=head1 NAME

Template::Plugin::Text::Greeking - Text::Greeking interface in Template

=head1 VERSION

This document describes Template::Plugin::Text::Greeking version 0.0.1

=head1 SYNOPSIS

In your template code.

    [% USE Text::Greeking %]

    <div id="info">
      [% Text.Greeking() %]
    </div>

=head1 DESCRIPTION

This module provides L<Text::Greeking> in your template code. Why is
it useful at all ? When you're still in design phrase of a template,
this is very useful to fill out your page so you can grok a overall
feeling. And you will be able to generate lipsums in different length
so that it can even be used for testing purpsose. (Visual testing,
which requires human testers to tell if it's successful.)

=head1 INTERFACE

=over

=item new()

This is the constructor. Which allows users to write

    [% Text.Greeking() %]

in template code.

When doing so, you may pass the several parameters to tweak
greeking class' output. Such as:

    [% Text.Greeking(paragraphs => [1,5]) %]

The available options keys are "words", "sentences", and "paragraphs".
The value to these 3 keys should be an array (in the notation of array
ref) of 2 numbers. The first number means the minium, the second of
maximum. The example above is just the same as:

    my $greeing = Text::Greeking->new;
    $greeking->paragraphs(1,5);

Additionally, you may use alternative greeking classes in different
languages. So far the only alternative option is Chinese. In this case
you would say:

    [% Text.Greeking(lang => "zh_TW") %]

To use L<Text::Greeking::zh_TW> to generate Chinese lipsums.
