+# Mnemonic: run_multi_test.ksh
+# Abstract: This is a simple script to set up and run the basic send/receive
+# processes for some library validation on top of nano/nng. This
+# particular tests starts several receivers and creates a route table
+# which causes messages to be sent round robin to all of the receivers.
+# The number of messages command line parameter (-n) will be the number
+# of messages that each receiver should expect; the sender will be asked
+# to send r times that many messages so that as they are round robbined
+# each receiver should get the same number of messages.
+#
+# Example command line:
+# ksh ./run_rr_test.ksh # default 10 messages at 1 msg/sec
+# ksh ./run_rr_test.ksh -N # default but with nanomsg lib
+# ksh ./run_rr_test.ksh -d 100 -n 10000 # send 10k messages with 100ms delay between
+#
