# @options optionspec
#
# Specifies configuration-time options which may be selected by the user
# and checked with 'opt-str' and 'opt-bool'. '$optionspec' contains a series
# of options specifications separated by newlines, as follows:
#
# A boolean option is of the form:
#
## name[=0|1]  => "Description of this boolean option"
#
# The default is 'name=0', meaning that the option is disabled by default.
# If 'name=1' is used to make the option enabled by default, the description should reflect
# that with text like "Disable support for ...".
#
# An argument option (one which takes a parameter) is of the form:
# An argument option (one which takes a parameter) is of one of the following forms:
#
## name:[=]value  => "Description of this option"
## name:value         => "Description of this option"
## name:value=default => "Description of this option with a default value"
## name:=value        => "Description of this option with an optional value"
#
# If the 'name:value' form is used, the value must be provided with the option (as '--name=myvalue').
# If the 'name:value=default' form is used, the option has the given default value even if not
# specified by the user.
# If the 'name:=value' form is used, the value is optional and the given value is used as the default
# If the 'name:=value' form is used, the value is optional and the given value is used
# if it is not provided.
#
# The description may contain '@default@', in which case it will be replaced with the default
# value for the option (taking into account defaults specified with 'options-defaults'.
#
# Undocumented options are also supported by omitting the '=> description'.
# These options are not displayed with '--help' and can be useful for internal options or as aliases.
#
# For example, '--disable-lfs' is an alias for '--disable=largefile':
#
## lfs=1 largefile=1 => "Disable large file support"

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

# You can get the latest version of this script from:
# https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub
# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub

# 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.
# Each package is responsible for reporting which valid configurations
# it does not support.  The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.

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

# The "shellcheck disable" line above the timestamp inhibits complaints
# about features and limitations of the classic Bourne shell that were
# superseded or lifted in POSIX.  However, this script identifies a wide
# variety of pre-POSIX systems that do not have POSIX shells at all, and
# even some reasonably current systems (Solaris 10 as case-in-point) still
# have a pre-POSIX /bin/sh.

 * hash (UUID) of each F card is the same AND we're NOT diffing the checkout on
 * to dump the complete content of the added/deleted file if FSL_DIFF_VERBOSE is
