Hi Tim,

Sorry for my delay.  I think I’m finally starting to understand your patch.

Yeah it would be nice if it were automatically tracked or if the env vars were 
respected.

I like the idea of offering more cabal file semantics to package authors. In 
that regards I have no issues with your patches.  My only thought is we should 
make the flags lists instead of booleans. Not only would lists match the cabal 
file specification, but I think having the extra detail would be a nice way to 
verify against existing cabal files. I can’t imagine just yet how but I could 
see wanting to be able to specify which paths were being used and their order.

I am not opposed to the names of the fields either, I like that they match the 
cabal fields.

Thanks again!

John
