Hi Pipers, I thought to myself I rather should give the good example and wrote some more in the design proposal ;) Filled in the DL and BL alinea's. All the DL text I copied out of Brad's document @ http://www.bioinformatics.org/piper/documentation/dl_info.pdf. The BL text is new. For all convenience the doc is available in Piper's cvs repository, or for all you hard core techies it's attached. jarl -------------- next part -------------- An HTML attachment was scrubbed...
