NAME
       Exporter::Lite - lightweight exporting of functions and variables

SYNOPSIS
         package Foo;
         use Exporter::Lite;

         our @EXPORT    = qw($This That);      # default exports
         our @EXPORT_OK = qw(@Left %Right);    # optional exports

       Then in code using the module:

         use Foo;
         # $This and &That are imported here

       You have to explicitly ask for optional exports:

        use Foo qw/ @Left %Right /;

DESCRIPTION
       Exporter::Lite is an alternative to Exporter, intended to provide a lightweight subset of
       the most commonly-used functionality.  It supports "import()", @EXPORT and @EXPORT_OK and
       not a whole lot else.

       Unlike Exporter, it is not necessary to inherit from Exporter::Lite; Ie you don't need to
       write:

        @ISA = qw(Exporter::Lite);

       Exporter::Lite simply exports its import() function into your namespace.  This might be
       called a "mix-in" or a "role".

       Setting up a module to export its variables and functions is simple:

           package My::Module;
           use Exporter::Lite;

           our @EXPORT = qw($Foo bar);

       Functions and variables listed in the @EXPORT package variable are automatically exported
       if you use the module and don't explicitly list any imports.  Now, when you "use
       My::Module", $Foo and "bar()" will show up.

       Optional exports are listed in the @EXPORT_OK package variable:

           package My::Module;
           use Exporter::Lite;

           our @EXPORT_OK = qw($Foo bar);

       When My::Module is used, $Foo and "bar()" will not show up, unless you explicitly ask for
       them:

           use My::Module qw($Foo bar);

       Note that when you specify one or more functions or variables to import, then you must
       also explicitly list any of the default symbols you want to use.  So if you have an
       exporting module:

           package Games;
           our @EXPORT    = qw/ pacman defender  /;
           our @EXPORT_OK = qw/ galaga centipede /;

       Then if you want to use both "pacman" and "galaga", then you'd write:

           use Games qw/ pacman galaga /;

Methods
       Export::Lite has one public method, import(), which is called automatically when your
       modules is use()'d.

       In normal usage you don't have to worry about this at all.

       import
             Some::Module->import;
             Some::Module->import(@symbols);

           Works just like "Exporter::import()" excepting it only honors @Some::Module::EXPORT
           and @Some::Module::EXPORT_OK.

           The given @symbols are exported to the current package provided they are in
           @Some::Module::EXPORT or @Some::Module::EXPORT_OK.  Otherwise an exception is thrown
           (ie. the program dies).

           If @symbols is not given, everything in @Some::Module::EXPORT is exported.

DIAGNOSTICS
       '"%s" is not exported by the %s module'
           Attempted to import a symbol which is not in @EXPORT or @EXPORT_OK.

       'Can\'t export symbol: %s'
           Attempted to import a symbol of an unknown type (ie. the leading $@% salad wasn't
           recognized).

SEE ALSO
       Exporter is the grandaddy of all Exporter modules, and bundled with Perl itself, unlike
       the rest of the modules listed here.

       Attribute::Exporter defines attributes which you use to mark which subs and variables you
       want to export, and how.

       Exporter::Simple also uses attributes to control the export of functions and variables
       from your module.

       Const::Exporter makes it easy to create a module that exports constants.

       Constant::Exporter is another module that makes it easy to create modules that define and
       export constants.

       Sub::Exporter is a "sophisticated exporter for custom-built routines"; it lets you provide
       generators that can be used to customise what gets imported when someone uses your module.

       Exporter::Tiny provides the same features as Sub::Exporter, but relying only on core
       dependencies.

       Exporter::Shiny is a shortcut for Exporter::Tiny that provides a more concise notation for
       providing optional exports.

       Exporter::Declare provides syntactic sugar to make the export status of your functions
       part of their declaration. Kind of.

       AppConfig::Exporter lets you export part of an AppConfig-based configuration.

       Exporter::Lexical lets you export lexical subs from your module.

       Constant::Export::Lazy lets you write a module that exports function-style constants,
       which are instantiated lazily.

       Exporter::Auto will export everything from your module that it thinks is a public function
       (name doesn't start with an underscore).

       Class::Exporter lets you export class methods as regular subroutines.

       Xporter is like Exporter, but with persistent defaults and auto-ISA.
