// This snippet was designed to show the

// is NOT necessarily the path the user
// took to arrive at a given page. Based on
// PageTrail snippet by: Bill Wilson.

// Configuration Settings

   // $maxCrumbs [number]
   // Max number of elements to have in a path.
   // 100 is an arbitrary high number.
   // If you make it smaller, like say 2, but you
   // you are 5 levels deep, it will appear as:
   // Home > ... > Level 4 > Level 5
   // It should be noted that "Home" and the current
   // page do not count. Each of these are configured
   // separately.

   // $pathThruUnPub [ true | false ]
   // When you path includes an unpublished folder, setting this to 
   // true will show all documents in path EXCEPT the unpublished.
   // Example path (unpublished in caps)
   // home > news > CURRENT > SPORTS > skiiing > article
   // $pathThruUnPub = true would give you this:
   // home > news > skiiing > article

   // with a link to home? Some would not because
   // a home link is usually found in the site logo
   // or elsewhere in the navigation scheme.

   // home page.
