file_configuration_t is rather cool feature. When you create module_builder_t
class instance you should pass list of files. This list can contain
string( == file paths ) and/or instances of file_configuration_t
class.

file_configuration_t is class with fat interface.
It has 4 states:
   1. it could contain reference to source file.
        Use "create_source_fc" function to create an instance of
file_configuration_t

   2. it could contain reference to source file and xml file. In this
case if xml file
       exist, source file will not be parsed by gccxml. If xml file
does not exists, source
       file will be parsed and xml file will be saved for future use.
       See create_cached_source_fc function

   3. it could contain reference to xml file only
       See create_gccxml_fc

   4. it could contain some text. In this case, parser will create
temporal file on
       disk and will pass it as an argument to gccxml.
       See create_text_fc

In most cases you don't all those features. If I were you, I would
create regular
source file and put all template instantiation there.

Any way the code:

tmpl_inst = """
=====================
  #include "TempClass.h"

  namespace details{
     inline void export_templates(){
         sizeof( TempClass<int> );
     }
 }
"""
import module_builder
mb = module_builder.module_builder_t(
    [ module_builder.create_text_fc( tmpl_inst ) ]
    , .... )

Do you understand it know?
