=head1 NAME
Perinci::CmdLine::dux - Perinci::CmdLine subclass for dux cli
=head1 VERSION
This document describes version 1.53 of Perinci::CmdLine::dux (from Perl distribution App-dux), released on 2017-07-10.
=head1 DESCRIPTION
This subclass sets C<in> and C<out> arguments for the dux function, and displays
the resulting <out> array.
It also add a special flag function argument C<< -dux_cli => 1 >> so the
function is aware it is being run through the dux CLI application.
