# Script to start the FXC repeater.
# (Note: This script is not necessary if the repeater and 
# server run on the same host. In this case the repeater
# can be started directly with the run-server command
# by adding the parameter "-repeaterport [port]" to the
# serverManager arguments. The client uses the ip addresses 
# in Hosts.txt to route the message to the server).
#
# This script starts a repeater on a Windows or Linux machine that
# does not have or support a server. The repeater reads messages 
# on its input port 1128 (default) and forwards the messages
# over the same port to one or more receivers (e.g. server, 
# client, or another repeater). An FXC client establishes the
# connection by using the repeater's address in the Hosts.txt
# file and requesting the repeater to establish a connection
# with the desired server (also from Hosts.txt). Once the connection
# is established the server routes the reply back through the
# established path. If multiple clients are connected to the
# server the repeater sends the reply to all of the clients.
#
# Sample Hosts.txt entries:
#
# Denver           123.45.67.89         123.45.12.23
# Boulder          123.45.67.88:1122    123.45.12.22:1129
#                          ^                  ^
#           Repeater address and port   Server address and port
#
#
# The repeater accepts the following options:
#
# fxc.transceiver.hostaddress - normally is the host ip address
# fxc.transceiver.receiverport - if not defined, is 1128
# fxc.transceiver.sockettimeout - if not defined, is 15 sec
# fxc.transceiver.pruneinterval - if not defined, is 10 min
# fxc.transceiver.throughput - if not defined, is 20 KB/s
# fxc.transceiver.idletimeout - if not defined, is 20 min
# fxc.transceiver.sendthreads.min - if not defined, starts with 0
# fxc.transceiver.sendthreads.max - if not defined, is 8
# fxc.transceiver.receivethreads - if not defined, is 4
# java.security.policy - if not defined, is
# fxc.home - must specify where the FXC home directory can be found
# 

#  Determine location of FXC/fsl/linux directory
