Qustions about hierarchaly library conventions

[Matthew Donadio]

Hi all,

I have a qustion about a convention when writing a hierarchal library.

Lets say I have a library

	A.B.C

with modules

	A.B.C
	     C1.hs
	     C2.hs
	     C3.hs

Is there a convention (official or not) as to when there is a parent
module (in the example above, C.hs) that imports and re-exports the
various sub-modules?

For example, in the standard libraries, there is a Foreign module that
re-exports most of Foreign.*.  But there isn't a System.Posix; you have
to import the System.Posix.Signal and System.Posix.Types individually.

Thanks.
