Yes, that might be a help. I think the confusion is in the name

The _fwd could signify either two things:

   (1) The header includes only forward declarations. Like the
        standard's <iosfwd>

   (2) The header just forwards to other headers. For example,
        <boost/smart_ptr.hpp> contains only:

          #include <boost/scoped_ptr.hpp>
          #include <boost/scoped_array.hpp>
          #include <boost/shared_ptr.hpp>
          #include <boost/shared_array.hpp>

Personally, I'd like to reserve appending "_fwd" for case (1), but would
also like to hear other's opinions.

In which sense are you using "_fwd"?

Aside from that one header name question, is the library ready to be
committed to CVS?
