# 
#     scheduler_daemon run           # start the daemon and stay on top
#     scheduler_daemon start         # start the daemon and stay on top
#     scheduler_daemon stop          # stop all instances of the application
#     scheduler_daemon restart       # stop all instances and restart them afterwards
#
# options can be passed to the scheduler like so:
#
#     scheduler_daemon start -- --except=session_cleaner
#
# options can be passed to the daemon:
#
#     scheduler_daemon start --dir=/my/rails/root/
