=head1 NAME

Perinci::CmdLine::Any - Choose Perinci::CmdLine implementation (::Lite or ::Classic)

=head1 VERSION

This document describes version 0.152 of Perinci::CmdLine::Any (from Perl distribution Perinci-CmdLine-Any), released on 2021-06-23.

=head1 SYNOPSIS

In your command-line script (this will pick ::Lite first):

 #!perl
 use Perinci::CmdLine::Any;
 Perinci::CmdLine::Any->new(url => '/Package/func')->run;

In your command-line script (this will pick ::Classic first, and falls back to
::Lite):

 #!perl
 use Perinci::CmdLine::Any -prefer_lite=>0;
 Perinci::CmdLine::Any->new(url => '/Package/func')->run;

=head1 DESCRIPTION

This module lets you use L<Perinci::CmdLine::Lite> or
L<Perinci::CmdLine::Classic>.

If you want to force using a specific class, you can set the
C<PERINCI_CMDLINE_ANY> environment variable, e.g. the command below will only
try to use Perinci::CmdLine::Classic:

 % PERINCI_CMDLINE_ANY=Perinci::CmdLine::Classic yourapp.pl
 % PERINCI_CMDLINE_ANY=classic yourapp.pl

If you want to prefer to Perinci::CmdLine::Classic (but user will still be able
to override using C<PERINCI_CMDLINE_ANY>):

 use Perinci::CmdLine::Any -prefer_lite => 0;
