# Title: Simple Code Blocks for Jekyll
# Author: Brandon Mathis http://brandonmathis.com
# Description: Write codeblocks with semantic HTML5 and elements and optional syntax highlighting — all with a simple, intuitive interface.
#
# Syntax:
# {% codeblock [title] [url] [link text] %}
# code snippet
# {% endcodeblock %}
#
# For syntax highlighting, put a file extension somewhere in the title. examples:
# {% codeblock file.sh %}
# code snippet
# {% endcodeblock %}
#
# {% codeblock Time to be Awesome! (awesome.rb) %}
# code snippet
# {% endcodeblock %}
#
# Example:
#
# {% codeblock Got pain? painreleif.sh http://site.com/painreleief.sh Download it! %}
# $ rm -rf ~/PAIN
# {% endcodeblock %}
#
# Output:
#
#
# Got pain? painrelief.sh Download it!
#
# -- nicely escaped highlighted code --
#
<sarcasm> Ooooh, sarcasm... How original!</sarcasm>
