# Purpose: This script will iterate through each MXD in a folder and report information about each
#          map document, it's data frames and layers.  The script is intended to run from a script
#          tool that requires two input parameters:
#               1) folder containing MXDs,
#               2) an output text file.
#
#          The resulting text file will automatically open.
