# Configuration subroutine to validate and canonicalize a configuration type.
37
# Supply the specified configuration type as an argument.
38
# If it is invalid, we print an error message on stderr and exit with code 1.
39
# Otherwise, we print the canonical config type on stdout and succeed.

41
# This file is supposed to be the same for all GNU packages
42
# and recognize all the CPU types, system types and aliases
43
# that are meaningful with *any* GNU software.
44
# Each package is responsible for reporting which valid configurations
45
# it does not support.  The user should be able to distinguish
46
# a failure to support a valid configuration from a meaningless
47
# configuration.

# The goal of this file is to map all the various variations of a given
50
# machine specification into a single specification in the form:
51
#       CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
52
# or in some cases, the newer four-part form:
53
#       CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
54
# It is wrong to echo any other type of specification.
