+# On such systems, the usual invocation of an executable through execlp()
+# or execvp() fails with ENOEXEC if it is a script that does not start
+# with a #! line. The script interpreter mentioned in the #! line has
+# to be /bin/sh, because on GuixSD systems that is the only program that
+# has a fixed file name. The second line is essential for perl and is
+# also useful for editing this file in Emacs. The next two lines below
+# are valid code in both sh and perl. When executed by sh, they re-execute
+# the script through the perl program found in $PATH. The '-x' option
+# is essential as well; without it, perl would re-execute the script
+# through /bin/sh. When executed by perl, the next two lines are a no-op.

+# Configuration subroutine to validate and canonicalize a configuration type.

+# 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.

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+# superseded or lifted in POSIX.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

+## dummy dependencies for each header file. Too bad gcc doesn't do

+
+Typical sequence:
+ cd PACKAGESOURCE/doc
+ wget \"$scripturl\"
+ wget \"$templateurl\"
+ $prog --email BUGLIST MANUAL \"GNU MANUAL - One-line description\"
+
+Output will be in a new subdirectory \"manual\" (by default;
+use -o OUTDIR to override). Move all the new files into your web CVS
+tree, as explained in the Web Pages node of maintain.texi.
+
+Please use the --email ADDRESS option so your own bug-reporting
+address will be used in the generated HTML pages.
+
+MANUAL-TITLE is included as part of the HTML <title> of the overall
+manual/index.html file. It should include the name of the package being
+documented. manual/index.html is created by substitution from the file
+$GENDOCS_TEMPLATE_DIR/gendocs_template. (Feel free to modify the
+generic template for your own purposes.)
+
+If you have several manuals, you'll need to run this script several
+times with different MANUAL values, specifying a different output
+directory with -o each time. Then write (by hand) an overall index.html
+with links to them all.
+
+If a manual's Texinfo sources are spread across several directories,
+first copy or symlink all Texinfo sources into a single directory.
+(Part of the script's work is to make a tar.gz of the sources.)
+
+As implied above, by default monolithic Info files are generated.
+If you want split Info, or other Info options, use --info to override.
+
+You can set the environment variables MAKEINFO, TEXI2DVI, TEXI2HTML,
+and PERL to control the programs that get executed, and
+GENDOCS_TEMPLATE_DIR to control where the gendocs_template file is
+looked for. With --docbook, the environment variables DOCBOOK2HTML,
+DOCBOOK2PDF, and DOCBOOK2TXT are also consulted.
+
+By default, makeinfo and texi2dvi are run in the default (English)
+locale, since that's the language of most Texinfo manuals. If you
+happen to have a non-English manual and non-English web site, see the
+SETLANG setting in the source.

+# This script is derived from GIT-VERSION-GEN from GIT: https://git-scm.com/.
+# It may be run two ways:
+# - from a git repository in which the "git describe" command below
+# produces useful output (thus requiring at least one signed tag)
+# - from a non-git-repo directory containing a .tarball-version file, which
+# presumes this script is invoked like "./git-version-gen .tarball-version".
+
+# In order to use intra-version strings in your project, you will need two
+# separate generated version string files:
+#
+# .tarball-version - present only in a distribution tarball, and not in
+# a checked-out repository. Created with contents that were learned at
+# the last time autoconf was run, and used by git-version-gen. Must not
+# be present in either $(srcdir) or $(builddir) for git-version-gen to
+# give accurate answers during normal development with a checked out tree,
+# but must be present in a tarball when there is no version control system.
+# Therefore, it cannot be used in any dependencies. GNUmakefile has
+# hooks to force a reconfigure at distribution time to get the value
+# correct, without penalizing normal development with extra reconfigures.
+#
+# .version - present in a checked-out repository and in a distribution
+# tarball. Usable in dependencies, particularly for files that don't
+# want to depend on config.h but do want to track version changes.
+# Delete this file prior to any autoconf run where you want to rebuild
+# files to pick up a version string change; and leave it stale to
+# minimize rebuild time after unrelated changes to configure sources.
+#
+# As with any generated file in a VC'd directory, you should add
+# /.version to .gitignore, so that you don't accidentally commit it.
+# .tarball-version is never generated in a VC'd directory, so needn't
+# be listed there.
+#
+# Use the following line in your configure.ac, so that $(VERSION) will
+# automatically be up-to-date each time configure is run (and note that
+# since configure.ac no longer includes a version string, Makefile rules
+# should not depend on configure.ac for version updates).
+#
+# AC_INIT([GNU project],
+# m4_esyscmd([build-aux/git-version-gen .tarball-version]),
+# [bug-project@example])
+#
+# Then use the following lines in your Makefile.am, so that .version

+# on systems that are compliant to a POSIX version before POSIX:2017.
+# On such systems, the usual invocation of an executable through execlp()
+# or execvp() fails with ENOEXEC if it is a script that does not start
+# with a #! line. The script interpreter mentioned in the #! line has
+# to be /bin/sh, because on GuixSD systems that is the only program that
+# has a fixed file name. The second line is essential for perl and is
+# also useful for editing this file in Emacs. The next two lines below
+# are valid code in both sh and perl. When executed by sh, they re-execute
+# the script through the perl program found in $PATH. The '-x' option
+# is essential as well; without it, perl would re-execute the script
+# through /bin/sh. When executed by perl, the next two lines are a no-op.

+Usage: $ME [OPTIONS] [ARGS]
+
+Convert git log output to ChangeLog format. If present, any ARGS
+are passed to "git log". To avoid ARGS being parsed as options to
+$ME, they may be preceded by '--'.
+
+OPTIONS:
+
+ --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+ makes a change to SHA1's commit log text or metadata.
+ --append-dot append a dot to the first line of each commit message if
+ there is no other punctuation or blank at the end.
+ --no-cluster never cluster commit messages under the same date/author
+ header; the default is to cluster adjacent commit messages
+ if their headers are the same and neither commit message
+ contains multiple paragraphs.
+ --srcdir=DIR the root of the source tree, from which the .git/
+ directory can be derived.
+ --since=DATE convert only the logs since DATE;
+ the default is to convert all log entries.
+ --until=DATE convert only the logs older than DATE.
+ --ignore-matching=PAT ignore commit messages whose first lines match PAT.
+ --ignore-line=PAT ignore lines of commit messages that match PAT.
+ --format=FMT set format string for commit subject and body;
+ see 'man git-log' for the list of format metacharacters;
+ the default is '%s%n%b%n'
+ --strip-tab remove one additional leading TAB from commit message lines.
+ --strip-cherry-pick remove data inserted by "git cherry-pick";
+ this includes the "cherry picked from commit ..." line,
+ and the possible final "Conflicts:" paragraph.
+ --help display this help and exit
+ --version output version information and exit
+
+EXAMPLE:
+
+ $ME --since=2008-01-01 > ChangeLog
+ $ME -- -n 5 foo > last-5-commits-to-branch-foo
+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line. They are not copied to the output.
+
+ Copyright-paperwork-exempt: Yes
+ Append the "(tiny change)" notation to the usual "date name email"
+ ChangeLog header to mark a change that does not require a copyright
+ assignment.
+ Co-authored-by: Joe User <user\@example.com>
+ List the specified name and email address on a second
+ ChangeLog header, denoting a co-author.
+ Signed-off-by: Joe User <user\@example.com>
+ These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code. Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:
+
+3a169f4c5d9159283548178668d2fae6fced3030
+# fix typo in title:
+s/all tile types/all file types/
+
+1379ed974f1fa39b12e2ffab18b3f7a607082202
+# Due to a bug in vc-dwim, I mis-attributed a patch by Paul to myself.
+# Change the author to be Paul. Note the escaped "@":
+s,Jim .*>,Paul Eggert <eggert\\\@cs.ucla.edu>,

+usage="Usage: $0 [OPTION]... [CMD] FILE... [[CMD] FILE...]
+
+Sign all FILES, and process them at the destinations specified with --to.
+If CMD is not given, it defaults to uploading. See examples below.
+
+Commands:
+ --delete delete FILES from destination
+ --symlink create symbolic links
+ --rmsymlink remove symbolic links
+ -- treat the remaining arguments as files to upload
+
+Options:
+ --to DEST specify a destination DEST for FILES
+ (multiple --to options are allowed)
+ --user NAME sign with key NAME
+ --replace allow replacements of existing files
+ --symlink-regex[=EXPR] use sed script EXPR to compute symbolic link names
+ -n, --dry-run do nothing, show what would have been done
+ (including the constructed directive file)
+ --version output version information and exit
+ -h, --help print this help text and exit
+
+If --symlink-regex is given without EXPR, then the link target name
+is created by replacing the version information with '-latest', e.g.:
+ foo-1.3.4.tar.gz -> foo-latest.tar.gz
+
+Recognized destinations are:
+ alpha.gnu.org:DIRECTORY
+ savannah.gnu.org:DIRECTORY
+ savannah.nongnu.org:DIRECTORY
+ ftp.gnu.org:DIRECTORY
+ build directive files and upload files by FTP
+ download.gnu.org.ua:{alpha|ftp}/DIRECTORY
+ build directive files and upload files by SFTP
+ [user@]host:DIRECTORY upload files with scp
+
+Options and commands are applied in order. If the file $conffile exists
+in the current working directory, its contents are prepended to the
+actual command line options. Use this to keep your defaults. Comments
+(#) and empty lines in $conffile are allowed.
+
+<https://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>
+gives some further background.
+
+Examples:
+1. Upload foobar-1.0.tar.gz to ftp.gnu.org:
+ gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz
+
+2. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
+ gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+3. Same as above, and also create symbolic links to foobar-latest.tar.*:
+ gnupload --to ftp.gnu.org:foobar \\
+ --symlink-regex \\
+ foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+4. Create a symbolic link foobar-latest.tar.gz -> foobar-1.0.tar.gz
+ and likewise for the corresponding .sig file:
+ gnupload --to ftp.gnu.org:foobar \\
+ --symlink foobar-1.0.tar.gz foobar-latest.tar.gz \\
+ foobar-1.0.tar.gz.sig foobar-latest.tar.gz.sig
+ or (equivalent):
+ gnupload --to ftp.gnu.org:foobar \\
+ --symlink foobar-1.0.tar.gz foobar-latest.tar.gz \\
+ --symlink foobar-1.0.tar.gz.sig foobar-latest.tar.gz.sig
+
+5. Upload foobar-0.9.90.tar.gz to two sites:
+ gnupload --to alpha.gnu.org:foobar \\
+ --to sources.redhat.com:~ftp/pub/foobar \\
+ foobar-0.9.90.tar.gz
+
+6. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
+ (the -- terminates the list of files to delete):
+ gnupload --to alpha.gnu.org:foobar \\
+ --to sources.redhat.com:~ftp/pub/foobar \\
+ --delete oopsbar-0.9.91.tar.gz \\
+ -- foobar-0.9.91.tar.gz
+
+gnupload executes a program ncftpput to do the transfers; if you don't
+happen to have an ncftp package installed, the ncftpput-ftp script in
+the build-aux/ directory of the gnulib package
+(https://savannah.gnu.org/projects/gnulib) may serve as a replacement.

+# func_quote_arg MODEs ARG
+# ------------------------
+# Quote one ARG to be evaled later. MODEs argument may contain zero or more
+# specifiers listed below separated by ',' character. This function returns two
+# values:
+# i) func_quote_arg_result
+# double-quoted (when needed), suitable for a subsequent eval
+# ii) func_quote_arg_unquoted_result
+# has all characters that are still active within double
+# quotes backslashified. Available only if 'unquoted' is specified.
+#
+# Available modes:
+# ----------------
+# 'eval' (default)
+# - escape shell special characters
+# 'expand'
+# - the same as 'eval'; but do not quote variable references
+# 'pretty'
+# - request aesthetic output, i.e. '"a b"' instead of 'a\ b'. This might
+# be used later in func_quote to get output like: 'echo "a b"' instead
+# of 'echo a\ b'. This is slower than default on some shells.
+# 'unquoted'
+# - produce also $func_quote_arg_unquoted_result which does not contain
+# wrapping double-quotes.
+#
+# Examples for 'func_quote_arg pretty,unquoted string':
+#
+# string | *_result | *_unquoted_result
+# ------------+-----------------------+-------------------
+# " | \" | \"
+# a b | "a b" | a b

+
+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+# #!/bin/sh
+# . relative/path/to/funclib.sh
+# . relative/path/to/options-parser
+# scriptversion=1.0
+# func_options ${1+"$@"}
+# eval set dummy "$func_options_result"; shift
+# ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# Copyright'.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug in processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath [OPTION]...'
+
+# Short help message in response to '-h' and '--help'. Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.
+usage_message="\
+ --debug enable verbose shell tracing
+ -W, --warnings=CATEGORY
+ report the warnings falling in CATEGORY [all]
+ -v, --verbose verbosely report processing
+ --version print version information and exit
+ -h, --help print short or long help message and exit
+"
+
+# Additional text appended to 'usage_message' in response to '--help'.
+long_help_message="
+Warning categories include:
+ 'all' show all warnings
+ 'none' turn off all the warnings
+ 'error' warnings are treated as fatal errors"

+% Please try the latest version of texinfo.tex before submitting bug

+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution. For a simple
+% manual foo.texi, however, you can get away with this:
+% tex foo.texi
+% texindex foo.??
+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent. You can get the existing language-specific files from the

+# Written by Jim Meyering and Joel E. Denny
+
+# This script updates an FSF copyright year list to include the current year.
+# Usage: update-copyright [FILE...]
+#
+# The arguments to this script should be names of files that contain
+# copyright statements to be updated. The copyright holder's name
+# defaults to "Free Software Foundation, Inc." but may be changed to
+# any other name by using the "UPDATE_COPYRIGHT_HOLDER" environment
+# variable.
+#
+# For example, you might wish to use the update-copyright target rule
+# in maint.mk from gnulib's maintainer-makefile module.
+#
+# Iff a copyright statement is recognized in a file and the final
+# year is not the current year, then the statement is updated for the
+# new year and it is reformatted to:
+#
+# 1. Fit within 72 columns.
+# 2. Convert 2-digit years to 4-digit years by prepending "19".
+# 3. Expand copyright year intervals. (See "Environment variables"
+# below.)
+#
+# A warning is printed for every file for which no copyright
+# statement is recognized.
+#
+# Each file's copyright statement must be formatted correctly in
+# order to be recognized. For example, each of these is fine:
+#
+# Copyright @copyright{} 1990-2005, 2007-2009 Free Software
+# Foundation, Inc.
+#
+# # Copyright (C) 1990-2005, 2007-2009 Free Software
+# # Foundation, Inc.
+#
+# /*
+# * Copyright &copy; 90,2005,2007-2009
+# * Free Software Foundation, Inc.
+# */
+#
+# However, the following format is not recognized because the line
+# prefix changes after the first line:
+#
+# ## Copyright (C) 1990-2005, 2007-2009 Free Software
+# # Foundation, Inc.
+#
+# However, any correctly formatted copyright statement following
+# a non-matching copyright statements would be recognized.
+#
+# The exact conditions that a file's copyright statement must meet
+# to be recognized are:
+#
+# 1. It is the first copyright statement that meets all of the
+# following conditions. Subsequent copyright statements are
+# ignored.
+# 2. Its format is "Copyright (C)", then a list of copyright years,
+# and then the name of the copyright holder.
+# 3. The "(C)" takes one of the following forms or is omitted
+# entirely:
+#
+# A. (C)
+# B. (c)
+# C. @copyright{}
+# D. &copy;
+# E. ©
+#
+# 4. The "Copyright" appears at the beginning of a line, except that it
+# may be prefixed by any sequence (e.g., a comment) of no more than
+# 5 characters -- including white space.
+# 5. Iff such a prefix is present, the same prefix appears at the
+# beginning of each remaining line within the FSF copyright
+# statement. There is one exception in order to support C-style
+# comments: if the first line's prefix contains nothing but
+# whitespace surrounding a "/*", then the prefix for all subsequent
+# lines is the same as the first line's prefix except with each of
+# "/" and possibly "*" replaced by a " ". The replacement of "*"
+# by " " is consistent throughout all subsequent lines.
+# 6. Blank lines, even if preceded by the prefix, do not appear
+# within the FSF copyright statement.
+# 7. Each copyright year is 2 or 4 digits, and years are separated by
+# commas, "-", or "--". Whitespace may appear after commas.
+#
+# Environment variables:
+#
+# 1. If UPDATE_COPYRIGHT_FORCE=1, a recognized FSF copyright statement
+# is reformatted even if it does not need updating for the new
+# year. If unset or set to 0, only updated FSF copyright
+# statements are reformatted.
+# 2. If UPDATE_COPYRIGHT_USE_INTERVALS=1, every series of consecutive
+# copyright years (such as 90, 1991, 1992-2007, 2008) in a
+# reformatted FSF copyright statement is collapsed to a single
+# interval (such as 1990-2008). If unset or set to 0, all existing
+# copyright year intervals in a reformatted FSF copyright statement
+# are expanded instead.
+# If UPDATE_COPYRIGHT_USE_INTERVALS=2, convert a sequence with gaps
+# to the minimal containing range. For example, convert
+# 2000, 2004-2007, 2009 to 2000-2009.
+# 3. For testing purposes, you can set the assumed current year in
+# UPDATE_COPYRIGHT_YEAR.
+# 4. The default maximum line length for a copyright line is 72.
+# Set UPDATE_COPYRIGHT_MAX_LINE_LENGTH to use a different length.
+# 5. Set UPDATE_COPYRIGHT_HOLDER if the copyright holder is other
+# than "Free Software Foundation, Inc.".
