__DATA__

=head1 NAME 

Kwiki::GoogleLink - easy links to Google searches

=head1 SYNOPSIS

 $ cpan Kwiki::GoogleLink
 $ cd /path/to/kwiki
 $ echo "Kwiki::GoogleLink" >> plugins
 $ kwiki -update

=head1 DESCRIPTION

This was written as a demonstration of a plugin to add a new WAFL
phrase to the Kwiki formatting rules.

This plugin makes it quick and easy to add a Google search link to a
Kwiki page, for example:

    Search Google for: {google:Kwiki}

will be rendered as

    Search Google for: <a href="http://www.google.com/search?q=Kwiki">Kwiki</a>

This example can be used as the basis for custom shortcuts at your own
site.
