I've written a little C++ program to do that.  Thanks to the boost regular 
expression library for making it easy!

There are three sets of options, each with two possibilities:

*  Show a header name:
      -  once at highest level encountered
      -  each time encountered

*  Include or exclude Standard Library headers

*  Include or exclude detail implementation headers

To see the result on boost/regex.hpp for all eight combinations, see
http://www.egroups.com/files/boost/regex_dependencies.txt

I think I prefer the first combination: show names once, include std names, 
include implementation detail headers.

Comments?
