I think changing Setup.(l)hs definition with UserHook
is very strong, but this approach is too complex to
specify just generating file from other resources
by only one tool.

I think cabal must support to write using self
preproccesser definition in *.cabal files like this.


name: hdirect
version: 0.1
(snip)
othermodules: ComPrim, AutoPrim

generatable: ComPrim
g-sources: ComPrim.idl
g-tool: ihc
g-option: -fno-export-list -fappend-interface-short-name  
-fno-qualified-names -fno-imports -fno-export-lists -fkeep-hresult  
-fout-pointers-are-not-refs

generatable: AutoPrim
g-sources: AutoPrim.idl
g-tool: ihc
g-option: -fno-qualified-names -fno-imports -fno-export-lists  
-fkeep-hresult -fout-pointers-are-not-refs


This is rough sketch. But I think this is useful for
discussion about "Cabal with Generating files".
