Re: Recognize mbox files?

[Richard M Stallman]

    I still do not understand how this will work for find-file on a RMAIL
    file.  Before you could just do C-x C-f on a RMAIL file, and it would
    open in rmail-mode.  Could someone explain how this would work by
    using X-RMAIL-ATTRIBUTES?

Emacs would check for X-RMAIL-ATTRIBUTES: in the first message,
find it, and visit the file using Rmail.
