DESCRIPTION

       estmaster  is  an  aggregation of sub commands.  The name of a sub command is specified by
       the first argument.  Other arguments are  parsed  according  to  each  sub  command.   The
       argument rootdir specifies the server root directory which contains configuration file and
       so on.

       estmaster init [-ex] rootdir
              Create the server root directory.
              If -ex is specified, some users and some nodes are set for  example.   By  default,
              only a super user whose name and password are both "admin" is set.

       estmaster start [-bg] [-ro] [-st] rootdir
              Start the node master.
              If -bg is specified, the server runs in background as a daemon process.
              If  -ro  is  specified,  the  server  runs  in  read-only  mode  regardless  of the
              configuration.
              If -st is specified, the server runs in single thread mode.

       estmaster stop rootdir
              Stop the running node master.

       estmaster unittest rootdir
              Perform unit tests.

       estmaster crypt key [hash]
              Output an encrypted string of a string.
              key specifies a target string.
              If hash is specified, it checks whether the key and the hash matches.

       All sub commands return 0 if the operation is success, else  return  1.   A  running  node
       master  finishes  with  closing  the  database  when  it  catches the signal 1 (SIGHUP), 2
       (SIGINT), 3 (SIGQUIT), or 15 (SIGTERM).  Moreover, when a node master running as a  daemon
       catches  the  signal  1  (SIGHUP),  the  process is re-start and re-read the configuration
       files.

       A running node server should be finished by valid means by command line  or  via  network.
       Otherwise, the index may be broken.
