Created December 5, 2012 21:31
Breadcrumbs builder for Foundation 3 & breadcrumbs_on_rails
# This gist was inspired by bootstrap breadcrumbs builder
# You can use it with the :builder option on render_breadcrumbs:
# <%= render_breadcrumbs :builder => ::FoundationBreadcrumbsBuilder, :separator => "&raquo;" %>
#
# Note: You may need to adjust the autoload_paths in your config/application.rb file for rails to load this class:
# config.autoload_paths += Dir["#{config.root}/lib/"]
#
class FoundationBreadcrumbsBuilder < BreadcrumbsOnRails::Breadcrumbs::Builder
