The new static build process is now complete, including all the DC header stuff, the teiHeader display widget, and the search page (which of course won't do anything until it's in the context of a webapp). With HT's approval, I have now switched all the old URLs over to the new on the existing site, and added 301 redirects through the sitemap.xmap. See the relevant stanzas there to see how it's done; I doubt we'll ever need to do this sort of thing again with such an old Cocoon, but it took me a while to figure out. I still need to add validation to the build process.
