Please run it one more time Mr. DJ:

Do I really need to explain this one to you? Do I?

Bahhh, ok, here we go:

Previously alluded to script can easily be made to read mainlined
dynamic scripts and generate alternate build files for the
designate source. Let me know if I need to expand on this.

You know what, let's cut through the chase. Go ahead an mainline
any infrastructure you think will be sufficient to make it
possible to maintain SystemTap's essential _in the tree_. *Anything*
that you insert in there to make it possible to make *any*
dynamic tracer mainline can and likely will be used to obtain direct
static calls. The only way this doesn't work is if the dynamic
tracer folks have to continue maintaining their stuff out of tree.

See, this not only is Karim evil, but so too are the facts. Even
when manipulated by Ingo, *mechanism* continues to be orthogonal
to *markup*. Now that's evil.
