+# The BootstrapBreadcrumbsBuilder is a Bootstrap compatible breadcrumb builder.
+# It provides basic functionalities to render a breadcrumb navigation according to Bootstrap's conventions.
+#
+# BootstrapBreadcrumbsBuilder accepts a limited set of options:
+# * separator: what should be displayed as a separator between elements
+#
+# You can use it with the :builder option on render_breadcrumbs:
+#     <%= render_breadcrumbs :builder => ::BootstrapBreadcrumbsBuilder, :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/"]
+#
