Comment:

 You can choose your own mapping between filenames and module names as long
 as you tell GHC about all the filenames in your project.  For example:

 {{{
 $ cat >Foo.Burble.hs
 module Foo.Burble where
 $ cat >Bar.Mumble.hs
 module Bar.Mumble where
 import Foo.Burble
 $ cat >MyProg.hs
 module Main where
 import Foo.Burble
 import Bar.Mumble
 main = print "hello"
 $ ghc --make MyProg.hs Foo.Burble.hs Bar.Mumble.hs
 [1 of 3] Compiling Foo.Burble       ( Foo.Burble.hs, Foo.Burble.o )
 [2 of 3] Compiling Bar.Mumble       ( Bar.Mumble.hs, Bar.Mumble.o )
 [3 of 3] Compiling Main             ( MyProg.hs, MyProg.o )
 Linking MyProg ...
 }}}

 So your "manifest" might just be a list of filenames that you pass to ghc
 using {{{ghc --make `cat manifest`}}}.

 This doesn't let you put multiple modules in one file, of course.  Also, I
 don't think you can do this with Cabal (or maybe you can?).
