I know.  I never argued that it was.  You must've misunderstood me..

My point exactly, a whole lot of them actually uses redefinitions for
something purposeful.

Mmh.  Yes.

Wrong - to inform regular users that the config file is not in the
syntax that they (anyone) would expect.

Ah, "almost", now you're just poking me in the eye for the fun of it.
Don't do that...

Ah, if it's documented, fair enough then.
But alas...

"Python setup script" in no way implies that the script is a "Python script".

"Python script used to setup domains by 'xm create'" would have, but
that's not what it says.

Again, the above in no way implies that the file itself is a Python script.

That's not good enough.  You cannot expect newbies to dig in to the
most complicated features / configurations of a system just to get to
know how to achieve the basics.

No, you're wrong.
