# Original version were part of Gerd Knorr's v4l scripts.

# Several improvements by (c) 2005-2007 Mauro Carvalho Chehab
#
# Largely re-written (C) 2007 Trent Piepho <xyzzy@speakeasy.org>
# Stolen for DRM usage by airlied
#
# Theory of Operation
#
# This acts as a sort of mini version of cpp, which will process
# #if/#elif/#ifdef/etc directives to strip out code used to support
# multiple kernel versions or otherwise not wanted to be sent upstream to
# git.
#
# Conditional compilation directives fall into two catagories,
# "processed" and "other". The "other" directives are ignored and simply
# output as they come in without changes (see 'keep' exception). The
# "processed" variaty are evaluated and only the lines in the 'true' part
# are kept, like cpp would do.
#
# If gentree knows the result of an expression, that directive will be
# "processed", otherwise it will be an "other". gentree knows the value
# of LINUX_VERSION_CODE, BTTV_VERSION_CODE, the KERNEL_VERSION(x,y,z)
# macro, numeric constants like 0 and 1, and a few defines like MM_KERNEL
# and STV0297_CS2.
#
# An exception is if the comment "/*KEEP*/" appears after the expression,
# in which case that directive will be considered an "other" and not
# processed, other than to remove the keep comment.
#
# Known bugs:
# don't specify the root directory e.g. '/' or even '////'
# directives continued with a back-slash will always be ignored
# you can't modify a source tree in-place, i.e. source dir == dest dir
