+# Looks at each link on a page (or in all the pages in a category) which uses a registered
+# interwiki prefix and loads the linked page, verifying that it exists and that any section
+# link, if present, is valid as well. The output will use the word "ERROR" when it cannot
+# validate the interwiki link.
