   Helpicon elements add a help icon at the current location.
   Example:

        General Help
      </helpicon>
   
   In this example will generate a help icon to the Help.hlp url with a
   description of 'General Help'. The description is not required and if
   left out (Example: <helpicon file="Help" /> only the icon will be
   added.)
