Hello,

I want to integrate documentation that uses its own build system. (The
Boost.Python NumPy extension uses sphinx.)

What do I need to add to my Jamfile to run `make` in addition to copying
a few directories around ?


Specifically, I have this directory structure:

python/doc/

                  Jamfile

                   numpy/

                               Makefile

                               make.bat


and I want to generate `python/doc/html/numpy/` ? (I suppose, to follow
BB conventions I should copy the `numpy/` subdirectory above into
bin.v2/, invoke `make` there, then copy the generatd `html/` directory
back into `python/doc/html/numpy`.)

What do I need to do here ? Define a rule ? Use an existing rule with a
custom action ? I'd appreciate if someone could give me some directions.
