Re: Very small X for embedded systems

Hello Koen,

I did not yet recognized twin, it looks like an alternative to kdrive, right?
And diet-X11 should be used as the depended xlib, but I don't find many informations using google.

Can you send me a link to diet-X11?

It sounds good, what you have written. Let's see where it goes to :)

Greetings,
Jonatan
