# This script takes a single argument, the name of a file (normally expected to
# be 'build_image'), which should be a shell script. It then creates a new
# output file, named <input_file>.edited, and it copies each line from the
# input file to the output file. If the line from the input file contains the
# string 'eclean', it prepends a '#' to the line before copying it to the
# output file, in effect commenting out any lines that contain 'eclean'.
