title: Where is ${basedir} located, using NLog?
body: <p>Unless I'm totally missing it, I'm under the impression that the <a href="http://nlog-project.org/" rel="noreferrer">NLog documentation</a> uses <code>${basedir}</code> in its examples, without explaining what its location is supposed to be.</p>
  
  <p>Where can I find information that lists all possible options with a meaningful description?</p>
  
  <p>I have this configuration defined:</p>
  
  <pre><code>&lt;nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" throwExceptions="true"&gt;
    &lt;targets&gt;
      &lt;target name="file" xsi:type="File"
                  layout="${longdate} ${logger} ${message}"
                  fileName="${basedir}/logs/${shortdate}.txt"
                  keepFileOpen="false"
                  encoding="iso-8859-2" /&gt;
    &lt;/targets&gt;
    &lt;rules&gt;
      &lt;logger name="*" minlevel="Debug" writeTo="file" /&gt;
    &lt;/rules&gt;
  &lt;/nlog&gt;
  </code></pre>
  
  <p>It works as far as I can tell, but I haven't got a clue where it logs anything at.</p>
