 Create a new Smokeping::Info instance. Instantiating Smokeping::Info entails
 reading the configuration file. This is a compte heavy procedure. So you may
 want to use a single info object to handle multiple requests.
 
-=head3 fetch_nodes(pattern=>'/...',mode=>{recursive|regexp})
+=head2 fetch_nodes(pattern=>'/...',mode=>{recursive|regexp})
 
 The fetch_nodes method will find all nodes sitting in the given pattern
 (absolute path) including the path itself. By setting the recursive mode,
 all rrd files in paths below will be returned as well. In regexp mode, all
 rrd paths matching the given expression will be returned.
 
-=head3 stat_node(node,start,end)
+=head2 stat_node(node,start,end)
 
 Return a hash pointer to statistics based on the data stored in the given
 rrd path.
