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