preliminary text

Hi all, I wrote a preliminary text about therion on "english" It is not finished, but I would get some feedback. So, if you have a little bit of spare time, you could visit http://www.infonegocio.com/tatel/therion_for_cavers.txt and drop a word about it on the list. Gramatical corrections will be welcome ;-) I know, this will be on wiki... when finished. Cheers, Roman
