Since there are web sites which contain hundreds of pages by one or a few authors working together, there is a desperate need for the development of a program which will automatically upgrade an entire website from its current below 5 HTML codes to HTML5. If not an entire site simultaneously, then at least one page at a time. It would take an enormous amount of time and effort to change 300+ webpages on a single site... leaving the author with no time to complete other pressing tasks.
