#
# HOW TO UPDATE THE ZONEINFO DATA
#
# Import the new sources to the vendor branch:
#
# $ cd ~/freebsd/src
# $ git worktree add ../tzdata vendor/tzdata
# $ pushd ../tzdata
# $ tar -xvf ../tzdata-latest.tar.gz
#   (check with "git status" and "git diff" if it all makes sense)
# $ git add -A
# $ git commit -m "Import tzdata 20XXX"
# $ git tag -a -m "Tag import of tzdata 20XXX" vendor/tzdata/tzdata20XXX
# $ git push --follow-tags freebsd vendor/tzdata
# $ popd
#
# Merge-from-vendor
#
# $ git subtree merge -P contrib/tzdata vendor/tzdata
#   (write a meaningful commit message)
# $ git push freebsd HEAD:main
#
# MFC
#
# $ git checkout -b freebsd/stable/12 stable-12
# $ git cherry-pick -x [hash of merge commit to main] -m 1 --edit
#   (write a meaningful commit message)
# $ git push freebsd HEAD:stable/12
