== Description ==

This script is used to start a job server manually for running
ensemble-based jobs in a parallel distributed computing environment.
The utilities <docmark>ensmin.pl</docmark>, <docmark>enslatsim.pl</docmark>,
<docmark>ensrun.pl</docmark> may then be used as clients by giving the
server host, port and ID through their -rserv option. 
Starting the job server manually is most useful when remote
execution via rsh is not possible in a distributed
environment. Otherwise the -hosts option for the ensemble
utilities is a more convenient way since it will start the server
automatically and submit clients via rsh. 
This utility requires the tag name of the ensemble structures as argument.
Additional options are available to select the ensemble directory (-dir),
the desired runs for which a job list should be created (-runs),
the property that is used for identifying which jobs need to be run (-use,
by default: etot), and to request a log file with -log. 
The script writes to standard output the host name, port, and server ID in the
format expected by the client -rserv option. Since the script waits for the
server to exit after spawning a new process for the server it is recommended
to start the script in the background with &.
