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