Right! > If this field is set to something other than Custom, cabal-setup can > ignore Setup.lhs, and just do the appropriate thing itself (making > Setup.lhs optional). That's a good idea. People can include Setup.lhs to be backward compatible, but if the Build-Type field is Custom (for instance) we can ignore it. I guess if they say "Custom" then we look for Setup.lhs only, (and maybe Setup.hs to give a helpful hint). I think I mentioned the idea of letting them give an arbitrary path, but that just seems like a bad idea. > For backward compatibility, you'd probably want the default value of > the new field to be Custom, though this would mean you couldn't omit > Setup.lhs unless this field was set. Right. >> Ross, how do you see the fields panning out?

What do others think of all this? peace, isaac _______________________________________________ cabal-devel mailing list cabal-devel@haskell.org http://www.haskell.org/mailman/listinfo/cabal-devel
