 Each line includes a different range of nodes. The lines are processed in order and the results are merged. Any node range with a '-' in front of it removes that range from the current set. This can be used to remove non-functional nodes, or a particular class of nodes (ie. those nodes using intel wifi cards).

+== Sample Experiment Script ==

+The following is an example of a script that can be used to run a repeatable experiment:
+
+{{{
+# script to run the experiment
+
+# image the nodes
+./orbitImage nodeList baseline.ndz
+
+# wait until all the experiment nodes have booted
+./orbitPower nodeList on
+
+# Configure my wireless interface by running commands
+# on all experiment nodes and waiting until they complete.
+./orbitRunWait nodeList "iwconfig ath0 essid 'oontest'"
+./orbitRunWait nodeList "iwconfig ath0 channel 1"
+./orbitRunWait nodeList "iwconfig ath0 mode 'ad-hoc'"
+./orbitRunWait nodeList "iwconfig ath0 rate '11M'"
+./orbitRunWait nodeList "ifconfig ath0 192.168.%x.%y"
+
+# Copy the latest version of my application to each node
+./orbitPutFile nodeList myApp /root
+
+# Run my app on each experiment node, but don’t block
+./orbitRun nodeList "./myApp -i ath0"
+
+# delay while it does its thing
+sleep 60s
+
+# Some random command to ping every node from the console
+./orbitCmd nodeList "ping node%x-%y"
+
+# Kill off all the instances of my app running on the nodes
+./orbitKillAll nodeList "./myApp -i ath0"
+
+# copy and merge the logs from each node into one file on the console
+# this merged file can then be processed by your data analysis tools
+./orbitGetFileMerged nodelist ./route_logs.csv
+./orbitGetFileMerged nodelist ./error_rates.csv
+
+# shutdown the nodes in the experiment
+./orbitPower nodeList off
+}}}
+
+For more experiments I'd highly recommend removing the './orbitImage' and './orbitPower' commands to speed up the test/debug process considerably.
