Can I get Doxygen to merge namespace contents in different files?

Question

I have different .h files that each provide declarations in the same namespace. Doxygen generates a new entry for each file, with the same name. Can I make doxygen to merge all these?

Answer 1

Add at least one documented namespace declaration. I'm using to do this in a separate header file, that contains documentation global definitions (main page, groups, etc.) for the project's root namespace.
