title: \startuml command in doxygen with PLANTUML_JAR_PATH
body: <p>I am using plantuml to generate to UML figures and have a problem about the comments style.</p>
  
  <p>Steps to reproduce my problem:</p>
  
  <p>I create a file called mainpage.dox and write these contents:</p>
  
  <pre><code>/** \mainpage Sender class
   * Sender class. Can be used to send a command to the server.
   *  The receiver will acknowledge the command by calling Ack().
   *  \startuml
   *    Sender-&gt;Receiver  : Command()
   *    Sender&lt;--Receiver : Ack()
   *  \enduml
   */
  </code></pre>
  
  <p>Then, I create doxyfile to set output optimized java or C#, has_dot and PLANTUML_JAR_PATH. The UML figure could be generated after running doxygen. </p>
  
  <p>However, there is no any contents of mainpage and warning message when I change comment style into C#:</p>
  
  <pre><code>/// \mainpage Sender class
  /// Sender class. Can be used to send a command to the server.
  /// The receiver will acknowledge the command by calling Ack().
  /// \startuml
  ///   Sender-&gt;Receiver  : Command()
  ///   Sender&lt;--Receiver : Ack()
  /// \enduml
  ///
  </code></pre>
  
  <p>But the main page is generated (Show the text below) when I remove the uml comments</p>
  
  <pre><code>/// \mainpage Sender class
  /// Sender class. Can be used to send a command to the server.
  /// The receiver will acknowledge the command by calling Ack().
  </code></pre>
  
  <p>Does \startuml have to use C style comments? Thanks for any suggestion.</p>
  
  <p>This is my DoxyFile: <a href="http://pastebin.com/hjEFz8b0" rel="nofollow">http://pastebin.com/hjEFz8b0</a></p>
  
  <p>EDIT: </p>
  
  <p>I just tested again with another style of comment. \startuml is working with this style</p>
  
  <pre><code>/*! \mainpage Sender class
  Sender class. Can be used to send a command to the server.
  The receiver will acknowledge the command by calling Ack().
  \startuml
  Sender-&gt;Receiver  : Command()
  Sender&lt;--Receiver : Ack()
  \enduml
  */
  </code></pre>
