+  # The Tokens encoder converts the tokens to a simple
+  # readable format. It doesn't use colors and is mainly
+  # intended for console output.
+  #
+  # The tokens are converted with Tokens.write_token.
+  #
+  # The format is:
+  #
+  #   <token-kind> \t <escaped token-text> \n
+  #
+  # Example:
+  #
+  #   require 'coderay'
+  #   puts CodeRay.scan("puts 3 + 4", :ruby).tokens
+  #
+  # prints:
+  #
+  #   ident   puts
+  #   space
+  #   integer 3
+  #   space
+  #   operator        +
+  #   space
+  #   integer 4
