My Ikiwiki and blog has structure

/website
blog.mdwn
...

/website/blog
/website/blog/blog1.mdwn
/website/blog/blog2.mdwn
...

After running

ikiwiki-calendar ./foo.setup "/blog/*"

I got a

/website/archives/

and archive pages in it.

I'd like to have it in

/website/blog/archives/

as those are archive pages for blog pages only. How to do it?
