+Feature: DRb Server Integration: Regression test for Issue #117
+  To prevent waiting for Rails and other large Ruby applications to load their environments
+  for each feature run Cucumber ships with a DRb client that can speak to a server which
+  loads up the environment only once.
+
+  This regression test highlights bug related to DRb server arguments processing, for more
+  details see https://github.com/cucumber/cucumber/issues/117
+
+  Background: App with Spork support
+    Spork is a gem that has a DRb server and the scenarios below illustrate how to use it.
+    However, any DRb server that adheres to the protocol that the client expects would work.
