# Usage: cd /usr/src/contrib/jemalloc
# ./FREEBSD-upgrade <command> [args]
#
# At least the following ports are required when importing jemalloc:
# - devel/autoconf
# - devel/git
# - devel/gmake
# - textproc/docbook-xsl
# - textproc/libxslt
#
# The normal workflow for importing a new release is:
#
# cd /usr/src/contrib/jemalloc
#
# Merge local changes that were made since the previous import:
#
# ./FREEBSD-upgrade merge-changes
# ./FREEBSD-upgrade rediff
#
# Extract latest jemalloc release.
#
# ./FREEBSD-upgrade extract
#
# Fix patch conflicts as necessary, then regenerate diffs to update line
# offsets:
#
# ./FREEBSD-upgrade rediff
# ./FREEBSD-upgrade extract
#
# Do multiple buildworld/installworld rounds. If problems arise and patches
# are needed, edit the code in ${work} as necessary, then:
#
# ./FREEBSD-upgrade rediff
# ./FREEBSD-upgrade extract
#
# The rediff/extract order is important because rediff saves the local
# changes, then extract blows away the work tree and re-creates it with the
# diffs applied.
#
# Finally, to clean up:
#
# ./FREEBSD-upgrade clean
