Makefile

# Because this repository uses multiple `go.mod` files, it is helpful
# to have top-level make rules to run `go test`, `go build`, and `go
# mod tidy` on every module.  Use `make all` to ensure that all Go
# code builds, passes tests, and has update-to-date `go.mod`
# dependencies.
#
# The `make fmt` rule is not included in `all`, to allow manually
# formatting the Go sources.
