NAME
       Package::Constants - List all constants declared in a package

SYNOPSIS
           use Package::Constants;

           ### list the names of all constants in a given package;
           @const = Package::Constants->list( __PACKAGE__ );
           @const = Package::Constants->list( 'main' );

DESCRIPTION
       "Package::Constants" lists all the constants defined in a certain package. This can be
       useful for, among others, setting up an autogenerated "@EXPORT/@EXPORT_OK" for a
       Constants.pm file.

CLASS METHODS
   @const = Package::Constants->list( PACKAGE_NAME );
       Lists the names of all the constants defined in the provided package.

GLOBAL VARIABLES
   $Package::Constants::DEBUG
       When set to true, prints out debug information to STDERR about the package it is
       inspecting. Helps to identify issues when the results are not as you expect.

       Defaults to false.
