+SPDX-License-Identifier: curl
+Long: retry-delay
+Arg: <seconds>
+Help: Wait time between retries
+Added: 7.12.3
+Category: curl
+Example: --retry-delay 5 --retry $URL
+See-also: retry
+Multi: single
+---
+Make curl sleep this amount of time before each retry when a transfer has
+failed with a transient error (it changes the default backoff time algorithm
+between retries). This option is only interesting if --retry is also
+used. Setting this delay to zero will make curl use the default backoff time.
