# A generator that creates a sitemap.xml page for jekyll sites, suitable for submission to |
|||
# google etc. |
|||
# |
|||
# To use it, simply drop this script into the _plugins directory of your Jekyll site. |
|||
# |
|||
# When you compile your jekyll site, this plugin will loop through the list of pages in your |
|||
# site, and generate an entry in sitemap.xml for each one. |
