# $FreeBSD$
#
#        On the handling of kernel options
#
# All kernel options should be listed in NOTES, with suitable
# descriptions.  Negative options (options that make some code not
# compile) should be commented out; LINT (generated from NOTES) should
# compile as much code as possible.  Try to structure option-using
# code so that a single option only switch code on, or only switch
# code off, to make it possible to have a full compile-test.  If
# necessary, you can check for COMPILING_LINT to get maximum code
# coverage.
#
# All new options shall also be listed in either "conf/options" or
# "conf/options.<machine>".  Options that affect a single source-file
# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options
# that affect multiple files should either go in "opt_global.h" if
# this is a kernel-wide option (used just about everywhere), or in
# "opt_<option-name-in-lower-case>.h" if it affects only some files.
# Note that the effect of listing only an option without a
# header-file-name in conf/options (and cousins) is that the last
# convention is followed.
#
# This handling scheme is not yet fully implemented.
#
#
# Format of this file:
# Option name	filename
#
# If filename is missing, the default is
# opt_<name-of-option-in-lower-case>.h
