title: Typesafe Config: How to Create Conditional Configurations
body: <p>Does Typesafe Config allow to create conditional configurations?</p>
  
  <p>I need to set a key depending on the value of another key:</p>
  
  <pre><code>ssl = true
  
  #if ssl == true
  host = "https://localhost"
  #else
  host = "http://localhost"
  #end if
  </code></pre>
  
  <p>Of course the code above does't work... I just wanted to illustrate what I'm trying to do.</p>
