I know this "--mirror" option. I used this solution to archive web page before.
Make this command work in org-attach is a little bit of complicated. I have
considered it on current org-attach code. With my Elisp ability, can't write it
out. Still not very good at Elisp :(

You can check out function `org-attach-attach` source code, the "cond" structure
is the most commands.

I remember org-attach dispatcher used to have a command to move directory
directly. But it seems removed. Now, all org-attach commands only supports file.
I also search Elisp functions, can't find a function to move directory around.
So PATCH welcome. I remember you send patch on Org Mode mailing list, I believe
you at least is same kind of newbie like me who can write a little Elisp. :)
