[arch-haskell] Road to binary repository

I see. I was confused because the instructions in the README file say
that users are supposed to re-generate PKGLIST.

I may be misunderstanding things, of course, but this sounds very much
like the short answer to my question is "no". 

Does it even make sense to implement all those features that you've
mentioned? From the looks of it, you are about to re-invent Make.

Take care,
