These lines in the Organization | Layers section of the fusion documentation baffle me:

'Each module has its own header file placed in the same directory with the actual module-directory. For example, there exists "boost/fusion/support.hpp" in the same directory as "boost/fusion/support".'

I can see a "boost/fusion/support.hpp" file as well as a "boost/fusion/support" subdirectory. If I look at "boost/fusion/support.hpp" it includes a number of header files in the "boost/fusion/support" subdirectory.

But what the two lines quoted in the documentation above are saying eludes me. If it is saying what I discovered, it is not explaining things correctly.

Hi Edward,

Yes, it is saying just that. Any suggestion on how the doc could be improved is highly appreciated. Thanks!

'Each module has its own header file placed in the same directory with the actual module-directory. For example, there exists "boost/fusion/support.hpp" in the same directory as "boost/fusion/support".' should be: 'Each module has its own header file placed in the main boost/fusion directory. This header file includes all of the relevant header files in the appropriate module subdirectory. For example, there exists "boost/fusion/support.hpp" which includes the header files in the "boost/fusion/support" subdirectory.'

This is not quite accurate. The sub-modules/directories also follow the same convention.

I am not sure what you mean by '...follow the same convention.' In my Boost 1.36 directory tree I see a fusion support.hpp in the boost/fusion directory but I do not see a support.hpp in the boost/fusion/support directory. Likewise for every other fusion sub-module. Maybe I should have suggested the correction be written 'Each module has its main header file placed in the boost/fusion directory'.

Ok, thanks!
