-USAGE = """\
-Usage: %s [-l <lexer> | -g] [-F <filter>[:<options>]] [-f <formatter>]
-          [-O <options>] [-P <option=value>] [-s] [-v] [-x] [-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.
-
-The additional option -x allows custom lexers and formatters to be
-loaded from a .py file relative to the current working directory. For
-example, ``-l ./customlexer.py -x``. By default, this option expects a
-file with a class named CustomLexer or CustomFormatter; you can also
-specify your own class name with a colon (``-l ./lexer.py:MyLexer``).
-Users should be very careful not to use this option with untrusted files,
-because it will import and run them.
-
-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.
