+# This script builds the client and server binaries and runs them in a tmux
+# session side-by-side. The client connects to the server and the server
+# responds with a simple HTTP response. The client and server are run with
+# verbose logging and the qlog output is stored in a temporary directory. The
+# script also runs tcpdump to capture the packets exchanged between the client
+# and server. The script uses tmux to create a split terminal window to display
+# the qlog output and the packet capture.
