    # The header_matchers plugin adds hash matchers for matching on less-common
    # HTTP headers.
    #
    #   plugin :header_matchers
    #
    # It adds a +:header+ matcher for matching on arbitrary headers, which matches
    # if the header is present:
    #
    #   route do |r|
    #     r.on :header=>'X-App-Token' do
    #     end
    #   end
    #
    # It adds a +:host+ matcher for matching by the host of the request:
    #
    #   route do |r|
    #     r.on :host=>'foo.example.com' do
    #     end
    #   end
    #
    # It adds an +:accept+ matcher for matching based on the Accept header:
    #
    #   route do |r|
    #     r.on :accept=>'text/csv' do
    #     end
    #   end
    #
    # Note that the accept matcher is very simple and cannot handle wildcards,
    # priorities, or anything but a simple comma separated list of mime types.
