Hello,
I've experimented a little with the DrFred's GNU indent settings,
they were good, however I advanced them more and found out almost
perfect set of settings which suits our proposed/official coding
style (the only debateble part was using TAB vs. SPACEs, but for some
areas like ntoskrnl TAB-based indentind is de-facto not used at all).
For further info / remaining problems, look to the following URL:

Aleksey Bragin.
