// A binary wrapper for QuicClient.
// Connects to a host using QUIC, sends a request to the provided URL, and
// displays the response.
//
// Some usage examples:
//
// Standard request/response:
//   quic_client www.google.com
//   quic_client www.google.com --quiet
//   quic_client www.google.com --port=443
//
// Use a specific version:
//   quic_client www.google.com --quic_version=23
//
// Send a POST instead of a GET:
//   quic_client www.google.com --body="this is a POST body"
//
// Append additional headers to the request:
//   quic_client www.google.com --headers="header-a: 1234; header-b: 5678"
//
// Connect to a host different to the URL being requested:
//   quic_client mail.google.com --host=www.google.com
//
// Connect to a specific IP:
//   IP=`dig www.google.com +short | head -1`
//   quic_client www.google.com --host=${IP}
//
// Send repeated requests and change ephemeral port between requests
//   quic_client www.google.com --num_requests=10
//
// Try to connect to a host which does not speak QUIC:
//   quic_client www.example.com
//
// This tool is available as a built binary at:
