+The Exit matcher operates on a session:
+
+	Expect(session).Should(Exit(<optional status code>))
+
+Exit passes if the session has already exited.
+
+If no status code is provided, then Exit will succeed if the session has exited regardless of exit code.
+Otherwise, Exit will only succeed if the process has exited with the provided status code.
+
+Note that the process must have already exited.  To wait for a process to exit, use Eventually:
+
+	Eventually(session, 3).Should(Exit(0))
