# $Id: options,v 1.75 1998/05/25 10:37:40 julian Exp $
#
# On the handling of kernel options
#
# All kernel options should be listed in LINT, with suitable
# descriptions. Negative options (options that make some code not
# compile) should be commented out; LINT 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 include
# "opt_lint.h" and check for COMPILING_LINT to get maximum code
# coverage.
#
# All new options shall also be listed in either "conf/options" or
# "<machine>/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 affect
# 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
# Miscellaneous options.
