//////////////////////////////////////////////////////////////////////////////
// 
// 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!

//
// VERSIONS:
//
// 2.0
//     - COMPLETE overhaul of markup, from the ground up!
//     - Removed all requirements for a file extension to be set.
//     - Folder roots have been eliminated.  Now, when visitors step up the
//       breadcrumbs, they are taken to the parent folder via "../" only.
//     - Removed the script portion that parses the jumplink octothorpe. It
//       wasn't really doing anything all that useful.
//     - Script now functions at any folder level, not just the domain root.
//     - Updated instructions.  The script is now much easier to use!
//
// 1.1
//     - A little code cleanup.  Double quotes replaced with single quotes,
//       escaped characters unescaped.
//     - Word separators (underscore, hyphen, etc.) are now user-declared.
//     - Custom word replacement now available.  Use your own words in place
//       of your folder/file names.
// 1.0
//     - Original breadcrumbs script released.
//
// INSTRUCTIONS:
//
// 1.  Create your site structure using folders and files with useful names.
//     You may choose any character you'd like to replace spaces in your
//     URLs.  I recommend using underscores (as in the example below), but
//     this script will allow you to specify any single character you'd like
//     to be the replacement for spaces.  If you use something other than
//     underscores, you will need to make a change in the variables section.
//
//     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 via your .htaccess file to
//     create friendly URLs such as the one above.
//
// 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>

//////////////////////////////////////////////////////////////////////////////
// Change the following variables as instructed                             //

// Want to replace any folder names with custom names of your own?  Create
