Modifying emacs to display colors for C++ files.

1) Use putty to connect to sybil (refer to tutorials and other pages)

2) DO NOT cd into your csi201 directory. This is the only time that
   you should not do this. The reason that we are not doing this is
   because we are editing an emacs configuration file.

3) Type:
        emacs .emacs

Be sure not to forget the period in front of the second emacs word.

4) At the top of this file, Type:
        (global-font-lock-mode t)

5) Type:
        ctrl-x ctrl-s

6) Type:
        ctrl-x ctrl-c

7) Open a C++ file to confirm that you do indeed have colors. (See
   previous pages for instructions on how to open a C++ file.) If no
   colors appear, return to step 2!
