You can find a reasonable up-to-date version at

https://svn.boost.org/svn/boost/sandbox/python_extensions

There are a lot of other little extensions there too; you'll be most 
interested in the const_aware subdirectories.  It's highly likely the 
build system is broken, but the code itself should still work.  The best 
documentation is probably the const_aware example in the tests.

Adding this to Boost.Python proper is a big part of my plans for a 
Boost.Python v3, but that's still a ways off, and unfortunately the code 
I'm pointing you at may have suffered from a little bitrot as I haven't 
looked at it in a while.
