the context tutorial has been very very informative for me indeed, the rule of thumbs also were amazing, and also I thought I would link this other page in here, it has quite a story which testifies to the end that somebody can end up in misery if they do not comprehend the contexts well enough.... http://www.stonehenge.com/merlyn/UnixReview/col38.html this has shown me about Larry Wall and I got to know him better than reading his name around and not knowing who he is/has been. Thanks every one for having given me a day of rightful resources to study, I was like blindly punching in the dark when I tried to understand contexts for I was digging in a junkyard before you guys got my back :)
