+Help: Trigger 'speed-limit' abort after this time
+---
+If a download is slower than speed-limit bytes per second during a speed-time
+period, the download gets aborted. If speed-time is used, the default
+speed-limit will be 1 unless set with --speed-limit.
+
+This option controls transfers and thus will not affect slow connects etc. If
+this is a concern for you, try the --connect-timeout option.
+
+If this option is used several times, the last one will be used.
