# METALOG MANIPULATION TARGETS
#
# METALOG is the name of a metadata log file, and is set in <bsd.own.mk>
# if MKUNPRIVED is not "no".
#
# METALOG.unpriv is a command line option passed to various scripts;
# it is either blank or "-M ${METALOG}.sanitised", depending on the
# MKUNPRIVED flag.
#
# The sanitise_METALOG target creates METALOG.sanitised from METALOG,
# without modifying METALOG itself.  This is used near the end of
# a build, after build products have been installed in DESTDIR
# and corresponding lines have been added to METALOG, but before
# METALOG.sanitised is used in the creation of sets in RELEASEDIR.
# For update builds, METALOG.sanitised has duplicates merged (keeping
# only the last of multiple entries for the same item), but for clean
# builds it's an error if a file or directory name appears twice.
# METALOG.sanitised is always sorted and has timestamps removed.
#
# The clean_METALOG target either deletes METALOG, or replaces METALOG with
# a sanitised version of itself, depending on the MKUPDATE flag, and
# deletes old METALOG.* files.  This is intended to be used at the start
# of a build, to ensure that repeated MKUPDATE builds do not cause
# unbounded growth of METALOG.
