  =head1 NAME
  
  Template::TT3::Constants - defines constants for other TT modules
  
  =head1 SYNOPSIS
  
      use Template::TT3::Constants;
  
      # TODO
  
  =head1 DESCRIPTION
  
  This module defines a number of constants used by other modules in the
  Template Toolkit.  They can be used by specifying the
  Template::Constants package explicitly as part of the name:
  
      use Template::TT3::Constants;
  
      $chomp = Template::TT3::Constants::CHOMP_ALL;
  
  Constants may be imported into the caller's namespace by naming them as 
  options to the C<use Template::TT3::Constants> statement:
  
      use Template::TT3::Constants qw( CHOMP_ALL );
  
      $chomp = CHOMP_ALL;
  
  Alternatively, one of the tagset identifiers may be specified
  to import different sets of constants.
  
      use Template::TT3::Constants qw( :chomp );
  
      $chomp = CHOMP_ALL;
  
  =head1 EXPORTABLE TAG SETS
  
  The following tag sets and associated constants are defined: 
  
    :exception        # constants relating to exception handling
      TYPE            # 0 - first field of Template::TT3::Exception
      INFO            # 1 - second field
      TEXT            # 2 - third field 
  
    :all         All the above constants.
