Dear, Taco and Hans

TeX-e-Parsi is better
than omega because it was written a long time ago (15 years ago) and
since then, the developer (Yazdipur) has modified and corrected the
code. So firstly I think it does not have any bugs or if it has, it has
a very small number of bugs comparing to Omega. Secondly TeX-e-Parsi
have been used by the Iranians for the whole period and still people
continue to use it and they are very happy with it since it is not
buggy at all. I believe TeX-e-Parsi is much more advanced than Omega
and it defines a set of new primitives to support LTR and RTL
typesetting fully in addition to changing some of TeX codes. It also
provides the \eqprimitive primitive so that we can define TeX primitive
commands to the appropriate Persian/Arabic names and that can be done
for any other language. So a user who does not speak English, does not
need to learn TeX's English primitive to write macros, he just can use
his language version of the primitives and at the same time the
original TeX commands will work.

Let me tell you that
unfortunately the manual is written in Persian and that does not say
anything about the actual engine, it is just Parsi LaTeX user manual.
If you intend to look at this seriously, I will be more than happy to
translate the comments in the tex.ch to English (Since the comments are
written in Persian and TeX-e-Parsi is 8 bit, you will see some strange
characters when Persian comments are present)

Just let me, if you need me to write the comments in English.

Thanks
