seeking 'hello world' example for Arabic typesetting with conTeXt

[Jon Crump <jjcrump@uw.edu>]

Dear all,

I'm gradually getting my head around using ConTeXt to typeset texts
marked up in TEI/XML. I'm trying to typeset an English/Arabic text and
I keep breaking my teeth on the Arabic. I'm trying to do what I can
with the macTeX 2010 distribution, but the documentation on the
conTeXt wiki has me confused. The amount I don't know about TeX is
truly daunting, but clearly there are some basic things about font
management that I don't understand.

I thought I had found a minimal example in
http://wiki.contextgarden.net/Arabic_and_Hebrew that I could use as a
starting point. After saving it locally as ara-sty.tex I tried to
typeset:

% engine=luatex
\environment ara-sty
\starttext
\setarabic

أهلا بالعالم!
\stoptext

a PDF was produced but it contained no text save for !. Among the
things that conTeXt told me was:

!define font    : font with name arabtype is not found
!define font    : unknown font arabtype, loading aborted
!define font    : unable to define arabtype as \*Arabic20ptrmtf*

Where should I look for this font? Where is conTeXt looking for it? If
I were to find it, where should I put it? I gather that fonts on my
system can be used, but font metric files for them have to be
generated. How to do that?

Apologies for the unfocused tyro questions, but the TeX world has
become so much larger than it was when I last used it that I feel
quite at sea with all the available documentation.

thanks,
Jon
