# Executes #capture on the global ActionView and sets <tt>name</tt> as the

# Example:
#
# <p>
# <% global_capture :greeting do
# <h1>Hi, Nick!</h1>
# <% end %>
#
# The captured markup can be accessed in your global action view or in your layout.

# <%= @greeting %>

# Example:
#
# <p>
# <% global_content_for :greetings do
# <h1>Hi, Michal!</h1>

# As in global_capture, the markup can be accessed in your global action view or in your layout.
