It really isn’t. Maybe we should just set up an equivalent to
http://githubredir.debian.net/ which periodically downloads the indices
form Hackage and creates a nice parsable overview page.

Another idea: If we use 
as the page to scrape all versions from, we don’t need to hammer their
CGI scripts (which is nice), no special treatment of the latest version
and probably more robust and the package name occurs only once:

opts=downloadurlmangle=s|archive/([\w\d_-]+)/([\d\.]+)/|archive/$1/$2/$1-$2.tar.gz| \
    http://hackage.haskell.org/packages/archive/arrows \

I guess with this solution, unless you find a bug with it, we should use
this and not spend effort in re-creating an hackage interface.
