		// ------------- The Script --------------

		// First, create a variable to hold the browser type.

		var brsr = navigator.appName

		// Next, create a function that tells the browser which
		// style-sheet to import.  Netscape is the only browser
		// which currently has its own style-sheet, but this
		// architecture would allow any browser to have one.  
		// You could also parse the version, if necessary.

			} else {
				whichStyle = "<link rel='STYLESHEET' type='text/css' href='../style/lhief.css'>"
				document.write(whichStyle);
			}	

		}

		// Finally, call the function.

		checkWhich()


		// ------------- End Script --------------

		// Note, browsers with JavaScript disabled will not
		// import any style-sheet whatsoever.
