# The run_append_slash plugin makes +r.run+ use +/+ as the +PATH_INFO+
# when calling the rack application if +PATH_INFO+ would be empty.
# Example:
#
# route do |r|
# r.on "a" do
# r.run App
# end
# end
#
# # without run_append_slash:
# # GET /a => App gets "" as PATH_INFO
# # GET /a/ => App gets "/" as PATH_INFO
#
# # with run_append_slash:
# # GET /a => App gets "/" as PATH_INFO
# # GET /a/ => App gets "/" as PATH_INFO

# :use_redirects :: Whether to issue 302 redirects when appending the
