-	# Installation
-	$(MAKE) DESTDIR=$(CURDIR)/debian/i3-wm/ install

+#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
+#
+# DESCRIPTION
+#
+#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
+#   added in between.
+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
+#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
+#   FLAG.
+#
+#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

+#
+# DESCRIPTION
+#
+#   Try to find a compiler option that enables most reasonable warnings.
+#
+#   For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
+#   is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
+#
+#   Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
+#   HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
+#   Intel compilers.  For a given compiler, the Fortran flags are much more
+#   experimental than their C equivalents.
+#
+#    - $1 shell-variable-to-add-to : CFLAGS, CXXFLAGS, or FCFLAGS
+#    - $2 add-value-if-not-found : nothing
+#    - $3 action-if-found : add value to shellvariable
+#    - $4 action-if-not-found : nothing
+#
+#   NOTE: These macros depend on AX_APPEND_FLAG.

+# SYNOPSIS
+#
+#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   Check whether the given FLAG works with the current language's compiler
+#   or gives an error.  (Warnings, however, are ignored)
+#
+#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
+#   success/failure.
+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
+#
+#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
+#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

+# SYNOPSIS
+#
+#   AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
+#
+# DESCRIPTION
+#
+#   Check for the presence of an --enable-debug option to configure, with
+#   the specified default value used when the option is not present.  Return
+#   the value in the variable $ax_enable_debug.
+#
+#   Specifying 'yes' adds '-g -O0' to the compilation flags for all
+#   languages. Specifying 'info' adds '-g' to the compilation flags.
+#   Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
+#   the linking flags. Otherwise, nothing is added.
+#
+#   Define the variables listed in the second argument if debug is enabled,
+#   defaulting to no variables.  Defines the variables listed in the third
+#   argument if debug is disabled, defaulting to NDEBUG.  All lists of
+#   variables should be space-separated.
+#
+#   If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
+#   Should be invoked prior to any AC_PROG_* compiler checks.
+#
+#   IS-RELEASE can be used to change the default to 'no' when making a
+#   release.  Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
+#   uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
+#   macro, there is no need to pass this parameter.

+# SYNOPSIS
+#
+#   AX_CHECK_GNU_MAKE()
+#
+# DESCRIPTION
+#
+#   This macro searches for a GNU version of make. If a match is found:
+#
+#     * The makefile variable `ifGNUmake' is set to the empty string, otherwise
+#       it is set to "#". This is useful for including a special features in a
+#       Makefile, which cannot be handled by other versions of make.
+#     * The variable `_cv_gnu_make_command` is set to the command to invoke
+#       GNU make if it exists, the empty string otherwise.
+#     * The variable `ax_cv_gnu_make_command` is set to the command to invoke
+#       GNU make by copying `_cv_gnu_make_command`, otherwise it is unset.
+#     * If GNU Make is found, its version is extracted from the output of
+#       `make --version` as the last field of a record of space-separated
+#       columns and saved into the variable `ax_check_gnu_make_version`.
+#
+#   Here is an example of its use:
+#
+#   Makefile.in might contain:
+#
+#     # A failsafe way of putting a dependency rule into a makefile
+#     $(DEPEND):
+#             $(CC) -MM $(srcdir)/*.c > $(DEPEND)
+#
+#     @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
+#     @ifGNUmake@ include $(DEPEND)
+#     @ifGNUmake@ endif
+#
+#   Then configure.in would normally contain:
+#
+#     AX_CHECK_GNU_MAKE()
+#     AC_OUTPUT(Makefile)
+#
+#   Then perhaps to cause gnu make to override any other make, we could do
+#   something like this (note that GNU make always looks for GNUmakefile
+#   first):
+#
+#     if  ! test x$_cv_gnu_make_command = x ; then
+#             mv Makefile GNUmakefile
+#             echo .DEFAULT: > Makefile ;
+#             echo \  $_cv_gnu_make_command \$@ >> Makefile;
+#     fi
+#
+#   Then, if any (well almost any) other make is called, and GNU make also
+#   exists, then the other make wraps the GNU make.

+# SYNOPSIS
+#
+#   AX_CODE_COVERAGE()
+#
+# DESCRIPTION
+#
+#   Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
+#   CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LDFLAGS which should be
+#   included in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LDFLAGS variables of
+#   every build target (program or library) which should be built with code
+#   coverage support. Also defines CODE_COVERAGE_RULES which should be
+#   substituted in your Makefile; and $enable_code_coverage which can be
+#   used in subsequent configure output. CODE_COVERAGE_ENABLED is defined
+#   and substituted, and corresponds to the value of the
+#   --enable-code-coverage option, which defaults to being disabled.
+#
+#   Test also for gcov program and create GCOV variable that could be
+#   substituted.
+#
+#   Note that all optimisation flags in CFLAGS must be disabled when code
+#   coverage is enabled.
+#
+#   Usage example:
+#
+#   configure.ac:
+#
+#     AX_CODE_COVERAGE
+#
+#   Makefile.am:
+#
+#     @CODE_COVERAGE_RULES@
+#     my_program_LIBS = ... $(CODE_COVERAGE_LDFLAGS) ...
+#     my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
+#     my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
+#     my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
+#
+#   This results in a "check-code-coverage" rule being added to any
+#   Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module

+# SYNOPSIS
+#
+#   AX_CONFIGURE_ARGS
+#
+# DESCRIPTION
+#
+#   Helper macro for AX_ENABLE_BUILDDIR.
+#
+#   The traditional way of starting a subdir-configure is running the script
+#   with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
+#   to rely on eval'ing $ac_configure_args however some old autoconf
+#   versions do not provide that. To ensure maximum portability of autoconf
+#   extension macros this helper can be AC_REQUIRE'd so that
+#   $ac_configure_args will alsways be present.
+#
+#   Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
+#   spoiled now and must be replaced by "eval + exit $?".
+#
+#   Example:
+#
+#     AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
+#       AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
+#       eval $SHELL $ac_configure_args || exit $?

+# SYNOPSIS
+#
+#   AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
+#
+# DESCRIPTION
+#
+#   If the current configure was run within the srcdir then we move all
+#   configure-files into a subdir and let the configure steps continue
+#   there. We provide an option --disable-builddir to suppress the move into
+#   a separate builddir.
+#
+#   Defaults:
+#
+#     $1 = $host (overridden with $HOST)
+#     $2 = Makefile.mk
+#     $3 = -all
+#
+#   This macro must be called before AM_INIT_AUTOMAKE. It creates a default
+#   toplevel srcdir Makefile from the information found in the created
+#   toplevel builddir Makefile. It just copies the variables and
+#   rule-targets, each extended with a default rule-execution that recurses
+#   into the build directory of the current "HOST". You can override the
+#   auto-dection through `config.guess` and build-time of course, as in
+#
+#     make HOST=i386-mingw-cross
+#
+#   which can of course set at configure time as well using
+#
+#     configure --host=i386-mingw-cross
+#
+#   After the default has been created, additional rules can be appended
+#   that will not just recurse into the subdirectories and only ever exist
+#   in the srcdir toplevel makefile - these parts are read from the $2 =
+#   Makefile.mk file
+#
+#   The automatic rules are usually scanning the toplevel Makefile for lines
+#   like '#### $host |$builddir' to recognize the place where to recurse
+#   into. Usually, the last one is the only one used. However, almost all
+#   targets have an additional "*-all" rule which makes the script to
+#   recurse into _all_ variants of the current HOST (!!) setting. The "-all"
+#   suffix can be overriden for the macro as well.
+#
+#   a special rule is only given for things like "dist" that will copy the
+#   tarball from the builddir to the sourcedir (or $(PUB)) for reason of
+#   convenience.

+# SYNOPSIS
+#
+#   AX_EXTEND_SRCDIR
+#
+# DESCRIPTION
+#
+#   The AX_EXTEND_SRCDIR macro extends $srcdir by one path component.
+#
+#   As an example, when working in /home/michael/i3-4.12/build and calling
+#   ../configure, your $srcdir is "..". After calling AX_EXTEND_SRCDIR,
+#   $srcdir will be set to "../../i3-4.12".
+#
+#   The result of extending $srcdir is that filenames (e.g. in the output of
+#   the "backtrace" gdb command) will include one more path component of the
+#   absolute source path. The additional path component makes it easy for
+#   users to recognize which files belong to the PACKAGE, and -- provided a
+#   dist tarball was unpacked -- which version of PACKAGE was used.
+#
+#   As an example, in "backtrace", you will see:
+#
+#     #0  main (argc=1, argv=0x7fffffff1fc8) at ../../i3-4.12/src/main.c:187
+#
+#   instead of:
+#
+#     #0  main (argc=1, argv=0x7fffffff1fc8) at ../src/main.c:187
+#
+#   In case your code uses the __FILE__ preprocessor directive to refer to
+#   the filename of the current source file (e.g. in debug messages), using
+#   the extended path might be undesirable. For this purpose,
+#   AX_EXTEND_SRCDIR defines the output variable AX_EXTEND_SRCDIR_CPPFLAGS,
+#   which can be added to AM_CPPFLAGS in Makefile.am in order to define the
+#   preprocessor directive STRIPPED__FILE__. As an example, when compiling
+#   the file "../../i3-4.12/src/main.c", STRIPPED__FILE__ evaluates to
+#   "main.c".
+#
+#   There are some caveats: When $srcdir is "." (i.e. when ./configure was
+#   called instead of ../configure in a separate build directory),
+#   AX_EXTEND_SRCDIR will still extend $srcdir, but the intended effect will
+#   not be achieved because of the way automake specifies file paths:
+#   automake defines COMPILE to use "`test -f '$source' || echo
+#   '\$(srcdir)/'`$source" in order to prefer files in the current directory
+#   over specifying $srcdir explicitly.
+#
+#   The AX_EXTEND_SRCDIR author is not aware of any way to influence this
+#   automake behavior. Patches very welcome.
+#
+#   To work around this issue, you can use AX_ENABLE_BUILDDIR i.e. by adding
+#   the following code to configure.ac:
+#
+#     AX_ENABLE_BUILDDIR
+#     dnl ...
+#     AX_EXTEND_SRCDIR
+#
+#   Then also add this bit to Makefile.am (if you wish to use
+#   STRIPPED__FILE__ in your code):
+#

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+# SYNOPSIS
+#
+#   AX_SANITIZERS([SANITIZERS], [ENABLED-BY-DEFAULT], [ACTION-SUCCESS])
+#
+# DESCRIPTION
+#
+#   Offers users to enable one or more sanitizers (see
+#   https://github.com/google/sanitizers) with the corresponding
+#   --enable-<sanitizer>-sanitizer option.
+#
+#   SANITIZERS is a whitespace-separated list of sanitizers to offer via
+#   --enable-<sanitizer>-sanitizer options, e.g. "address memory" for the
+#   address sanitizer and the memory sanitizer. If SANITIZERS is not specified,
+#   all known sanitizers to AX_SANITIZERS will be offered, which at the time of
+#   writing are "address memory undefined".
+#   NOTE that SANITIZERS is expanded at autoconf time, not at configure time,
+#   i.e. you cannot use shell variables in SANITIZERS.
+#
+#   ENABLED-BY-DEFAULT is a whitespace-separated list of sanitizers which
+#   should be enabled by default, e.g. "memory undefined". Note that not all
+#   sanitizers can be combined, e.g. memory sanitizer cannot be enabled when
+#   address sanitizer is already enabled.
+#   Set ENABLED-BY-DEFAULT to a single whitespace in order to disable all
+#   sanitizers by default.
+#   ENABLED-BY-DEFAULT is expanded at configure time, so you can use shell
+#   variables.
+#
+#   ACTION-SUCCESS allows to specify shell commands to execute on success, i.e.
+#   when one of the sanitizers was successfully enabled. This is a good place
+#   to call AC_DEFINE for any precompiler constants you might need to make your
+#   code play nice with sanitizers.
+#
+#   The variable ax_enabled_sanitizers contains a whitespace-separated list of
+#   all enabled sanitizers, so that you can print them at the end of configure,
+#   if you wish.
+#
+#   The additional --enable-sanitizers option allows users to enable/disable
+#   all sanitizers, effectively overriding ENABLED-BY-DEFAULT.
+#
