+# == Using plugin assets for form tag helpers
+#
+# It's as easy to use plugin images for image_submit_tag using Engines as it is for image_tag:
+#
+#   <%= image_submit_tag "my_face", :plugin => "my_plugin" %>
+#
+# ---
+#
+# This module enhances one of the methods from ActionView::Helpers::FormTagHelper:
+#
+#  * image_submit_tag
+#
+# This method now accepts the key/value pair <tt>:plugin => "plugin_name"</tt>,
+# which can be used to specify the originating plugin for any assets.
+#
