Thank you with my former colleagues (now collaborator) in the conspiracy for matter chart of STAGE, in particular Rafal Ksiezyk, Graham Moore and Hans Holger Rath, of much of discussions inspiring; in Geir Ove Grnmo and Lars Marius Garshol to develop all the way of software of matter chart so that I play with; with the writers of the standard of matter chart, of Steve Newcomb, Martin Bryan and particularly of Michel Biezunski, and all the others implied in its development, to do a so excellent work; and with Sylvia Schwab for its council and encouragement.
