No worries. I meant to say, there were some minor differences between your patch 15 adding the documentation and Claudio's version. If you want those differences applied please send me an incremental patch. cheers

The differences are because I had a slightly older version at the time I posted my patches. -- Thiago Jung Bauermann IBM Linux Technology Center
