	Take a look at the script /bin/machine on the DS3100 (PMAX).  It echos
	the machine type as `mips'.  Hopefully the next release of ULTRIX on
	the VAX will have such a script also but will echo `vax'.  For now though

		# Assume "vax" by default
		set Machine = "vax"
		if( -x /bin/machine ) set Machine = `/bin/machine`

	Not exactly a "/etc/what_kind_of_system_this_is", but does allow you to cleanly
	ifdef things like your .login and .cshrc.
