title: Stack Build within Haskell
body: <p>I want to be able to call stack from within haskell to build a project for me. Nothing in the documentation explains this and going through <code>src/main/Main.hs</code> has been difficult to understand what function is the correct to use.</p>
  
  <p>CLI version of what I want to run with imported stack functions:</p>
  
  <pre><code>stack build --fast
  </code></pre>
  
  <p>Explicitly not using calls to bash.</p>
