# == 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.
#
