	32	# Configuration subroutine to validate and canonicalize a configuration type.
	33	# Supply the specified configuration type as an argument.
	34	# If it is invalid, we print an error message on stderr and exit with code 1.
	35	# Otherwise, we print the canonical config type on stdout and succeed.

	43	# Each package is responsible for reporting which valid configurations
	44	# it does not support. The user should be able to distinguish
	45	# a failure to support a valid configuration from a meaningless
	46	# configuration.

	48	# The goal of this file is to map all the various variations of a given
	49	# machine specification into a single specification in the form:
	50	# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
	51	# or in some cases, the newer four-part form:
	52	# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
	53	# It is wrong to echo any other type of specification.

	58	# variety of pre-POSIX systems that do not have POSIX shells at all, and
	59	# even some reasonably current systems (Solaris 10 as case-in-point) still
	60	# have a pre-POSIX /bin/sh.
