relevanssi_the_excerpt()
Prints out the post excerpt, without applying any filters. Only works in the Loop.
Source: /lib/utils.php
Usage
Uses the global $post object and prints out the $post->post_excerpt inside <p> tags. If the post is password protected (according to post_password_required()), a note about that is printed out.
The main purpose for this function compared to the_excerpt() is that this function does not apply any the_excerpt filters on the excerpt.
