The only thing I see in the readme refers to:
"I added the FIA's garage replacing the 11th team then everybody can replace it by your own team. Just replace this files for:
GARAGE:
melbourne2001_page_252.tex
melbourne2001_page_253.tex"
These tex files are the two Jaguar garage walls. If those are changed to "Arrows" then what do we do with Jaguar? Still only 10 teams. The garage further down pit lane from Minardi is Parc Ferme with only one door opened and the others closed.
