Building instruction

[Pietro]

Hi everybody,

I would be interested in building the project from the sources and I
have checked out the nginx source code following the instruction:

http://nginx.org/en/docs/configure.html

I can't figure out where I should start, in fact I do not see a
configure script at the top level, quite naively this is what I have
done :

cd auto
./configure --sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid
./configure: 10: .: Can't open auto/options

I have the feeling I am getting it all wrong but I can't find clearer
building instruction, how do I build NGINX ? Have I missed some crucial
docs present in the website or inside the source repo itself ?

Cheers,
Pietro
