Before you can run MzScheme from within Emacs, you need to create a
.emacs file in your home directory. The .emacs file
should contain a single line:
(load-file "~cslab/.emacs")
Once Emacs is up and running, type Esc x. Emacs will print
M-x on the command input line and wait for your command. To
run MzScheme, type run-scheme and hit enter.
