# Purpose: This script will perform a search and replace on page layout text
#          elements. There are options to match case and/or find exact matches.
#          This script is intended to run as a scrip tool and requires three
#          parameters (and two optional parameters):
#               1) Input map document,
#               2) Find string,
#               3) Replace string,
#               4) Match case,
#               5) Match entire string.
