what is a "pile" of bytes?

only in your imagination, karl.

karl, why in god's name are you writing documentation ostensibly to
help others do things that you haven't even verified yourself?
please, karl, do everyone a favour, and stop trying to do them any
more favours.  all you're going to do is lead someone into doing
something disastrously disastrous.

and please, karl, for the last time, get a blog where you can publish
all this incorrect and potentially damaging guidance.  the amount of
everyone's time you've wasted in "finally" producing documentation
that is still incorrect is really quite breathtaking.
