Re-running an import #

An import can always run again; that is how a site stays in step with its source.

• Identity. Every page is the object with the remote id staticimport-<type>-<md5 of its source path>, wherever it has been moved to.
• Changed source. The page is updated: a new version, published.
• Unchanged source. Nothing is written.
• Edited in the CMS. The import keeps the hash of what it wrote. When the object no longer has that content, the page is flagged and left alone. --overwrite-flagged writes it anyway, and the edit is lost.
• Left the source. The node is hidden and reported. --apply-removals moves it to the trash instead.
• Copies. A page with the same content as one already imported (DuplicatePatterns[]) and a redirect stub become redirects to that page; error pages are skipped.
• Old paths. Every page's source path, with and without .html, answers with a redirect to its node.
