I don't think it does in general. I want to be able to check this in and 
have it run while building the official docs. I can't count on $INCLUDE 
being set on whatever machine does that, or on the machine of J. Random 
User who wants to build the docs for him/herself. I had hoped that 
Boost.Build would help, but it seems there is no way to extract this 
information from BBv2.
