[Hat] Proposal, Heirarchical module structure for tools

[Neil Mitchell]

Hi,

> Interesting.  Okay, so my question then is, where would something like EDT.hs or SExp.hs go?  They aren't libraries for one tool, they aren't commonly used and they aren't one tool.

Hat.Lib.SExp and Hat.Lib.EDT, they are libraries - things in Hat.Lib
don't have to be for one tool, they just have to be libraries. Part of
the hope of this exercise would be that the one tool - one library
model goes away slowly, as the tools start to share more and more
library code.

Thanks

Neil
