I think we already have parser for Jamfile -- the one in Jam. Integrating that
with Python solution (whatever specific design is used) should be simple.

OTOH, I believe that preserving Jamfiles is an important goal. It's kind of
"marketing" point. Even if Boost.Build is not yet 2.0-final and we made no
promises, breaking compatibility will cause much troubles for users. Even
imagine that a project works fine with 2.0-m11 but does not work with (say)
2.0-m12. Everybody will be upset with how Boost.Build is incompatible with
