 # Package org.phoebus.pv.ca
 # -------------------------
 
+# By default, we use the following preferences settings,
+# but when the System property "jca.use_env" is "true",
+# JCA falls back to the EPICS_CA_... environment variables.
+#
+# Sites that prefer to use the EPICS_CA_... environment variables
+# thus need to add
+#
+#      -Djca.use_env=true
+#
+# to their launcher script.
