title: How to tell HSpec where to look for the source files to be tested
body: <p>I'm new to Haskell and I wanted to add tests to my first project. I chose HSpec for this. My only spec file doesn't contain anything special so far. I just copied the example from the HSpec website and added <code>import</code> statements for my own modules to be tested. When I try to run it via <code>runhaskell test/XSpec.hs</code> it complains that it "could not find module X". How do I tell it about the load paths it should take a look into before complaining?</p>
