-  # An experimental implementation of HMAC keyed-hashing algorithm
-  #
-  # == Overview
-  #
-  # CAUTION: Use of this library is discouraged, because this
-  # implementation was meant to be experimental but somehow got into the
-  # 1.9 series without being noticed.  Please use OpenSSL::HMAC in the
-  # "openssl" library instead.
-  #
-  # == Examples
-  #
-  #   require 'digest/hmac'
-  #
-  #   # one-liner example
-  #   puts Digest::HMAC.hexdigest("data", "hash key", Digest::SHA1)
-  #
-  #   # rather longer one
-  #   hmac = Digest::HMAC.new("foo", Digest::RMD160)
-  #
-  #   buf = ""
-  #   while stream.read(16384, buf)
-  #     hmac.update(buf)
-  #   end
-  #
-  #   puts hmac.hexdigest
-  #
-  class HMAC < Digest::Class
