// To place breadcrumbs in your page, save this

// BEGIN BASIC CUSTOMIZATION
// Starting Point: 1 = domain, 2 = 1st directory, 3 = 2nd directory, etc.
// Must be specified as an integer; no floating point numbers.
// ***Note***: If the starting number is greater than the number of
// directories you have, the URL will be undefined.
var startPoint = 1; // idea from Hassan Schroeder
// Separator: set the character(s) that will be used to
// separate each of the breadcrumb links.
// Set the space in between each link by
// specifying a number of non-breaking spaces ( ).
// The default separator is a "greater than(>)" symbol (>).
var sep = " | "
// Starting Name: setting startName to "domain" will
// use the full domain name (www.yourdomain.com).
// Any other text will be used literally.
// E.g., specifying "Home" will use "Home" as the first
// link in the chain.
// ***Note***: if startPoint is greater than 1, it will start
// the chain at a point beyond the domain. startName will
// be used for the name of the first link, regardless of where it
// starts.

// uppercase is set to yes, the first character
// in each of the directory names will be capitalized.

// name will be capitalized for each directory.

// URL that ends in a directory name? E.g., if the URL
// is http://www.mydomain.com/start/, do you want the
// script to write the name of the directory or the
// title of the default document in this directory?
// You have 2 choices: directory or title.
