Comments in header files are not automatically available to edoc.
There are several reasons for this: first, it would cause
duplication of the documentation (in each module that includes
the header); second, the place where the -include(...) directive
occurs is not necessarily where the information from the header
file should be "inserted"; and third, it would require that you
told edoc the exact include-path to be used for compilation of
the module, so it could find the header files (which are not
always in the same directory as the source file).

There is however an experimental, as yet undocumented tag,
@headerfile "foo.hrl" that you can try out. It explicitly
includes tags from a header file at the place where the tag
occurs. It will probably be made an official tag, so I think
it's fairly safe to start using.
