           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.

           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

           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.

           56 # about features and limitations of the classic Bourne shell that were
           57 # superseded or lifted in POSIX.  However, this script identifies a wide
           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
