 The session pipes the command's stdout and stderr to two *gbytes.Buffers available as properties on the session: session.Out and session.Err.
 These buffers can be used with the gbytes.Say matcher to match against unread output:
 
-	Ω(session.Out).Should(gbytes.Say("foo-out"))
-	Ω(session.Err).Should(gbytes.Say("foo-err"))
+	Expect(session.Out).Should(gbytes.Say("foo-out"))

 In addition, Session satisfies the gbytes.BufferProvider interface and provides the stdout *gbytes.Buffer.  This allows you to replace the first line, above, with:
 
-	Ω(session).Should(gbytes.Say("foo-out"))
+	Expect(session).Should(gbytes.Say("foo-out"))
 
 When outWriter and/or errWriter are non-nil, the session will pipe stdout and/or stderr output both into the session *gybtes.Buffers and to the passed-in outWriter/errWriter.
 This is useful for capturing the process's output or logging it to screen.  In particular, when using Ginkgo it can be convenient to direct output to the GinkgoWriter:

 The session wrapper is responsible for waiting on the *exec.Cmd command.  You *should not* call command.Wait() yourself.
 Instead, to assert that the command has exited you can use the gexec.Exit matcher:

 When the session exits it closes the stdout and stderr gbytes buffers.  This will short circuit any
