# A generator that creates tag pages for jekyll sites.
#
# Included filters :
# - tag_links: Outputs the list of tags as comma-separated <a> links.
# - date_to_html_string: Outputs the post.date as formatted html, with hooks for CSS styling.
#
# Available _config.yml settings :
# - tag_dir: The subfolder to build tag pages in (default is 'tags').
# - tag_title_prefix: The string used before the tag name in the page title (default is
# 'Tag: ').
