[Boost-users] compile time (template or preprocessor) text processing

Hello,

My question is c++ related (I like to call the topic extreme c++ programming). 
We all know the excellent boost python framework, which exports c++ functions 
to python with spectacular elegance. As for the documentation of those 
functions boost offers a string parameter, which can contain the description 
of the particular function. Sometimes this documentation is already written 
(for example in doxygen). It would be good to import this documentation 
somehow to python.

Is there a possibility to generate a std::string from a FILE following some 
rules using template meta-programming (or possibly the preprocessor)?

For example

my_function.cpp

///*************
// this is the documentation of my_function
//
void my_function()
{
cout << "I've been called.\n"
}

boost_export.cpp

def( 
"my_function", 
&my_function, 
(args()),
generate_the_doc_in_compile_time_from<>("my_function.cpp") 
)

Here the generate_the_doc_in_compile_time_from<>("my_function.cpp") would 
hard-wire the docs into def at compile time, so it would no longer depend on 
my_function.cpp.

Any ideas would be greatly appreciated.
