NAME
    Const::Exporter - Declare constants for export.

SYNOPSIS
    Define a constants module:

      package MyApp::Constants;

      use Const::Fast;

      our $zoo => 1234;

      use Const::Exporter

         tag_a => [                  # use MyApp::Constants /:tag_a/;
            'foo'  => 1,             # exports "foo"
            '$bar' => 2,             # exports "$bar"
            '@baz' => [qw/ a b c /], # exports "@baz"
            '%bo'  => { a => 1 },    # exports "%bo"
         ],

         tag_b => [                  # use MyApp::Constants /:tag_b/;
            'foo',                   # exports "foo" (same as from ":tag_a")
            '$zoo',                  # exports "$zoo" (as defined above)
         ];

      # `use Const::Exporter` can be specified multiple times

      use Const::Exporter

         tag_b => [                 # we can add symbols to ":tab_b"
            'moo' => $bar,          # exports "moo" (same value as "$bar")
         ],

         enums => [

           [qw/ goo gab gub /] => 0, # exports enumerated symbols, from 0..2

         ],

         default => [qw/ fo $bar /]; # exported by default

    and use that module:

      package MyApp;

      use MyApp::Constants qw/ $zoo :tag_a /;

      ...

DESCRIPTION
    This module allows you to declare constants that can be exported to
    other modules.

SEE ALSO
    See Exporter for a discussion of export tags.

  Similar Modules
    Exporter::Constants
        This module only allows you to declare function symbol constants,
        akin to the constant module, without tags.

    Constant::Exporter
        This module only allows you to declare function symbol constants,
        akin to the constant module, although you can specify tags.

    Constant::Export::Lazy
        This module only allows you to declare function symbol constants,
        akin to the constant module by defining functions that are only
        called as needed. The interface is rather complex.
