title: How to (install and) use package in haskell
body: <p>I'm trying to use <a href="http://hackage.haskell.org/package/xml" rel="nofollow noreferrer">this xml package</a> in ghci.</p>
  <p>What I already did in cmd:</p>
  <blockquote>
  <p>cabal install cabal-install</p>
  <p>cabal install xml-1.3.13.tar.gz</p>
  </blockquote>
  <p>And the installation was succesful.
  But how do I use this package inside my scripts and GHCi? I'm about to throw my pc out of the window atm...</p>
