utils.AtInterruption(func() {

db.Close()
log.Printf("Shutting down New Relic application.")
nrl.Shutdown(5 * time.Second)
})
Logging and terminating the process on error
EndAsErr will log the error message and terminate the process if err is not nil
func main() {
di := setup.Start()
err := server.Start(di)
utils.EndAsErr(err, "Could not start the server.", di.Log.InfoWriter(), di.Log.ErrorWriter())
}
