+jclouds OkHttp driver
+=====================
+
+A driver to use the OkHttp (http://square.github.io/okhttp/) client as an HTTP library in jclouds.
+
+This driver adds support for use of modern HTTP verbs such as PATCH in providers and APIs, and also supports SPDY.
+
+To use the driver, you just need to include the `OkHttpCommandExecutorServiceModule` when creating
+the context:
+
+    ContextBuilder.newBuilder("provider")
+        .endpoint("endpoint")
+        .credentials("identity", "credential")
+        .modules(ImmutableSet.of(new OkHttpCommandExecutorServiceModule()))
+        .build();
