;;; This module provides tools to test the guided "graphical" installer in a

|
|
;;; state Expect-style dialogues, which happen over the Unix-domain socket the
|
|
;;; installer listens to. Higher-level procedures such as
|
|
;;; 'choose-locale+keyboard' are provided to perform specific parts of the
|
|
;;; dialogue.
