[Haskell-cafe] Idea for a tool

Alright, the tool is up and incredibly basic right now. Go to:
http://packdeps.haskellers.com/, type a search string, and hit enter.
The site will filter through all of the cabal files for the most
recent releases of each package and select the ones where your search
string appears in the package name, maintainer and/or author fields.
>From those packages, it will check to see if there are any
upper-bounds restrictions excluding a package. The results are
returned as an Atom feed, so you can easily add this to a reader or
maybe even sign up for email alerts.
Let me know if there are any bugs, eventually I'll put up some proper
information on the page describing what's going on there. Oh, and the
package database gets refreshed every 6 hours.
