In which case it may be simpler just to download it to the cache and then cp. Fewer different code paths. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/453#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

Adding an extra command line arg is easy as is adding the plumbing to get the info to the right place. The only tricky thing is that for `fetch -o` we do not care about dependencies so we should use the logic for `unpack` rather than the normal `fetch`. Bonus points for refactoring to unify the two methods and using a parameter to specify if we want to download deps into the cache too. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/453#comment:9 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
