	# Mac fix 1 - Install the Nokogiri gem on Mac OS 10.9 Mavericks
	#
	# Usage: to configure and install using Bundler, pass in 'bundle' as an argument to the script.
	#
	# Nokogiri works at a very low level, so it has many issues on various platforms.
	# As a result, the command `install gem nokogiri` often will fail. This fix is for
	# errors involving 'libiconv', such as the following one I encountered:
	#

	module ImagesHelper
	# Acts as a thin wrapper for image_tag and generates an srcset attribute for regular image tags
	# for usage with responsive images polyfills like picturefill.js, supports asset pipeline path helpers.
