sitemap(tree, host)

Generates a basic sitemap for the given tree so that it can be more easily crawled by search engines. The sitemap function prepends the indicated host URL to all paths in the tree to generate a list of the search engine should visit.

Example: if tinySite.ori contains:

// tinySite.ori
{
  index.html: `
    <h1>Home</h1>
    <a href="about.html">About</a>
  `

  about.html: "<h1>About</h1>"
}

then calling sitemap generates:

$ ori sitemap tinySite.ori, "'https://mysite.org'"
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://mysite.org/</loc>
  </url>
  <url>
    <loc>https://mysite.org/about.html</loc>
  </url>
</urlset>
