Phobos Contributor Tutorial

[via Digitalmars-d]

Hi,

with one phobos PR accepted any a second one submitted, I feel it 
is about time I write a tutorial. No, seriously, I spend some 
time to get started. Others might have a rough time, too. So here 
is a draft of a contributor tutorial. Posix based.

All of it is taken from the wiki, of course.
