# 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' );

        ### enable debugging output
        $Package::Constants::DEBUG = 1;

# 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.
