//Configuration info
//The following variables need to be set in the top of each page before this script is included:

var section = "";
var unique_style = false;

//The two lines above can be uncommented if the site isn't going to require the overriding of any section names or unique styles.
//The following needs to be added into the body tag of your HTML page:

//onload="set_styles();"

//Links need the id setting to the following, if they are to be controlled by this script:
//nb.  Section name is the toplevel directory that the page resides in, unless overriden.  home is the homepage.

//NB. Standard Macromedia mouseovers can be used for image hovers.

//image links: id="img_sectionname"
//header text links: link_sectionname
//footer text links: footer_sectionname

//The following styles need to be included in your stylesheet (you can change the properties to whatever you like:

//	.navselected, .navselected:hover {
//	color:#cccccc;
//	text-decoration:none;
//	cursor: default;
//	font-weight : bold;
//	}

//	.navfootselected, .navfootselected:hover {
//	color:#cccccc;
//	text-decoration:none;
//	cursor: default;
//	font-weight : bold;
//	}

//The following three variables need to be set:

var image_path = "/images/template/";
var image_extension = "gif";
var styles_path = "/script_library/";

//Don't edit below here
