Usage: /usr/local/bin/pygmentize [-l <lexer> | -g] [-F <filter>[:<options>]] [-f <formatter>]
          [-O <options>] [-P <option=value>] [-o <outfile>] [<infile>]

       /usr/local/bin/pygmentize -S <style> -f <formatter> [-a <arg>] [-O <options>] [-P <option=value>]
       /usr/local/bin/pygmentize -L [<which> ...]
       /usr/local/bin/pygmentize -N <filename>
       /usr/local/bin/pygmentize -H <type> <name>
       /usr/local/bin/pygmentize -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.

<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 -h option prints this help.
The -V option prints the package version.
