=head1 NAME

MooseX::App::Plugin::Config - Config files your MooseX::App applications

=head1 SYNOPSIS

In your base class:

 package MyApp;
 use MooseX::App qw(Config);
 
 option 'global_option' => (
     is          => 'rw',
     isa         => 'Int',
 );

In your command class:

 package MyApp::Some_Command;
 use MooseX::App::Command;
 extends qw(MyApp);
 
 option 'some_option' => (
     is          => 'rw',
     isa         => 'Str',
 );

Now create a config file (see L<Config::Any>) eg. a yaml file:

 ---
 global:
   global_option: 123
 some_command:
   global_option: 234
   some_option: "hello world"

The user can now call the program with a config file:

 bash$ myapp some_command --config /path/to/config.yml

=head1 METHODS

=head2 config

=head2 _config_data
