Re: mailcap viewers in dired; gnus-dired.el, mailcap.el

    However, that hasn't been trivial in the past (what with the Emacs
    feature freeze that lasted two years and all).  When a new, general
    facility has been developed because Gnus needed it, it would be
    counter-productive to not distribute it with Gnus just because it's not
    Gnus-specific.

I don't mind if you distribute it with Gnus.  The point is to install it
into Emacs.

    But when merging, the general stuff should not end up in the Gnus
    directory, though.

If that means thinking of these added files as Emacs facilities rather
than as part of Gnus, that would do the job.
