1# $FreeBSD$
2#
3#        On the handling of kernel options
4#
5# All kernel options should be listed in NOTES, with suitable
6# descriptions.  Negative options (options that make some code not
7# compile) should be commented out; LINT (generated from NOTES) should
8# compile as much code as possible.  Try to structure option-using
9# code so that a single option only switch code on, or only switch
10# code off, to make it possible to have a full compile-test.  If
11# necessary, you can check for COMPILING_LINT to get maximum code
12# coverage.
13#
14# All new options shall also be listed in either "conf/options" or
15# "conf/options.<machine>".  Options that affect a single source-file
16# <xxx>.[c|s] should be directed into "opt_<xxx>.h", while options
17# that affect multiple files should either go in "opt_global.h" if
18# this is a kernel-wide option (used just about everywhere), or in
19# "opt_<option-name-in-lower-case>.h" if it affects only some files.
20# Note that the effect of listing only an option without a
21# header-file-name in conf/options (and cousins) is that the last
22# convention is followed.
23#
24# This handling scheme is not yet fully implemented.
25#
26#
27# Format of this file:
28# Option name	filename
29#
30# If filename is missing, the default is
31# opt_<name-of-option-in-lower-case>.h
