Well, it produces broken output for me:

sascha.silbe at cube:/cdtemp$ head -n 4 osm-germany-api05-070927.osm
<?xml version="1.0" encoding="UTF-8"?>
<osm version="0.5" generator="extract-polygon.pl">
   <node id="2" lat="50.1360074" lon="8.3023717" 
   <node id="104936" lat="50.0411359" lon="8.5703368" 
sascha.silbe at cube:/cdtemp$ zcat planet-api05-070927.osm.gz |head -n 8
<?xml version="1.0" encoding="UTF-8"?>
<osm version="0.5" generator="OpenStreetMap planet.rb">
   <node id="2" lat="50.1360074" lon="8.3023717" 
     <tag k="name" v="Wiesbaden-Naurod" />
     <tag k="place" v="village" />
     <tag k="is_in" v="Wiesbaden,Hesse,Germany,Europe" />
   <node id="4" lat="51.5220733" lon="-0.1458135" 
sascha.silbe at cube:/cdtemp$ zgrep '<tag' 
sascha.silbe at cube:/cdtemp$

Neither <tag>'s nor </node> has been copied to the output file. There's 
not a single <tag> inside the node file.

The version currently in SVN has some bits about relations, so I guess 
it has already been done. Haven't tested it yet, though, since it needs 
special OSM perl modules installed.

Supposed so, but currently it's unusable.
