title: How can I decode the boost library naming?
body: <p>I tried to find out that <code>gd</code> means in boost library name and I only found two other people looking for the same thing.</p>
  <p>I suppose it should be a place where this is clearly documented and I would like to find it.</p>
  <ul>
  <li><code>mt</code> - multitheaded, get it with <code>bjam threading=multi</code></li>
  <li><code>s</code> - <code>bjam runtime-link=static</code></li>
  <li><code>g</code> - using debug versions of the standard and runtime support libraries. <strong>what bjam switch???</strong></li>
  <li><code>d</code> - debug <code>bjam variant=debug</code></li>
  </ul>
  <h1>Update</h1>
  <p>How do I control what <code>bjam</code> switches controls the above variants? In fact the only one that I wasn't able to identify is the <code>g</code>.</p>
