+Long: retry
+Arg: <num>
+Added: 7.12.3
+Help: Retry request if transient problems occur
+---
+If a transient error is returned when curl tries to perform a transfer, it
+will retry this number of times before giving up. Setting the number to 0
+makes curl do no retries (which is the default). Transient error means either:
+a timeout, an FTP 4xx response code or an HTTP 5xx response code.
+
+When curl is about to retry a transfer, it will first wait one second and then
+for all forthcoming retries it will double the waiting time until it reaches
+10 minutes which then will be the delay between the rest of the retries.  By
+using --retry-delay you disable this exponential backoff algorithm. See also
+--retry-max-time to limit the total time allowed for retries.
+
+If this option is used several times, the last one will be used.
