+// The git-remote-persistent-https binary speeds up SSL operations by running
+// a daemon job that keeps a connection open to a Git server. This ensures the
+// git-remote-persistent-https--proxy is running and delegating execution
+// to the git-remote-http binary with the http_proxy set to the daemon job.
+// A unix socket is used to authenticate the proxy and discover the
+// HTTP address. Note, both the client and proxy are included in the same
+// binary.
