-# Title: Include Code Tag for Jekyll
-# Author: Brandon Mathis http://brandonmathis.com
-# Description: Import files on your filesystem into any blog post as embedded code snippets with syntax highlighting and a download link.
-# Configuration: You can set default import path in _config.yml (defaults to code_dir: downloads/code)
-#
-# Syntax {% include_code path/to/file %}
-#
-# Example 1:
-# {% include_code javascripts/test.js %}
-#
-# This will import test.js from source/downloads/code/javascripts/test.js
-# and output the contents in a syntax highlighted code block inside a figure,
-# with a figcaption listing the file name and download link
-#
-# Example 2:
-# You can also include an optional title for the <figcaption>
-#
-# {% include_code Example 2 javascripts/test.js %}
-#
-# will output a figcaption with the title: Example 2 (test.js)
-#
