// Nifty Breadcrumbs Script //
//////////////////////////////////////////////////////////////////////////////
//
// This is a neat little script that takes your site's file/folder structure
// and converts it into breadcrumbs. As an added bonus, it forces you to
// create a structure that is optimal for search engines to index and rank!

// [INSERT YOUR NAME AND BRIEF DESCRIPTION OF YOUR CONTRIBUTION HERE]
//
// INSTRUCTIONS:
//
// 1. Create your site structure using folders and files with useful names.
// Use underscores to signify spaces when naming everything.
//
// Example: http://www.squid.com/My_Pet_Squid/Meet_Rocky.html shows good
// name choices to describe an area of content and the contents of a page.
//
// Alternatively, you can setup mod_rewrite to create friendly URLs such
// as the one above.
//
// Every folder *must* have a default document in it (such as index.html
// or default.asp or whatever your host specifies). You can also use
// 301/302 redirection to push the folder root to one of the pages within
// that folder. This will replace an index page, if you don't wish to
// have one.
//
// 1a. If you want to use something other than underscores for spaces (such
// as hyphens), you can make edits to the actual script to recognize
// your preference. A set of prewritten code lines have been inserted
// below and commented out. Feel free to use them, or to create your
// own based on them.
//
// 2. Fill in the settings for the variables in the next section of this
// script. They should be pretty self-explanatory.
//
// 3. Add the following to your site wherever you want your breadcrumbs
// to appear (change the path to point to wherever you put this script):
//
// <div id="breadcrumbs"></div>
// <script type="text/javascript" src="path/to/breadcrumbs.js"></script>
