+  # === :tab_width
+  # Convert \t characters to +n+ spaces (a number.)
+  # Default: 8

+  # === :css
+  # How to include the styles; can be :class or :style.
+  #

+  # === :title
+  # 
+  # The title of the HTML page (works only when :wrap is set to :page.)

+  # Default: 'CodeRay output'
+  #
+  # === :line_numbers
+  # Include line numbers in :table, :inline, :list or nil (no line numbers)

+  # Default: nil
+  #
+  # === :line_number_start
+  # Where to start with line number counting.
+  #
+  # Default: 1

+  # 
+  # Highlights certain line numbers.
+  # Can be any Enumerable, typically just an Array or Range, of numbers.
