NAME

       Exporter::Easiest - Takes even more drudgery out of Exporting symbols

SYNOPSIS

       In module YourModule.pm:

	 package YourModule;
	 use Exporter::Easiest q(
	   EXPORT => :tag1
	   OK => munge frobnicate
	       :tag1 => a b c
	       :tag2 => :tag1 d e f
	   FAIL => f g h
	 );

       In other files which wish to use YourModule:

	 use ModuleName qw(frobnicate);      # import listed symbols
	 frobnicate ($left, $right)	     # calls YourModule::frobnicate

DESCRIPTION

       The Exporter::Easiest module is a wrapper around Exporter::Easy. It allows you to pass the arguments into Exporter::Easy without all those
       tiresome []s and qw()s. You pass arguments in as a string or an array of strings. You no longer need to bracket lists or take references.
       If want, you can also leave out the TAGS key and just put tag definitions along with the other keys.

       The important thing to remember is that tags should be preceded by ':' everywhere, including to the left of the '=>', otherwise it'll get
       confused.  And don't worry I haven't done something horribly pythonesque, whitespace is not significant, all the parsing logic revolves
       around the use of ':'s and '=>'s

NAME

       Exporter::Lite - Lightweight exporting of variables

SYNOPSIS

	 package Foo;
	 use Exporter::Lite;

	 # Just like Exporter.
	 @EXPORT       = qw($This That);
	 @EXPORT_OK    = qw(@Left %Right);

	 # Meanwhile, in another piece of code!
	 package Bar;
	 use Foo;  # exports $This and &That.

DESCRIPTION

       This is an alternative to Exporter intended to provide a lightweight subset of its 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. no "@ISA = qw(Exporter::Lite)" mantra).  Exporter::Lite simply
       exports its import() function.  This might be called a "mix-in".

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

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

	   @EXPORT = qw($Foo bar);

       now when you "use My::Module", $Foo and "bar()" will show up.

       In order to make exporting optional, use @EXPORT_OK.

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

	   @EXPORT_OK = qw($Foo bar);

       when My::Module is used, $Foo and "bar()" will not show up.  You have to ask for them.  "use My::Module qw($Foo bar)".

Methods
       Export::Lite has one public method, import(), which is called automaticly 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).

BUGS and CAVEATS
       Its not yet clear if this is actually any lighter or faster than Exporter.  I know its at least on par.

       OTOH, the docs are much clearer and not having to say "@ISA = qw(Exporter)" is kinda nice.
