# upstream PR https://github.com/OpenPrinting/cups/pull/518
# Implementation: we need to get a scope for /admin location, which starts with <Location /admin>
# and ends with the first </Location>, so once we find the opening tag via sed, we implement a sed loop,
# which saves all lines which don't match the ending tag into pattern space, and once there is
# the ending tag, print the whole pattern buffer. The buffer is checked for AuthType and Require directives.
# If they already exist, we don't add anything. cupsd.conf.rpmsave is created as a backup.
