"Setup.lhs: hope.cabal has been changed, please re-configure."

Hello, Thanks for your efforts with Cabal, it seems to work really well. Can I suggest a few improvements to the above error message: 1. Provide a flag "--force" that says "OK, the user knows best." (Sometimes I change the .cabal file trivially, and really just want to build the thing.) Indeed, a lot of commands might usefully be "--force"d. 2. It is a bit unsound to say "please re-configure". You may also need to "clean", if in fact the .cabal file has changed significantly. So, to say that another way, the message provides both insufficient and unnecessary advice, but I think it can be improved. cheers peter
