# Before we begin installing new files, we need to save the existing files
# if the administrator has modified them since their original installation.
# To do this, we find 'e' and 'l' entries in the pkgmap, convert their
# relative "etc/" prefix to /etc, and pipe these files to a while loop.
# For every file that is piped, call pkgchk(1M) with '-q' and '-p' options
# with the package name to which this file belongs. For each file which
# already exists and whose contents do not match the size or checksum
# saved in the package database, pkgchk(1M) returns an error code which
# is not '0'. In such a case, capture the name of the file into
# MODIFIED_AFTER_INSTALLED. variable. This variable is written to the file
# provided as an argument to the script, in the form of an environment
# variable setting. Said file later gets sourced by the pkgadd command for
# use in our class action script.
