 /**
  * Format for Discourse Tool
- * <p/>
+ * <p>
  * Original code by <A HREF="http://usuarios.iponet.es/imoreta">owd</A>.
  * Revised and updated for revision 0108 by Ben Fry (10 March 2006).
  * This code may later be moved to its own 'Tool' plugin, but is included
  * with release 0108+ while features for the "Tools" menu are in testing.
- * <p/>
+ * <p>
  * Updated for 0122 to simply copy the code directly to the clipboard,
  * rather than opening a new window.
- * <p/>
+ * <p>
  * Updated for 0144 to only format the selected lines.
- * <p/>
+ * <p>
  * Updated for 1.5.8 - Simplification, using RSyntaxTextArea TokenImpl formatter (08 dec 2014 - Ricardo JL Rufino)
- * <p/>
+ * <p>
  * Notes from the original source:
  * Discourse.java This is a dirty-mix source.
  * NOTE that: No macs and no keyboard. Unreliable source.
