+This is an implementation of Hypertext Transfer Protocol version 2
+in C.
+
+The framing layer of HTTP/2 is implemented as form of reusable C
+library.  On top of that, we have implemented HTTP/2 client, server
+and proxy.  Also we have developed load test/benchmarking tool for
+HTTP/2 and SPDY.
+
+HPACK encoding and decoding are available as public API.
+
+We didn't cover everything, but we have Python binding of this libary.
