=head1 NAME

HiD::Generator::ArchivePage - Archive page generator

=head1 DESCRIPTION

This Generator produces an archive page of all your posts.

Enable it by setting the 'archive_page.generate' key in your config to true
and the 'archive_page.layout' key to the path with the layout for the archive
page. You can also set 'archive_page.url' to the URL where the page should be
published to, or let it default to the site-wide destination. Finally,
'archive_page.destination' can be used to set a destination directory.
