# Configuration subroutine to validate and canonicalize a configuration type.
38
# Supply the specified configuration type as an argument.
39
# If it is invalid, we print an error message on stderr and exit with code 1.
40
# Otherwise, we print the canonical config type on stdout and succeed.

# This file is supposed to be the same for all GNU packages

# and recognize all the CPU types, system types and aliases

# that are meaningful with *any* GNU software.
45
# Each package is responsible for reporting which valid configurations
46
# it does not support.  The user should be able to distinguish
47
# a failure to support a valid configuration from a meaningless
48
# configuration.

# The goal of this file is to map all the various variations of a given
51
# machine specification into a single specification in the form:
52
#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
53
# or in some cases, the newer four-part form:
54
#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
55
# It is wrong to echo any other type of specification.
