Hi all,

In the attached patch I add a new command for org-attach: save *all*
attachments from the current Gnus article to the current org-attach-dir.

(Sorry for repeating the word "attach" so much :-))

NB:

1. If no Gnus article is open, it returns an error message.

2. I've only tested it on Emacs 28. I don't know if it can cause any
problems on earlier Emacs/Gnus versions.

3. Although there are several alternatives to Gnus, I have chosen Gnus
specifically because it is part of GNU Emacs.

4. I think an option could be added to save only certain types of files
(pdf, png, jpg, docx, etc.).

Best regards,

Juan Manuel
