Athas on #haskell wondered how many dependencies the average Haskell
package had. I commented that it seemed like some fairly simple
scripting to find out, and as these things tend to go, I wound up
doing a complete solution myself.
First, we get most/all of Hackage locally to examine, as tarballs

Excluding, it seems. When I run the script on that tarball:
$ tar --wildcards "*.cabal" -Oxf `find . -name "*.tar.gz" | g hugs2yc`

Looking
Another thing you can do along the same lines is generate a script to
download all the repos from packages which declare repos. Some ugly
code:
import Data.Maybe (fromJust)
import Distribution.PackageDescription
import Distribution.PackageDescription.Parse
import Control.Monad (unless)
main :: IO
