Ups, sorry, sent this to Carsten rather than to the list.
Forgot to say I was looking at the on-line docs @ http://www.xfree86.org/current before yesterday, and found many of the html docs are not redeable, you cannot see carriage returns at the beginning in some of them.
Kind Regards,
Note: forwarded message attached.

Hi there,
Well, many thanks for all your replies.
Carsten, actually, somewhere from my ignorance, I do agree with that.
Is that clear there are better low-level ways to handle the config of an application via external-file.
But at the same time, I've always though markup language (I'm not talking about sgml or xml itself),
is just the most efficient way humans can interact with computers for this kind of things, or many others much more complicated i.e.: writting books without leaving your eyes on a troff/tex based syntax, which looks quite confusing to me, and not designed for humans at all.
Apart from the time I'll save (which I need) trying to implement some sort of parser, the point on using markup is the way the final user is gonna handle the app.
Most of times, you just need read either contents or tags within a markup file to guess what's all about. From my point of view, anybody would be ab le to configure my app even haven't seen a markup file ever before.
Apart from that, It's ok that you don't need an external library for parsing a file, but from the very moment you are based on an on-disk config file, you'll find the same problem again, carriage returns, some inline formatting you may need i.e. sentences inside brackets, etc.
Whether you would be on development of a proffesional app. What's the point on implementing a config syntax where the user's gonna need to spend more time reading your specs than actually tunning the appl itself?
Kind Regards,

xml config, while human readable and extendible, is
1. "bloated" for disk space needs.
2. is very inefficient at inlining binary data (eg you want to inline the pixel
data for an icon along with metadata) 3. is actually very slow for a computer
to parse, compared to much mroe simplistic binary config. everything needs to
be parsed and checked as it needs to handle escapes, freeformt formatting etc.
i'm not a fan of xml myself :)

yes. but it isn't the most efficient way to do it. :) anyway - stick with what
you have.

never tried - but i have used xrender directly and it does work. mind you
beware you are likely to find performance issues with xrender. they may vary
from neglegible to dysmally slow, sometimes it may be fast. sometimes.
