/**

* Breadcrumb Trail - A breadcrumb menu script for WordPress.

|

|
|
* Breadcrumb Trail is a script for showing a breadcrumb trail for any type of page. It tries to
|
||
|
|
* anticipate any type of structure and display the best possible trail that matches your site's
|
||
|
|
* permalink structure. While not perfect, it attempts to fill in the gaps left by many other
|
||
|
|
* breadcrumb scripts.
