# When updating this package, my process is:
#  - run `GOPATH=$PWD go get -d -u github.com/hlandau/acme/cmd/acmetool`
#  - run this one-liner: find src -name .git | while read -r dir; do (cd $dir/.. && git log --pretty="$dir %H $(git describe --tags --always) %ci" -n1); done|sed -r 's|src/(.*)/\.git |\1 |'|while read -r dir hash desc date; do printf '%s %s %s %s\n' "$(date --rfc-3339=seconds -u --date="$date")" "$dir" "$desc" "$hash"; done|column -t|sort -n
#    * verify that no timestamps are newer than that of github.com/hlandau/acme
#      > roll back anything that is newer (be careful of commits that weren't yet merged!)
#    * anything that has changed since PKGBUILD, verify that the license is the same
