+# ===============================
+# This a modified version RunLearningObserver.sh that automatically starts two processes,
+# each with a different creds.yaml ('creds-a.yaml' and 'creds-b.yaml')--this should be
+# used for static routing, where one creds.yaml has only dashboard routes enabled,
+# and the other has only extension routes enabled. Note that these creds.yaml should 
+# specify different ports.
+# 
+# This bash script provides a simple wrapper to run the 
+# learning observer service and pipe the data to a logfile
+# over time this should be integrated into the systemd 
+# service process.  This uses static variables to specify
+# the location of the virtualenv and the command and 
+# specifies the location for the running logfile.
