thanks. but this file looks like a textbook. it is too long. can not be
shorter? I have not tried your sample but 1) will this produce farsi maths?
(2) I want irani date, is it possible? (3) From otared samples, i can see
that luatex can not handle fonts well, is the issue solved? 4) how footnote
rules are? 5) can I make a farsi presentation?6) can I create farsi
magazine? 7) does this work with beamer?
