boost v1.55 because later versions appear to have problems building boost.python on windows.
+
+Download boost and build boost.python. You may have to play with the options to get the right filename to be generated.
+`G:\Libraries\boost\boost_1_55_0>b2 -j4 --with-python variant=debug address-model=32 link=shared,static runtime-debugging=on  toolset=msvc-14.0 -a`
+
+In this case we are looking for `boost_python3-vc140-mt-gd-1_55.lib` which is actually an import library and not a static library, and `boost_python3-vc140-mt-gd-1_55.dll`.

+decoding boost names
+--------------------
+vc140 - compiler
+mt - multithreading
+gd - runtime debugging and debug symbols
+
+Common Problems
+===============
+
+'2to3' is not recognized
+------------------------
+running tests with bjam seems to fail with '2to3' is not recognized as a internal or external command...
+
+You should have python.exe in C:\Python35 and 2to3.py in C:\Python35\Tools\Scripts.
+
+Create a batch file called 2to3.bat in C:\Python35 and put this line in the batch file
+
+python %~dp0Tools\Scripts\2to3.py %*
+
+VS wants to use vc120 instead of vc140
+--------------------------------------
+get the error LNK1104: cannot open file 'boost-python-vc120-mt-1_55.lib' in visual studio 2015 (vc140), and the project compiler is set to the v140?
+
+Boost 1.55 is too old to know about v140, so you need to edit boost/config/auto_link.hpp:
+
+#  elif defined(BOOST_MSVC) && (BOOST_MSVC < 1900)
+#    define BOOST_LIB_TOOLSET "vc120"
+
+#  elif defined(BOOST_MSVC)
+#    define BOOST_LIB_TOOLSET "vc140"
