# and recognize all the CPU types, system types and aliases
40
# that are meaningful with *any* GNU software.
41
# Each package is responsible for reporting which valid configurations
42
# it does not support.  The user should be able to distinguish
43
# a failure to support a valid configuration from a meaningless
44
# configuration.

46
# The goal of this file is to map all the various variations of a given
47
# machine specification into a single specification in the form:
48
#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
49
# or in some cases, the newer four-part form:
50
#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
51
# It is wrong to echo any other type of specification.
