Please do not top post.

The -I option sets the include path. If you set it to the directory 
where Boost is installed on your system, then Boost header files will be 
found, since all Boost header files are of the form of:

#include <boost/some_path/some_headerfile.hpp>

the 'boost' subdirectory ( and its subdirectories ) for each 
distribution is where the Boost header files reside.
