61 | ;;; | |
62 | ;;; This module provides the infrastructure to run operating system tests. | |
63 | ;;; The most important part of that is tools to instrument the OS under test, | |
64 | ;;; essentially allowing to run in a virtual machine controlled by the host | |
65 | ;;; system--hence the name "marionette". | |
