+# 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/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+# superseded or lifted in POSIX.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.

+# We use this within the standard %configure macro, but also make it available
+# for packages which don't use %configure
+#
+# The first three are common ways to test for the existence of a function, so
+# we ensure the reference to the function is preserved
+#
+# The fourth are constants used to then try to generate NaNs and other key
+# floating point numbers.  We then use those special FP numbers to try and
+# raise a SIGFPE.  By declaring x & y volatile we prevent the optimizers
+# from removing the computation
+#
+# The fifth (and worst) addresses problems with autoconf/libtool's approach
+# to extracting symbols from .o files and generating C code.  In an LTO world
+# types matter much more closely and you can't have an object in one context
+# that is a function definition and a simple scalar variable in another.
+# Thankfully HP-UX has always had that restriction and is supported by
+# autoconf/libtool.  The insane sed script replaces the "generic" code with
+# the HP-UX version.
+#
+# If we do not make changes, we put the original file back.  This avoids
+# unnecessary rebuilds of things that may have dependencies on the configure
+# files.

+# Map forge information to rpm metadata. This macro will compute default spec
+# variable values.
+#
+# The following spec variables SHOULD be set before calling the macro:
+#
+#   forgeurl  the project url on the forge, strongly recommended;
+#             alternatively, use -u <url>
+#   Version   if applicable, set it with Version: <version>
+#   tag       if applicable
+#   commit    if applicable
+#   date      if applicable (to override the mtime of the Source archive)
+#
+# The macro will attempt to compute and set the following variables if they are
+# not already set by the packager:
+#
+#   forgesource    an URL that can be used as SourceX: value
+#   forgesetupargs the correct arguments to pass to %setup for this source
+#                  used by %forgesetup and %forgeautosetup
+#   archivename    the source archive filename, without extentions
+#   archiveext     the source archive filename extensions, without leading dot
+#   archiveurl     the url that can be used to download the source archive,
+#                  without renaming
+#   scm            the scm type, when packaging code snapshots: commits or tags
+#
+# If the macro is unable to parse your forgeurl value set at least archivename
+# and archiveurl before calling it.
+#
+# Most of the computed variables are both overridable and optional. However,
+# the macro WILL REDEFINE %{dist} when packaging a snapshot (commit or tag).
+# The previous %{dist} value will be lost. Don’t call the macro if you don’t
+# wish %{dist} to be changed.
+#
+# Optional parameters:
+#   -u <url>  Ignore forgeurl even if it exists and use <url> instead. Note
+#             that the macro will still end up setting <url> as the forgeurl
+#             spec variable if it manages to parse it.
+#   -s  Silently ignore problems in forgeurl, use it if it can be parsed,
+#       ignore it otherwise.
+#   -p  Restore problem handling, override -s.
+#   -v  Be verbose and print every spec variable the macro sets.
+#   -i  Print some info about the state of spec variables the macro may use or
+#       set at the end of the processing.

+#   forgesetupargs the correct arguments to pass to %setup for this source
+#                  used by %forgesetup and %forgeautosetup
+#   archivename    the source archive filename, without extentions
+#   archiveext     the source archive filename extensions, without leading dot
+#   archiveurl     the url that can be used to download the source archive,
+#                  without renaming
+#   scm            the scm type, when packaging code snapshots: commits or tags
+#
+# If the macro is unable to parse your forgeurl value set at least archivename
+# and archiveurl before calling it.
+#
+# Most of the computed variables are both overridable and optional. However,
+# the macro WILL REDEFINE %{dist} when packaging a snapshot (commit or tag).
+# The previous %{dist} value will be lost. Don’t call the macro if you don’t
+# wish %{dist} to be changed.
+#
+# Optional parameters:
+#   -u <url>  Ignore forgeurl even if it exists and use <url> instead. Note
+#             that the macro will still end up setting <url> as the forgeurl
+#             spec variable if it manages to parse it.
+#   -s  Silently ignore problems in forgeurl, use it if it can be parsed,
+#       ignore it otherwise.
+#   -p  Restore problem handling, override -s.
+#   -v  Be verbose and print every spec variable the macro sets.

+# If custom files/directories need to be specified, this can be done as such:
