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

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