NetBSD cauchy.polynum.local 10.0_BETA NetBSD 10.0_BETA (cauchy) #0: Mon Feb 27 11:28:34 CET 2023  tlaronde@cauchy.polynum.local:/usr/obj/polynum.NODECONF-cauchy.polynum.local_netbsd-9.3-amd64_netbsd-amd64/netbsd/obj/sys/arch/amd64/compile/cauchy amd64

Stock userland; native X11; native xterm.

The xterm is launched through twm with this:

"Xterm"		f.exec "LC_CTYPE=fr_FR.ISO8859-15; exec xterm -bg black -fg white -geometry +100+1 -ls&"
