+Export all records created or edited after a given date
+=======================================================
+
+To better support periodic batch exports of new or changed MARC records, the
+`marc_export` script now accepts two additional command line options that
+combine with the `--all` flag:
+
+* `--since / -s` : Exports records created since the date in 'YYYY-MM-DD' format
+* `--edited` : Exports records edited since the date in 'YYYY-MM-DD' format
