+# historyTruncateDb.sh  -- This tool is usually run from a cron.  
+#    It uses the application.property "history.truncate.window.days" to look for 
+#    and delete nodes and edges that have an end-ts earlier than the truncate window.
+#    Or, that can be over-ridden using the command line param, "-truncateWindowDays".
+#    That is - they were deleted from the 'real' database before the window.
+#    So, if the window is set to 90 days, we will delete all nodes and edges 
+#    from the history db that were deleted from the real db more than 90 days ago.
+#
+#    It also uses the property, "history.truncate.mode".  Can be over-ridden using
+#    the command line property "-truncateMode"
+#       "LOG_ONLY" - look for candidate nodes/edges, but just log them (no deleting)
+#       "DELETE_AND_LOG" - like it says...  does the deletes and logs what 
+#              it deleted (node and edge properties)
+#       "SILENT_DELETE"  - not entirely silent, but will pare the logs way back to
+#              just recording vertex and edge ids that are deleted. 
+#
+#    Ie.    historyTruncateDb.sh -truncateWindowDays 60 -truncateMode LOG_ONLY
