bootstrap_breadcrumbs_builder.rb
#
# The BootstrapBreadcrumbsBuilder is a Bootstrap compatible breadcrumb builder.
# It provides basic functionalities to render a breadcrumb navigation according
# to Bootstrap's conventions.
#
# You can use it with the :builder option on render_breadcrumbs:
# <%= render_breadcrumbs builder: ::BootstrapBreadcrumbsBuilder %>
#
# 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 BootstrapBreadcrumbsBuilder < BreadcrumbsOnRails::Breadcrumbs::Builder
