+    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 tip`_ is installable with ``easy_install Pygments==dev``.

+USAGE = """\
+Usage: %s [-l <lexer> | -g] [-F <filter>[:<options>]] [-f <formatter>]
+          [-O <options>] [-P <option=value>] [-s] [-v] [-o <outfile>] [<infile>]
+
+       %s -S <style> -f <formatter> [-a <arg>] [-O <options>] [-P <option=value>]
+       %s -L [<which> ...]
+       %s -N <filename>
+       %s -H <type> <name>
+       %s -h | -V
+
+Highlight the input file and write the result to <outfile>.
+
+If no input file is given, use stdin, if -o is not given, use stdout.
+
+If -s is passed, lexing will be done in "streaming" mode, reading and
+highlighting one line at a time.  This will only work properly with
+lexers that have no constructs spanning multiple lines!
+
+<lexer> is a lexer name (query all lexer names with -L). If -l is not
+given, the lexer is guessed from the extension of the input file name
+(this obviously doesn't work if the input is stdin).  If -g is passed,
+attempt to guess the lexer from the file contents, or pass through as
+plain text if this fails (this can work for stdin).
+
+Likewise, <formatter> is a formatter name, and will be guessed from
+the extension of the output file name. If no output file is given,
+the terminal formatter will be used by default.
+
+With the -O option, you can give the lexer and formatter a comma-
+separated list of options, e.g. ``-O bg=light,python=cool``.
+
+The -P option adds lexer and formatter options like the -O option, but
+you can only give one option per -P. That way, the option value may
+contain commas and equals signs, which it can't with -O, e.g.
+``-P "heading=Pygments, the Python highlighter".
+
+With the -F option, you can add filters to the token stream, you can
+give options in the same way as for -O after a colon (note: there must
+not be spaces around the colon).
+
+The -O, -P and -F options can be given multiple times.
+
+With the -S option, print out style definitions for style <style>
+for formatter <formatter>. The argument given by -a is formatter
+dependent.
+
+The -L option lists lexers, formatters, styles or filters -- set
+`which` to the thing you want to list (e.g. "styles"), or omit it to
+list everything.
+
+The -N option guesses and prints out a lexer name based solely on
+the given filename. It does not take input or highlight anything.
+If no specific lexer can be determined "text" is returned.
+
+The -H option prints detailed help for the object <name> of type <type>,
+where <type> is one of "lexer", "formatter" or "filter".
+
+The -s option processes lines one at a time until EOF, rather than
+waiting to process the entire file.  This only works for stdin, and
+is intended for streaming input such as you get from 'tail -f'.
+Example usage: "tail -f sql.log | pygmentize -s -l sql"
+
+The -v option prints a detailed traceback on unhandled exceptions,
+which is useful for debugging and bug reports.
+
+The -h option prints this help.
+The -V option prints the package version.
