=head1 NAME

HiD::Generator::TagPages - Example generator to create tagged pages


This is an example of a generator plugin. It generates one page per key in the
C<< $site->tags >> hash, and injects that page into the site so that it will
be published.

To activate this plugin, add a 'tags.generate' key to your config. You should
also add a 'tags.layout' key that provides a template file to use. Finally,
you may also set a 'tags.destination' key to indicate an output directory for
the tag files. If this is not set, it will default to the normal site-wise
