# This script is a gem from the Wordpress 2.0.2-2.0.3 upgrade that
# calculates the URL a given path will have on scripts. It does three
# things:
#   1. Resolves all symbolic links
#   2. Splits the path on web_scripts to home and path
#   3. Use home to ldap search for the name of the locker we're serving
#   4. Build the URL from the kaboodle
