+# 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
