When I tried to run this file under luatex it blew up on the \jobname. So I defined \jobname to be the name of the file and it blew up again, treating \jobname as a module. Clearly I am misunderstanding something. Please educate me a bit further. What is \jobname? I am running plain luatex, not Context or lualatex. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html
