title: How to set a program's command line arguments for GHCi?
body: <p>Suppose some Haskell file is executed with</p>
  
  <pre><code>runghc Queens.hs gecode_compile
  </code></pre>
  
  <p>Now, this fails, and I want to debug it with <code>ghci</code>. How do I pass the option <code>gecode_compile</code> into the program, so <code>getArgs</code> will read it correctly?</p>
  
  <p>Thanks!!</p>
