Sorry, I know I'm boring...

Now I discovered I have substantially only one latin ttf font on my  
machine among the huge amount of fonts...
Doulos SIL which file is DoulosSILR

So, I'm testing with the type-doulos.tex file containg this
\starttypescript [serif] [doulos]
\setups[font:fallback:roman]
\definefontsynonym [Serif] [Doulos SIL]
\stoptypescript

\starttypescript [serif] [doulos]
\definefontsynonym [Doulos SIL] [file:DoulosSILR][features=default]
\stoptypescript

\starttypescript [doulos]
\definetypeface [doulos] [rm] [roman] [doulos] [default]
\stoptypescript

But does not work.
The fact is probably that I'm not really understanding what's going  
on here.
I was reading some of the resources here:
http://wiki.contextgarden.net/Fonts
e.g. Thomas' article.
http://tug.org/pracjourn/2005-2/schmitz/schmitz.pdf

The problem is that I would probably need this (as suggested once by  
Aditya):
http://wiki.contextgarden.net/Understanding_how_fonts_work_in_ConTeXt
but it's pretty incomplete.

I've also looked at
http://www.pragma-ade.com/general/manuals/mfonts.pdf
but cannot really follow it.

Could anyone comment this famous piece of code?
http://wiki.contextgarden.net/Mark_IV#A_.28Complete. 
29_Typescript_Example
I'd like to add infos to the wiki


Thanks

Best

I did this interview where I just mentioned that I read Foucault. Who  
doesn't in university, right? I was in this strip club giving this  
guy a lap dance and all he wanted to do was to discuss Foucault with  
me. Well, I can stand naked and do my little dance, or I can discuss  
Foucault, but not at the same time; too much information.
