Ouch. Well I can't hide behind the language card after demonstrating
that I'm rather able to write in english on the mailing list. The
assumption is: if you use environment.hpp you already no what this is
supposed to do, since you read the OS documentation. The reason for that
is that I was familiar with this stuff when I started to use
boost.process 0.5. If you know that much, I think the documentation does
suffice. But I would also be insincere if I claimed that writing
documentation is my favorite thing in the world.
But since this was now critized by many, I will add a chapter explaining
all those concepts, i.e. pipes, environment, process groups and a bit of
