#
# Based on the IBM machine model, returns a (hopefully) human understandable
# string that identifies the processor.
#
# Usage:
#	cputype
#
# Return values:
# 	1	The script was executed on a system that is a non-IBM mainframe
#		architecture
#	2	The search for the machine type in /proc/cpuinfo returned a null string
#	3	The parsing of the machine type returned a null string
#	4	The machine type found is (probably) a new one, and the script needs to
#		be updated to handle it.
