the very core of mac os x...

[maccatalan]

Hi.

I would like to download the sources of Darwin. However when I go on the download web page of the Apple Darwin Project, there are plenty of files ...

I supose I don't need to download the PS2 Mouse files for example.

So my question is quite simple :

which files should I download (and thanks for helping me because I searched and I am lost right now) to get a minimal OS running on my mac after compiling the files ... and as bonus question : how to compile them ?

NB: the goal is to try to modify (as an exercice an elementary and minimal OS for my Mac in order to learn as much as I can about experimental OS programming).

Thank you very much for your help.
Pierre.

NB: I went on Building Darwin HOWTO but this did not help me so much ... that's why I post here hoping someone will post a clear and human understandable reply

thx again,
Pierre.
