examples <<~DOC
Wire up a notification from a service resource to stop and start the service with a 60 second delay.
```
service "crude" do
action [ :enable, :start ]
end
chef_sleep "60" do
action :nothing
end
# Example code for a hypothetical badly behaved service that requires
# 60 seconds between a stop and start in order to restart the service
# (due to race conditions, bleeding connections down, resources that only
# slowly unlock in the background, or other poor software behaviors that
# are sometimes encountered).
