How to base64 decode and gunzip, *easily*, in RMAIL?

In RMAIL mode, using a plain vanilla instance of Emacs 21, 
started with no .emacs or site file, and no blinking cursor:

        emacs -q --no-site-file --eval '(blink-cursor-mode 0)'

what do people do to decode a gzip'd email message that is base64 encoded?


Using today's CVS snapshot, Fri, 2001 Dec 28 12:57 UTC,
in RMAIL, I did the following, which works, but is inefficient;

    1.  Change the read-only status of the RMAIL buffer using 
        `C-x C-q', which runs the command `vc-toggle-read-only':

            C-x C-q

    2.  Execute `base64-decode-region' on *only* the encoded region,
        not any other part:

            M-x base64-decode-region

    3.  On the region, run `M-|', which runs the command
        `shell-command-on-region':

            M-| gzip -d RET

    4.  Copy the contents of the resulting *Shell Command Output*
        buffer to the appropriate file.
