I have forked boost math library on GitHub and want to make some
testing. However, I have three issues to ask you:

* Which branch does the quadrature exist in? develop or other branch?
* Can I build boost library just only with math module? I guess, I
  should checkout all of boost modules in order to success in
  building boost library.

    JMvB> will need to navigate to the tools->quadrature section (page 745).
* Can you tell how to build Boost.math documentation? I found it is
  diffcult to build Boost documentations by boostbook. Is there any
  guideline to do this?
