 # work. To ensure they do work, we have to duplicate thee few lines here.

 # $FreeBSD$
 #
 #        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
