* Write our plugin * Include it * Move the RegEx * Don't rewriteLocalLinks with cheerio anymore * Process after HTML ast is generated * Use the same logic as before, just to see if it'll pass * Don't require languageCode/version * Only work on local links * Needs an href * Only update href if there's a new one to use * Check for node.properties * Some links are just mean
