ok, I am trying - by far the best outcome is if I convert the file from latex to xhtml: problem is, after I have done so I do not know how to transfer the file to the device: calibre wants to convert it to epub (with awful results), and if I copy both the file itself and the .css one, the device cannot see it. I know this must be something very silly, but I cannot figure it out: perhaps I should rename the .xhtml extension (to xtm perhaps?)?
