+# This pod specification creates an instance of a synthetic logger. The logger
+# is simply a program that writes out the hostname of the pod, a count which increments
+# by one on each iteration (to help notice missing log enteries) and the date using
+# a long format (RFC-3339) to nano-second precision. This program logs at a frequency
+# of 0.25 lines per second. The shellscript program is given directly to bash as -c argument
+# and could have been written out as:
+#   i="0"
+#   while true
+#   do
+#     echo -n "`hostname`: $i: "
+#     date --rfc-3339 ns
+#     sleep 4
+#     i=$[$i+1]
