Working flow of Nginx startup phase

A big picture described nginx startup working flow from 'main' invoked to event-loop started.

For people who had written one or more nginx modules and wanna digg a bit more to see what happens while nginx starts up.

Althrough not any piece of detail nginx does is shown here, I hope this image may help if you are tired searching something through source codes tree.

This image might be a bit larger than your screen I think : |...
