your-service.conf

#
# Put your-service.conf in /etc/init/your-service.conf
#
# Then tell upstart about your new service:
# $ sudo initctl reload-configuration
#
# Then these commands all work as expected:
# $ sudo start your-service
# $ sudo stop your-service
# $ sudo status your-service
# $ sudo restart your-service
