Checks URLs for updates and prints human-readable diffs to the console or to a logfile. Maintains state between runs.
Requires go 1.16. If you don't want to install it, then use run_in_docker.sh
instead of go run watchurl.go.
On macOS, watchurl shows desktop notifications when a site is updated. To
disable this behavior, pass --nomacos-notify.
(Notifications don't work when running in Docker.)
