+
+    # = LaTeX Encoder
+    #
+    # Encode CodeRay tokens to LaTeX so you can use CodeRay’s
+    # superior highlighting in LaTeX’s superior typesetting.
+    # The LaTeX code generated depends on one single LaTeX package,
+    # `xcolor`, which has to be loaded as usual.
+    #
+    # The generated LaTeX code is a large blob of specific commands
+    # that typeset a monospaced section of text. It does _not_ use
+    # LaTeX’s `verbatim` environment, hence placing the result
+    # at certain places where this is problematic should be possible.
+    # The code makes use of a number of custom commands that
+    # are not defined by default. You can retrieve these by
+    # calling ::preamble_snippet, which also defines all the
+    # colors and styling used in the highlighting code.
+    #
+    # Each highlight block automatically switches to vertical mode
+    # and executes <tt>\par</tt> at its end, so whatever follows
+    # starts a new paragraph. Highlighting blocks also execute
+    # <tt>\noindent</tt> at the beginning, so they will never be
+    # subject to LaTeX’s paragraph indentation.
+    #
+    # Highlighting blocks are not floating. They will be inserted
+    # right where you include them. You can build your own floating
+    # environment around them if you want.
+    #
+    # Before you can use a CodeRay-highlighted block in your LaTeX
+    # document, you have to include some code in your preamble. You
+    # can retrieve this code by calling ::preamble_snippet. It defines
+    # some helper commands and, most importantly, the colors used so
+    # that you can easily adapt it to your likening.
+    #
+    # == Unicode notice
+    #
+    # Today’s sourcecode files often contain Unicode characters.
+    # When confronted with such a file, typesetting the result of
+    # the CodeRay highlighting process with pdflatex will fail
+    # like this:
+    #
+    #   ! Package inputenc Error: Unicode char \u8:─ not set up for use with LaTeX.
+    #
+    # Use a Unicode-aware TeX implementation such as LuaTex (LuaLaTeX)
+    # instead, and all will work fine. You should be doing that
+    # anyway.
+    #
+    # == Usage
+    #
+    # Ruby code:
+    #
+    #   require "coderay"
+    #   puts CodeRay.scan('Some /code/', :ruby).latex #=> LaTeX snippet
+    #   puts CodeRay.scan('Some code', :ruby).latex(
+    #     :line_numbers => true,
+    #     :mix_delimiters => true)
+    #  )
+    #
+    # LaTeX code (for LuaLaTeX):
+    #
+    #   \documentclass[11pt,a4paper]{scrartcl} % Whatever you like
+    #   \usepackage[ngerman]{babel} % Whatever you like
+    #   \usepackage{fontspec} % Not required, but recommended
+    #   \usepackage{xcolor} % Required
+    #
+    #   \include{coderay-preamble} % Result of the ::preamble_snippet method!
+    #   \begin{document}
+    #   \input{hilit} % This should contain a coderay-highlited LaTeX snippet.
+    #   \end{document}
+    #
+    # == Options
+    #
+    # === :tab_width
+    # Number of spaces to insert for a tabulation character.
+    # Behaves slightly different if <tt>:show_whitespace</tt>
+    # is given also, see there for explanation.
+    #
+    # === :line_numbers
+    # Print the line number in front of each line. You can customize
+    # the look by redefining the `\coderaylinumstyle` command.
+    #
+    # === :line_numbers_start
+    # Number of the first line.
+    #
+    # Default: 1
+    #
+    # Default: false
+    #
+    # === :bold_every
+    # Format every nth line bold, where n is the value of this
+    # option. Actually, you can influence the format the
+    # way you like, just redefine `\coderayboldlinumstyle`,
+    # which is applied after `\coderaylinumstyle`.
+    #
+    # Default: 10
+    #
+    # === mix_delimiters
+    # Use `xcolor`’s color mixing facilities to make inline
+    # delimiters (e.g. for strings and inline code) look
+    # more appealing by mixing their color together from
+    # the nesting element colors.
+    #
+    # === show_whitespace
+    # Use a replacement character (U+2432 OPEN BOX, ␣) to emphasize the
+    # presence of spaces.
+    #
+    # Tabs are also replaced with emphasizing characters, in this
+    # case U+2500 and U+25BB (─▻) where the length of the arrow shaft
+    # is determined by the <tt>:tab_width</tt> option.
+    #
+    # Requires a Unicode-aware LaTeX engine such as LuaLaTeX (pdflatex
+    # won’t work probably), and a font supporting the used glyphs. At
+    # time of writing (April 2015), Computer Modern Typewriter,
+    # LaTeX’s default monospace font, supports the U+2432 character,
+    # but not the U+2500 and U+25BB characters.
+    #
+    # Default: false
+    #
+    # Default: false
