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# - textproc/libxslt
13#
14# The normal workflow for importing a new release is:
15#
16#   cd /usr/src/contrib/jemalloc
17#
18# Merge local changes that were made since the previous import:
19#
20#   ./FREEBSD-upgrade merge-changes
21#   ./FREEBSD-upgrade rediff
22#
23# Extract latest jemalloc release.
24#
25#   ./FREEBSD-upgrade extract <rev>
26#
27# Fix patch conflicts as necessary, then regenerate diffs to update line
28# offsets:
29#
30#   ./FREEBSD-upgrade rediff
31#   ./FREEBSD-upgrade extract <rev>
32#
33# Do multiple buildworld/installworld rounds.  If problems arise and patches
34# are needed, edit the code in ${work} as necessary, then:
35#
36#   ./FREEBSD-upgrade rediff
37#   ./FREEBSD-upgrade extract <rev>
38#
39# The rediff/extract order is important because rediff saves the local
40# changes, then extract blows away the work tree and re-creates it with the
41# diffs applied.
42#
43# Finally, to clean up:
44#
45#  ./FREEBSD-upgrade clean
