Next should come device, options, and hints lines in that 2739219Sgibbs# order. All device and option lines must be described by a comment that 2850477Speter# doesn't just expand the device or option name. Use only a concise 2939219Sgibbs# comment on the same line if possible. Very detailed descriptions of 3039219Sgibbs# devices and subsystems belong in man pages. 3139219Sgibbs# 3239219Sgibbs# A space followed by a tab separates 'options' from an option name. Two 3339219Sgibbs# spaces followed by a tab separate 'device' from a device name. Comments 3439219Sgibbs# after an option or device should use one space after the comment character. 3539219Sgibbs# To comment out a negative option that disables code and thus should not be 3639219Sgibbs# enabled for LINT builds, precede 'options' with "#!". 3739219Sgibbs# 3839219Sgibbs 3939219Sgibbs# 4039219Sgibbs# This is the ``identification'' of the kernel.
