Seeing Attachments in Gnus

[Dan Anderson]

        When somebody sends me an e-mail with an attachment under Gnus
I don't see that I've gotten one unless I am using verbose headers and
see that it's  a multipart e-mail, and even then  can't seem to figure
out how to extract them.  How do I:

        a.  Tell Gnus to alert me when an e-mail has an attachment
        b.  Tell Gnus where to save said attachment.

Thanks,

Dan
