+# This script refreshes WBEM/CIM MOF & REG files from the current PCP PMNS,
+# if necessary, and reloads the new MOF/REGs into the CIMMON.
+#
+# The PCP PMNS changes infrequently (when the sysadmin manuall installs or
+# removes pcp PMDA (agent) modules in /var/lib/pcp/pmdas/*).
+#
+# This script encodes the PCP->CIM metric name-mapping convention of replacing
+# dots with double-underscores, which lmi/pcp/metric.py will dutifully undo.
