+** : : : : : :  How to use the Show Help  : : : : : :
+** For each interesting page element you can put the
+** attribute help. The help attribute can be any string
+** text (scaped to not distroy the html) or some html id.
+** The help for each element will be showed automaticaly
+** when the mouse is over that. Yeah... we can turn on
+** this help system calling the function showMouseHelpOn()
+** and turn off calling the function showMouseHelpOff().
+**
+** Examples:
+**
+** <a href="..." help="this is a link">my link</a>
+**
+** <form help="#myLongHelp"> ... </form>
+** <div id="myLongHelp" style="display:none">
+**   This is a <b>loooong</b> help. <p/>
+**   You can put <code>HTML</code> here too!
+** </div>
+**
+** You need to put the style="display:none" on the long
+** help container to it's text do not noise the web page.
+**
+** If the mouse pointed element do not have a help,
+** each one of this parents will be visited to find
+** the help. If no one has a help the help box turn
+** to non visible.
