Hi!

I finish writing my proposal (maybe a bit too late). I would be glad to read any feedback.

Hi Diego, Generally a good proposal. It would be great for Cabal's "Simple" build system to be able deal with pre-processor chaining and with pre-processors that do not have a simple 1:1 relationship between .hs and other source files. Here are two closely related issues you might like to think about: * pre-processors that have inter-module dependencies (e.g. c2hs) * pre-processors that generate modules from "nothing" ie there is no special file extension, simply a program that generates a specific module. This is common for things like adding the darcs context, or project-specific generation. Duncan
