+    Pygments
+    ~~~~~~~~
+
+    Pygments is a syntax highlighting package written in Python.
+
+    It is a generic syntax highlighter for general use in all kinds of software
+    such as forum systems, wikis or other applications that need to prettify
+    source code. Highlights are:
+
+    * a wide range of common languages and markup formats is supported
+    * special attention is paid to details, increasing quality by a fair amount
+    * support for new languages and formats are added easily
+    * a number of output formats, presently HTML, LaTeX, RTF, SVG, all image
+      formats that PIL supports, and ANSI sequences
+    * it is usable as a command-line tool and as a library
+    * ... and it highlights even Brainfuck!
+
+    The `Pygments master branch`_ is installable with ``easy_install Pygments==dev``.

+## Small explanation of the mess below :)
+#
+# The previous version of the LaTeX formatter just assigned a command to
+# each token type defined in the current style.  That obviously is
+# problematic if the highlighted code is produced for a different style
+# than the style commands themselves.
+#
+# This version works much like the HTML formatter which assigns multiple
+# CSS classes to each <span> tag, from the most specific to the least
+# specific token type, thus falling back to the parent token type if one
+# is not defined.  Here, the classes are there too and use the same short
+# forms given in token.STANDARD_TYPES.
+#
+# Highlighted code now only uses one custom command, which by default is
+# \PY and selectable by the commandprefix option (and in addition the
+# escapes \PYZat, \PYZlb and \PYZrb which haven't been renamed for
+# backwards compatibility purposes).
+#
+# \PY has two arguments: the classes, separated by +, and the text to
+# render in that style.  The classes are resolved into the respective
+# style commands by magic, which serves to ignore unknown classes.
+#
+# The magic macros are:
+# * \PY@it, \PY@bf, etc. are unconditionally wrapped around the text
+#   to render in \PY@do.  Their definition determines the style.
+# * \PY@reset resets \PY@it etc. to do nothing.
+# * \PY@toks parses the list of classes, using magic inspired by the
+#   keyval package (but modified to use plusses instead of commas
+#   because fancyvrb redefines commas inside its environments).
+# * \PY@tok processes one class, calling the \PY@tok@classname command
+#   if it exists.
+# * \PY@tok@classname sets the \PY@it etc. to reflect the chosen style
+#   for its class.
+# * \PY resets the style, parses the classnames and then calls \PY@do.
+#
+# Tip: to read this code, print it out in substituted form using e.g.
+# >>> print STYLE_TEMPLATE % {'cp': 'PY'}

+    Format tokens as LaTeX code. This needs the `fancyvrb` and `color`
+    standard packages.
+
+    Without the `full` option, code is formatted as one ``Verbatim``
+    environment, like this:
+
+    .. sourcecode:: latex
+
+        \begin{Verbatim}[commandchars=\\\{\}]
+        \PY{k}{def }\PY{n+nf}{foo}(\PY{n}{bar}):
+            \PY{k}{pass}
+        \end{Verbatim}
+
+    Wrapping can be disabled using the `nowrap` option.
+
+    The special command used here (``\PY``) and all the other macros it needs
+    are output by the `get_style_defs` method.
+
+    With the `full` option, a complete LaTeX document is output, including
+    the command definitions in the preamble.
+
+    The `get_style_defs()` method of a `LatexFormatter` returns a string
+    containing ``\def`` commands defining the macros needed inside the
+    ``Verbatim`` environments.
+
+    Additional options accepted:
+
+    `nowrap`
+        If set to ``True``, don't wrap the tokens at all, not even inside a
+        ``\begin{Verbatim}`` environment. This disables most other options
+        (default: ``False``).
+
+    `style`
+        The style to use, can be a string or a Style subclass (default:
+        ``'default'``).
+
+    `full`
+        Tells the formatter to output a "full" document, i.e. a complete
+        self-contained document (default: ``False``).
+
+    `title`
+        If `full` is true, the title that should be used to caption the
+        document (default: ``''``).
+
+    `docclass`
+        If the `full` option is enabled, this is the document class to use
+        (default: ``'article'``).
+
+    `preamble`
+        If the `full` option is enabled, this can be further preamble commands,
+        e.g. ``\usepackage`` (default: ``''``).
+
+    `linenos`
+        If set to ``True``, output line numbers (default: ``False``).
+
+    `linenostart`
+        The line number for the first line (default: ``1``).
+
+    `linenostep`
+        If set to a number n > 1, only every nth line number is printed.
+
+    `verboptions`
+        Additional options given to the Verbatim environment (see the *fancyvrb*
+        docs for possible values) (default: ``''``).
+
+    `commandprefix`
+        The LaTeX commands used to produce colored output are constructed
+        using this prefix and some letters (default: ``'PY'``).
+
+        .. versionadded:: 0.7
+        .. versionchanged:: 0.10
+           The default is now ``'PY'`` instead of ``'C'``.
+
+    `texcomments`
+        If set to ``True``, enables LaTeX comment lines.  That is, LaTex markup
+        in comment tokens is not escaped so that LaTeX can render it (default:
+        ``False``).
+
+        .. versionadded:: 1.2
+
+    `mathescape`
+        If set to ``True``, enables LaTeX math mode escape in comments. That
+        is, ``'$...$'`` inside a comment will trigger math mode (default:
+        ``False``).
+
+        .. versionadded:: 1.2
+
+    `escapeinside`
+        If set to a string of length 2, enables escaping to LaTeX. Text
+        delimited by these 2 characters is read as LaTeX code and
+        typeset accordingly. It has no effect in string literals. It has
+        no effect in comments if `texcomments` or `mathescape` is
+        set. (default: ``''``).
+
+        .. versionadded:: 2.0
+
+    `envname`
+        Allows you to pick an alternative environment name replacing Verbatim.
+        The alternate environment still has to support Verbatim's option syntax.
+        (default: ``'Verbatim'``).

+
+    `nowrap`
+        Don't wrap the SVG ``<text>`` elements in ``<svg><g>`` elements and
+        don't add a XML declaration and a doctype.  If true, the `fontfamily`
+        and `fontsize` options are ignored.  Defaults to ``False``.
+
+    `fontfamily`
+        The value to give the wrapping ``<g>`` element's ``font-family``
+        attribute, defaults to ``"monospace"``.
+
+    `fontsize`
+        The value to give the wrapping ``<g>`` element's ``font-size``
+        attribute, defaults to ``"14px"``.
+
+    `linenos`
+        If ``True``, add line numbers (default: ``False``).
+
+    `linenostart`
+        The line number for the first line (default: ``1``).
+
+    `linenostep`
+        If set to a number n > 1, only every nth line number is printed.
+        
+    `linenowidth`
+        Maximum width devoted to line numbers (default: ``3*ystep``, sufficient
+        for up to 4-digit line numbers. Increase width for longer code blocks).  
+        
+    `xoffset`
+        Starting offset in X direction, defaults to ``0``.
+
+    `yoffset`
+        Starting offset in Y direction, defaults to the font size if it is given
+        in pixels, or ``20`` else.  (This is necessary since text coordinates
+        refer to the text baseline, not the top edge.)
+
+    `ystep`
+        Offset to add to the Y coordinate for each subsequent line.  This should
+        roughly be the text size plus 5.  It defaults to that value if the text
+        size is given in pixels, or ``25`` else.
+
+    `spacehack`
+        Convert spaces in the source to ``&#160;``, which are non-breaking
+        spaces.  SVG provides the ``xml:space`` attribute to control how
+        whitespace inside tags is handled, in theory, the ``preserve`` value
+        could be used to keep all whitespace as-is.  However, many current SVG
+        viewers don't obey that rule, so this option is provided as a workaround
+        and defaults to ``True``.
