\begin{Description}
  \item[\Opt{-p}, \OptSArg{--coord-port}{port} (environment variable DMTCP\_COORD\_PORT)]
    Port to listen on (default: 7779)

  \item[\OptSArg{--port-file}{filename}]
    File to write listener port number.
    (Useful with \Opt{--coord-port 0}, which is used to assign a random port)

  \item[\OptSArg{--ckptdir}{path} (environment variable DMTCP\_CHECKPOINT\_DIR)]
    Directory to store dmtcp\_restart\_script.sh (default: ./)

  \item[\OptSArg{--tmpdir}{path} (environment variable DMTCP\_TMPDIR)]
    Directory to store temporary files (default: env var TMDPIR or \File{/tmp})

  \item[\Opt{--exit-on-last}] Exit automatically when last client disconnects

  \item[\Opt{--exit-after-ckpt}] Exit automatically after checkpoint is created

  \item[\Opt{--daemon}]
    Run silently in the background after detaching from the parent process.

  \item[\Opt{-i}, \OptSArg{--interval}{<val>} (environment variable DMTCP\_CHECKPOINT\_INTERVAL)]
    Time in seconds between automatic checkpoints (default: 0, disabled)

  \item[\Opt{-q}, \Opt{--quiet}] Skip copyright notice.

  \item[\Opt{--help}] Print this message and exit.

  \item[\Opt{--version}] Print version information and exit.
