   When setting rmail-enable-mime in my .emacs to t, I get a backtrace

I believe that `rmail-enable-mime' does not work unless you install
some package (not included in Emacs by default) whose name I forgot,
even though the docstring suggests that all you have to do is set it
to t to make it work.  This has confused many people in the nine years
since this variable was first introduced.

If you have no extra Emacs packages installed, set rmail-enable-mime
to t and do `M-x rmail' you get:

Feature `rmail-mime' not provided

There is a lot of code in CVS Emacs related to `rmail-enable-mime', but
I believe that this code is only meant to support the external package.
Maybe somebody more familiar with the feature than I am can shed more
light on this.
