+# example, to hit the server with 150 simultaneous SPDY clients, each fetching
+# the URLs https://example.com/ and https://example.com/image.jpg, you would
+# run:
+#
+#  $ ./loadtest.py spdy 150 https://example.com/ https://example.com/image.jpg
+#
+# To run the same test with plain HTTPS clients instead of SPDY clients (for
+# comparison), you would run:
+#
+#  $ ./loadtest.py https 150 https://example.com/ https://example.com/image.jpg
+#
+# Press Ctrl-C to stop the test.
+#
+# You must have spdycat (https://github.com/tatsuhiro-t/spdylay) installed and
+# on your $PATH in order to run SPDY tests, and you must have curl installed in
+# order to run HTTPS or HTTP tests.
