# 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 them pipe them into pkgchk.  For
# each file which already exists and whose contents do not match the size or
# checksum saved in the package database, we get (^ = start of line):
#
#	^ERROR: /etc/init.d/somefile
#	^    file size <104780> expected <181> actual
# 	^    file cksum <56515> expected <14331> actual
#
# We grep for ERROR: followed by a single non-whitespace token, then strip
# the leading '^ERROR: ', leaving us a name of a modified file that we
# capture in the 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.
