Sigh. Now with the correct, up-to-date patch and gnurl support.

Kind regards,

+A reusable C library provides the HTTP/2 framing layer, with several tools built

+
+@enumerate
+@item @command{nghttp}, a command-line HTTP/2 client.  It exposes many advanced
+and low-level aspects of the protocol and is useful for debugging.
+@item @command{nghttpd}, a fast, multi-threaded HTTP/2 static web server that
+serves files from a local directory.
+@item @command{nghttpx}, a fast, multi-threaded HTTP/2 reverse proxy that can be
+deployed in front of existing web servers that don't support HTTP/2.
+Both @command{nghttpd} and @command{nghttpx} can fall back to HTTP/1.1 for
+backwards compatibilty with clients that don't speak HTTP/2.
+@item @command{h2load} for benchmarking (only!) your own HTTP/2 servers.
+@item HTTP/2 uses a header compression method called @dfn{HPACK}.
+nghttp2 provides a HPACK encoder and decoder as part of its public API.
+@item @command{deflatehd} converts JSON data or HTTP/1-style header fields to
+compressed JSON header blocks.
+@item @command{inflatehd} converts such compressed headers back to JSON pairs.
