"""zdaemon -- run an application as a daemon.

Usage: python zdaemon.py [zdaemon-options] program [program-arguments]
Or:    python zdaemon.py -c [command]

Options:
  -b SECONDS -- set backoff limit to SECONDS (default 10; see below)
  -c -- client mode, to sends a command to the daemon manager; see below
  -d -- run as a proper daemon; fork a background process, close files etc.
  -f -- run forever (by default, exit when the backoff limit is exceeded)
  -h -- print usage message and exit
  -s SOCKET -- Unix socket name for client communication (default "zdsock")
  -u USER -- run as this user (or numeric uid)
  -x LIST -- list of fatal exit codes (default "0,2"; use "" to disable)
  -z DIRECTORY -- directory to chdir into when using -d; default "/"
  program [program-arguments] -- an arbitrary application to run

Client mode options:
  -s SOCKET -- socket name (a Unix pathname) for client communication
  [command] -- the command to send to the daemon manager (default "status")

Client commands are:
  help -- return command help
  status -- report application status (this is the default command)
  kill [signal] -- send a signal to the application
                   (default signal is SIGTERM)
  start -- start the application if not already running
  stop -- stop the application if running; daemon manager keeps running
  restart -- stop followed by start
  exit -- stop the application and exit

This daemon manager has two purposes: it restarts the application when
it dies, and (when requested to do so with the -d option) it runs the
application in the background, detached from the foreground tty
session that started it (if any).
