title: How to set dependency as runtime in SBT (to mimic runtime scope in Maven)?
body: <p>I have a dependency in <code>runtime</code> scope in a Maven project:</p>
  
  <pre><code>&lt;dependency&gt;
    &lt;groupId&gt;org.docbook&lt;/groupId&gt;
    &lt;artifactId&gt;docbook-xml&lt;/artifactId&gt;
    &lt;version&gt;4.4&lt;/version&gt;
    &lt;scope&gt;runtime&lt;/scope&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>How can I express this in SBT?</p>
