I haven't used Swig, so I can't really compare them. Using
Boost.Python is pretty easy once you get into it, but it will probably
take a little bit of effort to get there (see the tutorial to get an

Boost.Python doesn't provide a lot of support for embedding Python. It
does basic stuff like managing reference counts for you and so on, but
doesn't currently wrap much of the Python/C API.

I guess anything is possible since you have access to the Python
source code and could relink it anyway you want, given enough
effort. You'd probably do better to ask about this on the main Python
discussion group, since it's not specifically C++ related. I'm not
sure about any legal/licensing issues of doing this, and how much of
the Python library (i.e. .py or .pyc files) the interpreter needs to
have to get going.
