+sigsum-debug spam sends many requests to a sigsum log
+
+Usage:
+
+  sigsum-debug spam leaf -u URL -k KEY -h DOMAIN_HINT [-d DURATION]
+      [-i INTERVAL] [-w WAIT] [-s SUBMITTERS] [-c CHECKERS]
+
+    Sends add-leaf requests to a sigsum log from one or more parallel
+    submitters.  Use the -c option to also check for 200 OK responses.
+    Unless the -w flag is specified, you then need ~5x more checkers.
+
+    Options:
+    -u, --log-url      URL of a log to spam with add-leaf requests
+    -k, --private-key  Private key to sign checksums with in hex
+    -h, --domain-hint  Domain hint for the specified private key
+    -d, --duration     Duration to run sigsum-spam (Default: 5m)
+    -i, --interval     Duration between emitting stats (Default: 1s)
+    -w, --wait         Time to wait between submits (Default: 0s)
+    -s, --submitters   Number of submitters to use (Default: 1)
+    -c, --checkers     Number of checkers to use (Default: 0)
