NAME
       Template::Config - Factory module for instantiating other TT2 modules

SYNOPSIS
	   use Template::Config;

DESCRIPTION
       This module implements various methods for loading and instantiating other modules that
       comprise the Template Toolkit.  It provides a consistent way to create toolkit components
       and allows custom modules to be used in place of the regular ones.

       Package variables such as $STASH, $SERVICE, $CONTEXT, etc., contain the default
       module/package name for each component (Template::Stash, Template::Service and
       Template::Context, respectively) and are used by the various factory methods (stash(),
       service() and context()) to load the appropriate module. Changing these package variables
       will cause subsequent calls to the relevant factory method to load and instantiate an
       object from the new class.

PUBLIC METHODS
   load($module)
       Load a module using Perl's require(). Any occurences of '"::"' in the module name are be
       converted to '"/"', and '".pm"' is appended. Returns 1 on success or undef on error.  Use
       "$class->error()" to examine the error string.

   preload()
       This method preloads all the other "Template::*" modules that are likely to be used. It is
       called automatically by the Template module when running under mod_perl ($ENV{MOD_PERL} is
       set).

   parser(\%config)
       Instantiate a new parser object of the class whose name is denoted by the package variable
       $PARSER (default: Template::Parser).  Returns a reference to a newly instantiated parser
       object or undef on error.

   provider(\%config)
       Instantiate a new template provider object (default: Template::Provider).  Returns an
       object reference or undef on error, as above.

   plugins(\%config)
       Instantiate a new plugins provider object (default: Template::Plugins).	Returns an object
       reference or undef on error, as above.

   filters(\%config)
       Instantiate a new filter provider object (default: Template::Filters).  Returns an object
       reference or undef on error, as above.

   stash(\%vars)
       Instantiate a new stash object (Template::Stash or Template::Stash::XS depending on the
       default set at installation time) using the contents of the optional hash array passed by
       parameter as initial variable definitions.  Returns an object reference or undef on error,
       as above.

   context(\%config)
       Instantiate a new template context object (default: Template::Context).	Returns an object
       reference or undef on error, as above.

   service(\%config)
       Instantiate a new template service object (default: Template::Service).	Returns an object
       reference or undef on error, as above.

   iterator(\%config)
       Instantiate a new template iterator object (default: Template::Iterator).  Returns an
       object reference or undef on error, as above.

   constants(\%config)
       Instantiate a new namespace handler for compile time constant folding (default:
       Template::Namespace::Constants). Returns an object reference or undef on error, as above.

   instdir($dir)
       Returns the root directory of the Template Toolkit installation under which optional
       components are installed.  Any relative directory specified as an argument will be
       appended to the returned directory.

	   # e.g. returns '/usr/local/tt2'
	   my $ttroot = Template::Config->instdir()
	       || die "$Template::Config::ERROR\n";

	   # e.g. returns '/usr/local/tt2/templates'
	   my $template = Template::Config->instdir('templates')
	       || die "$Template::Config::ERROR\n";

       Returns "undef" and sets $Template::Config::ERROR appropriately if the optional components
       of the Template Toolkit have not been installed.
