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?
