NAME
       start_server - a superdaemon for hot-deploying server programs

SYNOPSIS
         start_server [options] -- server-prog server-arg1 server-arg2 ...

         # start Plack using Starlet listening at TCP port 8000
         start_server --port=8000 -- plackup -s Starlet --max-workers=100 index.psgi

DESCRIPTION
       This script is a frontend of Server::Starter.  For more information
       please refer to the documentation of the module.

OPTIONS
   --port=(port|host:port|port=fd|host:port=fd)
       TCP port to listen to (if omitted, will not bind to any ports)

       If host is not specified, then the program will bind to the default
       address of IPv4 ("0.0.0.0").  Square brackets should be used to specify
       an IPv6 address (e.g. --port=[::1]:8080)

       If fd is specified, then start_server allocates the socket at the given
       number.

   --path=path
       path at where to listen using unix socket (optional)

   --dir=path
       working directory, start_server do chdir to before exec (optional)

   --interval=seconds
       minimum interval to respawn the server program (default: 1)

   --signal-on-hup=SIGNAL
       name of the signal to be sent to the server process when start_server
       receives a SIGHUP (default: SIGTERM). If you use this option, be sure
       to also use "--signal-on-term" below.

   --signal-on-term=SIGNAL
       name of the signal to be sent to the server process when start_server
       receives a SIGTERM (default: SIGTERM)

   --pid-file=filename
       if set, writes the process id of the start_server process to the file

   --status-file=filename
       if set, writes the status of the server process(es) to the file

   --envdir=ENVDIR
       directory that contains environment variables to the server processes.
       It is intended for use with "envdir" in "daemontools".  This can be
       overwritten by environment variable "ENVDIR".

   --log-file=file
   --log-file="| cmd args..."
       if set, redirects STDOUT and STDERR to given file or command

   --daemonize
       deamonizes the server (by doing fork,setsid,fork).  Must be used
       together with "--log-file".

   --enable-auto-restart
       enables automatic restart by time.  This can be overwritten by
       environment variable "ENABLE_AUTO_RESTART".

   --auto-restart-interval=seconds
       automatic restart interval (default 360). It is used with
       "--enable-auto-restart" option.  This can be overwritten by environment
       variable "AUTO_RESTART_INTERVAL".

   --kill-old-delay=seconds
       time to suspend to send a signal to the old worker. The default value
       is 5 when "--enable-auto-restart" is set, 0 otherwise.  This can be
       overwritten by environment variable "KILL_OLD_DELAY".

   --backlog=size
       specifies a listen backlog parameter, whose default is SOMAXCONN
       (usually 128 on Linux). While SOMAXCONN is enough for most loads, large
       backlog is required for heavy loads.

   --restart
       this is a wrapper command that reads the pid of the start_server
       process from --pid-file, sends SIGHUP to the process and waits until
       the server(s) of the older generation(s) die by monitoring the contents
       of the --status-file

   --stop
       this is a wrapper command that reads the pid of the start_server
       process from --pid-file, sends SIGTERM to the process.

   --help
       prints this help

   --version
       prints the version number
