[texhax] bidirectional two columns

[Yanir Rubinstein]

Dear Sirs,

I am writing a book in Hebrew, using TeX--XeT and am trying to typeset
in two columns. The same procedure that works in usual English files in 
TeX produces the the columns reversed, that is the first one appears on 
the left while the second appears on the right.

Do you know of a package/macros for multi-column printing for 
right-to-left editing?

My sincere thanks, Yanir Rubinstein
