     * ---------------------

     * (InteractiveTools.com) release a new official version, it's less
     * likely that you will have problems upgrading HTMLArea.
     *
     * Example on how to add a custom button when you construct the HTMLArea:
     *
     *   var editor = new HTMLArea("your_text_area_id");
     *   var cfg = editor.config; // this is the default configuration
     *   cfg.btnList["my-hilite"] =
     *	[ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action
     *	  "Highlight selection", // tooltip
     *	  "my_hilite.gif", // image
     *	  false // disabled in text mode
     *	];
     *   cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
     *
     * An alternate (also more convenient and recommended) way to
     * accomplish this is to use the registerButton function below.
