+=head1 NAME
+
+uf_adr_meta - plugin to create an 'adr' microformat tag from post
+metadata
+
+=head1 DESCRIPTION
+
+uf_adr_meta is a plugin to create an 'adr' microformat tag from metadata
+in your post. The microformat tag is created in the $uf_adr_meta::adr
+variable for use in templates or by other plugins, or if the
+'auto_append_to_body' config variable is set (it is by default),
+uf_adr_meta will append the tag to your story body automatically.
+
+=head2 OPTIONAL METADATA ITEMS
+
+=over 4
+
+=item post-office-box (alt: pobox)
+
+=item extended-address
+
+=item street-address (alt: street)
+
+=item locality (alt: city)
+
+=item region (alt: state)
+
+=item country-name (alt: country)
+
+=back
+
+=head2 Config Elements
+
+uf_adr_meta also supports a couple of config elements that can be used to
+override plugin config data on a per-story basis:
+
+=over 4
+
+=item Adr-Class (metamail) / adr_class (meta)
+
+This class (or list of classes) is appended to the class list applied to the
+top-level adr element in the rendered adr i.e. it overrides the
+'class' config variable.
+
+=item Adr-Autoappend (metamail) / adr_autoappend (meta)
+
+This is a flag (0 or 1) indicating whether the rendered adr should be
+automatically appended to the story body. It overrides the 'auto_append_to_body'
+config variable.
+
+=item Adr-Style (metamail) / adr_style (meta)
+
+One of the following styles: 'div-span', 'ul', 'dl', used to render the adr.
+It overrides the 'style' config variable.
+
+=back
+
+=head1 USAGE
+
+uf_adr_meta should be loaded after the meta plugins (meta
+itself, or the metaclear/metamail/metadir/metafile family).
