! 18: dnl This file is an m4 file, really. It's a clone of MAKEDEV.sub, then
! 19: dnl adapted to mdoc output. This means, mostly removed from any non-trivial
! 20: dnl content...
! 21: dnl
! 22: dnl o First, a change of quote to make shell statements like: `command`
! 23: dnl possible
! 24: dnl
! 25: changequote(`{-', `-}')dnl
! 26: dnl
! 27: dnl o version info must be stripped of $ so we can say 'generated from' below
! 28: dnl
! 29: dnl If we just use the version string how are we going to know what arch
! 30: dnl 'MAKEDEV.md,v' came from?
! 31: dnl
! 32: dnl Thus, I have used the below to create a version string looking like
! 33: dnl 'OpenBSD: etc.sparc/MAKEDEV.inc,v...' which works, although requires
! 34: dnl some attention if ported to another Id string setup.
