> As you can see in TeX-e-Parsi we can have automatic direction
change.
The fact automatic direction change is hardcoded is a
serious
drawback, and not and advantage, imo. There are many subtle
points in bidi typesetting which
can be addressed only in a
programmable environment, like that provided by luatex. Even
with otps, which are very limited as compared with
luatex, I
managed to implement a preliminary automatic
direction change
(in fact, an automatic script
change, including direction).
