/* getJS_menu_tpl.js
 * Get javascript for drop-down menus according to browser.
 *  - MSIE handles pixel calculation from top/side of page 
 *     different than other browsers.
 *  - We're defaulting to the most common (MSIE browsers)
 *      and changing to different template if it's another OS/browser.
 *  - Write the javascript src code directly into the header of the html page.
 *  - Write the javascript src according to the level of subdirectory
 *     is the calling page, (rather than leading slash '/lib/js/blah.js')
 *     so that this can be used on a standalone machine without webserver.
 *  08 mar 2005 - modfied for javascript location; firefox.
 *  01 jan 2005 - tightened up, and added better logic
 *                in case browser not named!
 *  13 dec 2003 - wrote for presscluboftibet.
