+# Jekyll category page generator.
+# http://recursive-design.com/projects/jekyll-plugins/
+#
+# Version: 0.1.4 (201101061053)
+#
+# Copyright (c) 2010 Dave Perrett, http://recursive-design.com/
+# Licensed under the MIT license (http://www.opensource.org/licenses/mit-license.php)
+#
+# A generator that creates category pages for jekyll sites.
+#
+# To use it, simply drop this script into the _plugins directory of your Jekyll site. You should
+# also create a file called 'category_index.html' in the _layouts directory of your jekyll site
+# with the following contents (note: you should remove the leading '# ' characters):
+#
+# ================================== COPY BELOW THIS LINE ==================================
+# ---
+# layout: default
+# ---
+#
+# <h1 class="category">{{ page.title }}</h1>
+# <ul class="posts">
+# {% for post in site.categories[page.category] %}
+#     <div>{{ post.date | date_to_html_string }}</div>
+#     <h2><a href="{{ post.url }}">{{ post.title }}</a></h2>
+#     <div class="categories">Filed under {{ post.categories | category_links }}</div>
+# {% endfor %}
+# </ul>
+# ================================== COPY ABOVE THIS LINE ==================================
+#
+# You can alter the _layout_ setting if you wish to use an alternate layout, and obviously you
+# can change the HTML above as you see fit.
+#
+# When you compile your jekyll site, this plugin will loop through the list of categories in your
+# site, and use the layout above to generate a page for each one with a list of links to the
+# individual posts.
+#
+# Included filters :
+# - category_links:      Outputs the list of categories 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 :
+# - category_dir:          The subfolder to build category pages in (default is 'categories').
+# - category_title_prefix: The string used before the category name in the page title (default is
+#                          'Category: ').

+# Sitemap.xml Generator is a Jekyll plugin that generates a sitemap.xml file by
+# traversing all of the available posts and pages.
+# 
+# How To Use:
+#   1) Copy source file into your _plugins folder within your Jekyll project.
+#   2) Change modify the url variable in _config.yml to reflect your domain name.
+#   3) Run Jekyll: jekyll --server to re-generate your site.
+#
+# Variables:
+#   * Change SITEMAP_FILE_NAME if you want your sitemap to be called something
+#     other than sitemap.xml.
+#   * Change the PAGES_INCLUDE_POSTS list to include any pages that are looping
+#     through your posts (e.g. "index.html", "archive.html", etc.). This will
+#     ensure that right after you make a new post, the last modified date will
+#     be updated to reflect the new post.
+#   * A sitemap.xml should be included in your _site folder.
+#   * If there are any files you don't want included in the sitemap, add them
+#     to the EXCLUDED_FILES list. The name should match the name of the source
+#     file.
+#   * If you want to include the optional changefreq and priority attributes,
+#     simply include custom variables in the YAML Front Matter of that file.
+#     The names of these custom variables are defined below in the
+#     CHANGE_FREQUENCY_CUSTOM_VARIABLE_NAME and PRIORITY_CUSTOM_VARIABLE_NAME
+#     constants.
+#
+# Notes:
+#   * The last modified date is determined by the latest from the following:
+#     system modified date of the page or post, system modified date of
+#     included layout, system modified date of included layout within that
+#     layout, ...
