Maybe i were not enough exact, but i`ve meant
addition of some intelligence to tweaking /proc
e.g. something what automates tuning, not only
providing interface to such actions.
But after lookthru ptweaks source i realized
what its ONLY interface (to proc), and MAYBE
it does some PCI tuning (really intelligent
choices to advance system`s performance).
BTW powertweak is a port from unfamous MD,
therefore when it was created NO proc tuning
was in mind...

There is another argument, telling what doing autotune is ugly by design.... but thats another issue.

Sorry for poor english/lameness
