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.
