It’s also uploaded to http://melpa.org. The best way to install is Emacs package manager.
M-x dianyou-group-make-nnir-group to search mail in any Gnus buffer. It’s similar to
gnus-group-make-nnir-group but supports shortcuts when using IMAP search command.
For example, input
s 2w f John, then select “imap” when asked how to search. Mails from John sent since 2 weeks ago are returned.

The accessed email address is automatically stored in variable
dianyou-email-address-history, which could be persisted by session.

M-x dianyou-paste-image-from-clipboard to paste image from clipboard (CLI program xclip should be installed at first).
