4# HOW TO UPDATE THE ZONEINFO DATA
5#
6# Import the new sources to the vendor branch:
7#
8# $ cd ~/freebsd/src
9# $ git worktree add ../tzdata vendor/tzdata
10# $ pushd ../tzdata
11# $ tar -xvf ../tzdata-latest.tar.gz
12#   (check with "git status" and "git diff" if it all makes sense)
13# $ git add -A
14# $ git commit -m "Import tzdata 20XXX"
15# $ git tag -a -m "Tag import of tzdata 20XXX" vendor/tzdata/tzdata20XXX
16# $ git push --follow-tags freebsd vendor/tzdata
17# $ popd
18#
19# Merge-from-vendor
20#
21# $ git subtree merge -P contrib/tzdata vendor/tzdata
22#   (write a meaningful commit message)
23# $ git push freebsd HEAD:main
24#
25# MFC
26#
27# $ git checkout -b freebsd/stable/12 stable-12
28# $ git cherry-pick -x [hash of merge commit to main] -m 1 --edit
29#   (write a meaningful commit message)
30# $ git push freebsd HEAD:stable/12
