Here's a small patch which changes the major mode from outline-mode to
org-mode in some files:

CONTRIBUTE
etc/CALC-NEWS
etc/DEBUG
etc/MACHINES
etc/PROBLEMS
etc/TODO

I believe org-mode is vastly more well-known and arguably also more
intuitive to users.  IME and IMO, just the simple fact that you can
cycle headlines with TAB in org-mode makes things a whole lot easier.
