  /*The sitemap is helpful for robots and search engines,
  it informs them of all the important pages on the site for
  them to index. A sitemap is important for this site because
  not all the pages that are important are directly linked to.
  For example, some are linked with a javascript redirect.
  This code is created dynamically so there is no need to make
  any changes if you are just adding a page with the standard
  process.*/
