+// Package xhandler provides a bridge between http.Handler and net/context.
+//
+// xhandler enforces net/context in your handlers without sacrificing
+// compatibility with existing http.Handlers nor imposing a specific router.
+//
+// Thanks to net/context deadline management, xhandler is able to enforce
+// a per request deadline and will cancel the context in when the client close
+// the connection unexpectedly.
+//
+// You may create net/context aware middlewares pretty much the same way as
+// you would do with http.Handler.
