+Installation Instructions
+*************************
+
+Basic Installation
+==================
+
+   The following shell commands:
+
+     test -f configure || ./bootstrap
+     ./configure
+     make
+     make install
+
+should configure, build, and install this package.  The ‘./bootstrap’
+line is intended for developers; you can omit it when building from a
+distribution tarball.
+
+   The following more-detailed instructions are generic; see the
+‘README’ file for instructions specific to this package.  Some packages
+provide this ‘INSTALL’ file but do not implement all of the features
+documented below.  The lack of an optional feature in a given package is
+not necessarily a bug.  More recommendations for GNU packages can be
+found in the GNU Coding Standards.
+
+   If the ‘bootstrap’ shell script exists, it attempts to build the
+‘configure’ shell script and related files, perhaps by downloading other
+software components from the network, and by using developer tools that
+are less commonly installed.  Because the output of ‘bootstrap’ is
+system-independent, it is normally run by a package developer so that
+its output can be put into the distribution tarball and ordinary
+builders and users need not run ‘bootstrap’.  Some packages have
+commands like ‘./autopull.sh’ and ‘./autogen.sh’ that you can run
+instead of ‘./bootstrap’, for more fine-grained control over
+bootstrapping.
+
+   The ‘configure’ shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a ‘Makefile’ in each directory of the package.
+It may also create one or more ‘.h’ files containing system-dependent
+definitions.  Finally, it creates a shell script ‘config.status’ that
+you can run in the future to recreate the current configuration, and a
+file ‘config.log’ containing output useful for debugging ‘configure’.
+
+   It can also use an optional file (typically called ‘config.cache’ and
+enabled with ‘--cache-file=config.cache’ or simply ‘-C’) that saves the
+results of its tests to speed up reconfiguring.  Caching is disabled by
+default to prevent problems with accidental use of stale cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how ‘configure’ could check whether to do them, and mail
+diffs or instructions to the address given in the ‘README’ so they can
+be considered for the next release.  If you are using the cache, and at
+some point ‘config.cache’ contains results you don’t want to keep, you
+may remove or edit it.
+
+   The ‘autoconf’ program generates ‘configure’ from the file
+‘configure.ac’.  Normally you should edit ‘configure.ac’ instead of
+editing ‘configure’ directly.
+
+   The simplest way to compile this package is:
+
+  1. ‘cd’ to the directory containing the package’s source code.
+
+  2. If this is a developer checkout and file ‘configure’ does not yet
+     exist, type ‘./bootstrap’ to create it.  You may need special
+     developer tools and network access to bootstrap.
+
+  3. Type ‘./configure’ to configure the package for your system.  This
+     might take a while.  While running, ‘configure’ prints messages
+     telling which features it is checking for.
+
+  4. Type ‘make’ to compile the package.
+
+  5. Optionally, type ‘make check’ to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  6. Type ‘make install’ to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the ‘make install’ phase executed with root
+     privileges.
+
+  7. Optionally, type ‘make installcheck’ to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior ‘make install’ required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  8. You can remove the program binaries and object files from the
+     source code directory by typing ‘make clean’.  To also remove the
+     files that ‘configure’ created (so you can compile the package for
+     a different kind of computer), type ‘make distclean’.  There is
+     also a ‘make maintainer-clean’ target, but that is intended mainly
+     for the package’s developers.  If you use it, you may have to
+     bootstrap again.
+
+  9. If the package follows the GNU Coding Standards, you can type ‘make
+     uninstall’ to remove the installed files.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the ‘configure’ script does not know about.  Run ‘./configure --help’
+for details on some of the pertinent environment variables.
+
+   You can give ‘configure’ initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here is
+an example:
+
+     ./configure CC=gcc CFLAGS=-g LIBS=-lposix
+
+   See *note Defining Variables:: for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each system in their own
+directory.  To do this, you can use GNU ‘make’.  ‘cd’ to the directory
+where you want the object files and executables to go and run the
+‘configure’ script.  ‘configure’ automatically checks for the source
+code in the directory that ‘configure’ is in and in ‘..’.  This is known
+as a “VPATH” build.
+
+   With a non-GNU ‘make’, it is safer to compile the package for one
+system at a time in the source code directory.  After you have installed
+the package for one system, use ‘make distclean’ before reconfiguring
+for another system.
+
+   Some platforms, notably macOS, support “fat” or “universal” binaries,
+where a single binary can execute on different architectures.  On these
+platforms you can configure and compile just once, with options specific
+to that platform.
+
+Installation Names
+==================
+
+   By default, ‘make install’ installs the package’s commands under
+‘/usr/local/bin’, include files under ‘/usr/local/include’, etc.  You
+can specify an installation prefix other than ‘/usr/local’ by giving
+‘configure’ the option ‘--prefix=PREFIX’, where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option ‘--exec-prefix=PREFIX’ to ‘configure’, the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like ‘--bindir=DIR’ to specify different values for particular
+kinds of files.  Run ‘configure --help’ for a list of the directories
+you can set and what kinds of files go in them.  In general, the default
+for these options is expressed in terms of ‘${prefix}’, so that
+specifying just ‘--prefix’ will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to ‘configure’; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+‘make install’ command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, ‘make install
+prefix=/alternate/directory’ will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+‘${prefix}’.  Any directories that were specified during ‘configure’,
+but not in terms of ‘${prefix}’, must each be overridden at install time
+for the entire installation to be relocated.  The approach of makefile
+variable overrides for each directory variable is required by the GNU
+Coding Standards, and ideally causes no recompilation.  However, some
+platforms have known limitations with the semantics of shared libraries
+that end up requiring recompilation when using this method, particularly
+noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the ‘DESTDIR’ variable.  For
+example, ‘make install DESTDIR=/alternate/directory’ will prepend
+‘/alternate/directory’ before all installation names.  The approach of
+‘DESTDIR’ overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of ‘${prefix}’
+at ‘configure’ time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving ‘configure’ the
+option ‘--program-prefix=PREFIX’ or ‘--program-suffix=SUFFIX’.
+
+   Some packages pay attention to ‘--enable-FEATURE’ and
+‘--disable-FEATURE’ options to ‘configure’, where FEATURE indicates an
+optional part of the package.  They may also pay attention to
+‘--with-PACKAGE’ and ‘--without-PACKAGE’ options, where PACKAGE is
+something like ‘gnu-ld’.  ‘./configure --help’ should mention the
+‘--enable-...’ and ‘--with-...’ options that the package recognizes.
+
+   Some packages offer the ability to configure how verbose the
+execution of ‘make’ will be.  For these packages, running ‘./configure
+--enable-silent-rules’ sets the default to minimal output, which can be
+overridden with ‘make V=1’; while running ‘./configure
+--disable-silent-rules’ sets the default to verbose, which can be
+overridden with ‘make V=0’.
+
+Specifying a System Type
+========================
+
+   By default ‘configure’ builds for the current system.  To create
+binaries that can run on a different system type, specify a
+‘--host=TYPE’ option along with compiler variables that specify how to
+generate object code for TYPE.  For example, to create binaries intended
+to run on a 64-bit ARM processor:
+
+     ./configure --host=aarch64-linux-gnu \
+        CC=aarch64-linux-gnu-gcc \
+        CXX=aarch64-linux-gnu-g++
+
+If done on a machine that can execute these binaries (e.g., via
+‘qemu-aarch64’, ‘$QEMU_LD_PREFIX’, and Linux’s ‘binfmt_misc’
+capability), the build behaves like a native build.  Otherwise it is a
+cross-build: ‘configure’ will make cross-compilation guesses instead of
+running test programs, and ‘make check’ will not work.
+
+   A system type can either be a short name like ‘mingw64’, or a
+canonical name like ‘x86_64-pc-linux-gnu’.  Canonical names have the
+form CPU-COMPANY-SYSTEM where SYSTEM is either OS or KERNEL-OS.  To
+canonicalize and validate a system type, you can run the command
+‘config.sub’, which is often squirreled away in a subdirectory like
+‘build-aux’.  For example:
+
+     $ build-aux/config.sub arm64-linux
+     aarch64-unknown-linux-gnu
+     $ build-aux/config.sub riscv-lnx
+     Invalid configuration 'riscv-lnx': OS 'lnx' not recognized
+
+You can look at the ‘config.sub’ file to see which types are recognized.
+If the file is absent, this package does not need the system type.
+
+   If ‘configure’ fails with the diagnostic “cannot guess build type”.
+‘config.sub’ did not recognize your system’s type.  In this case, first
+fetch the newest versions of these files from the GNU config package
+(https://savannah.gnu.org/projects/config).  If that fixes things,
+please report it to the maintainers of the package containing
+‘configure’.  Otherwise, you can try the configure option ‘--build=TYPE’
+where TYPE comes close to your system type; also, please report the
+problem to <config-patches@gnu.org>.
+
+   For more details about configuring system types, see the Autoconf
+documentation.
+
+Sharing Defaults
+================
+
+   If you want to set default values for ‘configure’ scripts to share,
+you can create a site shell script called ‘config.site’ that gives
+default values for variables like ‘CC’, ‘cache_file’, and ‘prefix’.
+‘configure’ looks for ‘PREFIX/share/config.site’ if it exists, then
+‘PREFIX/etc/config.site’ if it exists.  Or, you can set the
+‘CONFIG_SITE’ environment variable to the location of the site script.
+A warning: not all ‘configure’ scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to ‘configure’.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the ‘configure’ command line, using ‘VAR=value’.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified ‘gcc’ to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for ‘CONFIG_SHELL’ due to an
+Autoconf limitation.  Until the limitation is lifted, you can use this
+workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+‘configure’ Invocation
+======================
+
+   ‘configure’ recognizes the following options to control how it
+operates.
+
+‘--help’
+‘-h’
+     Print a summary of all of the options to ‘configure’, and exit.
+
+‘--help=short’
+‘--help=recursive’
+     Print a summary of the options unique to this package’s
+     ‘configure’, and exit.  The ‘short’ variant lists options used only
+     in the top level, while the ‘recursive’ variant lists options also
+     present in any nested packages.
+
+‘--version’
+‘-V’
+     Print the version of Autoconf used to generate the ‘configure’
+     script, and exit.
+
+‘--cache-file=FILE’
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally ‘config.cache’.  FILE defaults to ‘/dev/null’ to
+     disable caching.
+
+‘--config-cache’
+‘-C’
+     Alias for ‘--cache-file=config.cache’.
+
+‘--srcdir=DIR’
+     Look for the package’s source code in directory DIR.  Usually
+     ‘configure’ can determine that directory automatically.
+
+‘--prefix=DIR’
+     Use DIR as the installation prefix.  *note Installation Names:: for
+     more details, including other options available for fine-tuning the
+     installation locations.
+
+‘--host=TYPE’
+     Build binaries for system TYPE.  *Note System Types::.
+
+‘--enable-FEATURE’
+‘--disable-FEATURE’
+     Enable or disable the optional FEATURE.  *Note Optional Features::.
+
+‘--with-PACKAGE’
+‘--without-PACKAGE’
+     Use or omit PACKAGE when building.  *Note Optional Features::.
+
+‘--quiet’
+‘--silent’
+‘-q’
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to ‘/dev/null’ (any error
+     messages will still be shown).
+
+‘--no-create’
+‘-n’
+     Run the configure checks, but stop before creating any output
+     files.
+
+‘configure’ also recognizes several environment variables, and accepts
+some other, less widely useful, options.  Run ‘configure --help’ for
+more details.
