# The run_handler plugin allows r.run to take a block, which is yielded
# the rack response array, before it returns it as a response.
#
# Additionally, r.run also takes a options hash, and you can provide a
# <tt>:not_found=>:pass</tt> option to keep routing normally if the rack
# app returns a 404 response.
