+Spdylay - SPDY C Library
+========================
+
+This is an experimental implementation of Google's SPDY protocol
+version 2 in C.
+
+The current status of development is in very early stage. Not all
+control frames have not been implemented yet.  But ``spdycl`` in
+*examples* directory can connect to SPDY-capable server via SSL and
+select spdy/2 with NPN and get a resource given in command-line.
