// Package timer provides an example to set up ScheduledTaskProps with re-configurable schedule and sending destination.
//
// The configuration struct, timerConfig, implements both sarah.ScheduledConfig and sarah.DestinatedConfig interface.
// The configuration values are read from timer.yaml and the command is rebuilt when the configuration file is updated.
