The Template::Constants modules defines, and optionally exports into the caller's namespace, a number of constants used by the Template package.
Constants may be used by specifying the Template::Constants package explicitly:
use Template::Constants;
print Template::Constants::STATUS_DECLINED;
Constants may be imported into the caller's namespace by naming them as 
options to the 'use Template::Constants' statement:
use Template::Constants qw( STATUS_DECLINED );
print STATUS_DECLINED;
Alternatively, one of the following tagset identifiers may be specified to import sets of constants; :status, :error, :all.
use Template::Constants qw( :status );
print STATUS_DECLINED;
See [% ttlink('Exporter') -%] for more information on exporting variables.
