+=head1 NAME
+
+Feed::Role::ContentOnly - extract and sanitize HTML content from a
+feed body
+
+=head1 SYNOPSIS
+
+    set_feed_class(Feed->with_traits(
+        'Mail',
+        'LinkedPage',
+        'ContentOnly',
+    ));
+
+If your feed only has summaries or only the first paragraph, maybe you
+want to fetch the complete HTML page for processing. This strips out
+the sidebars and sanitizes the HTML to look sane by using
+L<HTML::ExtractMain>.
