//	This script generates an optimal frameset for different browsers.
//	The resulting frameset is exactly (Microsoft) or close to (Netscape) the following:
//
//	<frameset rows='105,*' framespacing=0 frameborder='NO' BORDER='0'>
//		<frame src='[your top frame source as defined in index.html]' frameborder=0 name='navigation_top' marginwidth=0 marginheight=0 scrolling='no'>
//		<frame src='[your content frame source as defined in index.html]' name='content' frameborder=0 marginwidth=0 marginheight=0 noresize scrolling='auto'>
//		<frame src='[your bottom frame source as defined in index.html]' frameborder=0 name='navigation_bottom' marginwidth=0 marginheight=0 scrolling='no'>
//	</frameset>
//
//	NOTE:
//
//	top frame's name is "navigation_top" 
//	content frame's name is "content" 
//	bottom frame's name is "navigation_bottom"
