title: HelpVerbOption is not working - Command Line Parser C#
body: <p>I have a class:</p>
  
  <pre><code>class Options
  {
      // Remainder omitted (verb1, verb2, verb3)
      [HelpVerbOption]
      public string GetUsage(string verb)
      {
          return HelpText.AutoBuild(this, verb);
      }
  }
  </code></pre>
  
  <p>The <a href="https://github.com/gsscoder/commandline/wiki/Verb-Commands" rel="nofollow noreferrer">docs</a> say: </p>
  
  <blockquote>
    <p>[...] The parser will pass null to master class GetUsage(string) also if
    the user requested the help index with:</p>
    
    <p>$ git help </p>
    
    <p>or the verb command if the user requested explicitly
    instructions on how to use a particular verb:</p>
    
    <p>$ git help commit</p>
    
    <p>[...]</p>
  </blockquote>
  
  <p>Then, I typed <code>MyApp.exe help verb1</code>, but I could see only the base help (that looked like I typed the wrong verb, or <code>help</code> verb, or something). Rather, I expect it to show the help message related to specified verb. Why isn't it working properly? </p>
