These instructions should help you invoke the proper version of emacsc and lead you to the Emacs tutorial. These commands need only be done once, as they establish a link to the appropriate course files and allow you to use the modified version of Emacs which is invoked for each future session with the name emacsc. If you are not enrolled in one of the courses supported in the course database, you can still get access to emacsc and the tutorial. Two additional arguments are used with the init-course program. If you specify -ls, a list of the courses you have added will be displayed.
