# Configuration subroutine to validate and canonicalize a configuration type.

# Supply the specified configuration type as an argument.

# that are meaningful with *any* GNU software.

# Each package is responsible for reporting which valid configurations

50 
# a failure to support a valid configuration from a meaningless
51 
# configuration.

# The goal of this file is to map all the various variations of a given
54 
# machine specification into a single specification in the form:

56 
# or in some cases, the newer four-part form:
57 
#       CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
58
