.SH "NAME"
Template::Constants \- Defines constants for the Template Toolkit
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&    use Template::Constants qw( :status :error :all );
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`Template::Constants\*(C'\fR modules defines, and optionally exports into the
caller's namespace, a number of constants used by the Template package.
.PP
Constants may be used by specifying the \f(CW\*(C`Template::Constants\*(C'\fR package
explicitly:
.PP
.Vb 2
\&    use Template::Constants;
\&    print Template::Constants::STATUS_DECLINED;
.Ve
.PP
Constants may be imported into the caller's namespace by naming them as
options to the \f(CW\*(C`use Template::Constants\*(C'\fR statement:
.PP
.Vb 2
\&    use Template::Constants qw( STATUS_DECLINED );
\&    print STATUS_DECLINED;
.Ve
.PP
Alternatively, one of the following tagset identifiers may be specified
to import sets of constants: '\f(CW\*(C`:status\*(C'\fR', '\f(CW\*(C`:error\*(C'\fR', '\f(CW\*(C`:all\*(C'\fR'.
.PP
.Vb 2
\&    use Template::Constants qw( :status );
\&    print STATUS_DECLINED;
.Ve
.PP
Consult the documentation for the \f(CW\*(C`Exporter\*(C'\fR module for more information
on exporting variables.
