 Set this to C<0> to turn off all POD generation.
 
+=head2 pod_comment_mode
+
+Controls where table comments appear in the generated POD. By default table
+comments are appended to the C<NAME> section of the documentation. You can
+force a C<DESCRIPTION> section to be generated with the comment instead, or
+choose the length threshold at which the comment is forced into the
+description.

+  pod_comment_mode => 'name' # default behaviour
+  pod_comment_mode => 'description' # force creation of DESCRIPTION section
+  pod_comment_mode => 'auto' # use description if length > pod_comment_spillover_length
+
+=head2 pod_comment_spillover_length
+
+When pod_comment_mode is set to C<auto>, this is the length of the comment at
+which it will be forced into a separate description section.
+
+The default is C<60>
