2# $FreeBSD$
3#
4# Usage: cd /usr/src/contrib/jemalloc
5#        ./FREEBSD-upgrade <command> [args]
6#
7# At least the following ports are required when importing jemalloc:
8# - devel/autoconf
9# - devel/git
10# - devel/gmake
11# - textproc/docbook-xsl
12#
13# The normal workflow for importing a new release is:
14#
15#   cd /usr/src/contrib/jemalloc
16#
17# Merge local changes that were made since the previous import:
18#
19#   ./FREEBSD-upgrade merge-changes
20#   ./FREEBSD-upgrade rediff
21#
22# Extract latest jemalloc release.
23#
24#   ./FREEBSD-upgrade extract
25#
26# Fix patch conflicts as necessary, then regenerate diffs to update line
27# offsets:
28#
29#   ./FREEBSD-upgrade rediff
30#   ./FREEBSD-upgrade extract
31#
32# Do multiple buildworld/installworld rounds.  If problems arise and patches
33# are needed, edit the code in ${work} as necessary, then:
34#
35#   ./FREEBSD-upgrade rediff
36#   ./FREEBSD-upgrade extract
37#
38# The rediff/extract order is important because rediff saves the local
39# changes, then extract blows away the work tree and re-creates it with the
40# diffs applied.
41#
42# Finally, to clean up:
43#
44#  ./FREEBSD-upgrade clean
45
