# The content_for plugin is designed to be used with the
# render plugin, allowing you to store content inside one
# template, and retrieve that content inside a separate
# template. Most commonly, this is so view templates
# can set content for the layout template to display outside
# of the normal content pane.
#
# The content_for template probably only works with erb
# templates, and requires that you don't override the
# +:outvar+ render option. In the template in which you
# want to store content, call content_for with a block:
#
# <% content_for :foo do %>
# Some content here.
# <% end %>
#
# In the template in which you want to retrieve content,
# call content_for without the block:
#
# <%= content_for :foo %>

# If called with a block, store content enclosed by block
# under the given key. If called without a block, retrieve
# stored content with the given key, or return nil if there
# is no content stored with that key.
