beginner questions on embedding/extending python with C++

[Hoop]

Hi All,
I am in the process also of trying to call Python script from a C++
windows app.
I have looked at the Boost site and am currently reading over the
Embedding portion of the tutorial. A question I have is that there
appear to be about 4 or 5 Boost items avaiable for download. Which one
should be downloaded to do the embedding?
Thanks
Jeff
