This package allows PHP applications to interact with the Systemd Notification daemon.
It sends feedback to the Systemd daemon about the runtime status
of a service.
A service periodically sends watchdog (heartbeat) events to
Systemd's notification daemon. When the watchdog (heartbeat) events
stop, Systemd knows the service has a problem and can restart it.
This package provides classes to interact with the notification service by sending heartbeats.
