+	  Pexpect is a pure Python module for spawning child
+	  applications; controlling them; and responding to expected
+	  patterns in their output. Pexpect works like Don Libes’
+	  Expect. Pexpect allows your script to spawn a child
+	  application and control it as if a human were typing
+	  commands.
