Syntax:

Where:
--help
show this help message.
--us-ascii
if specified, the output will contain only US-ASCII characters.
--languages(or --language)
export only the specified language codes.
Separate languages with commas; you can also use this argument
more than once; it's case insensitive and accepts both '_' and
'-' as locale chunks separator (eg we accept 'it_IT' as well as
'it-it').
--reduce
if set to yes the output won't contain languages with the same
base language and rules.
For instance nl_BE ('Flemish') will be omitted because it's the
same as nl ('Dutch').
Defaults to 'no' if --languages is specified, to 'yes' otherwise.
--parenthesis
if set to no, extra parenthesis will be omitted in generated
plural rules formulas.
Those extra parenthesis are needed to create a PHP-compatible
formula.
Defaults to 'yes'
--output
if specified, the output will be saved to <file name>. If not
specified we'll output to standard output.
