+#
+# To use in your project, import this file in your git repo's toplevel,
+# then do "make -f git.mk".  This modifies all Makefile.am files in
+# your project to -include git.mk.  Remember to add that line to new
+# Makefile.am files you create in your project, or just rerun the
+# "make -f git.mk".
+#
+# This enables automatic .gitignore generation.  If you need to ignore
+# more files, add them to the GITIGNOREFILES variable in your Makefile.am.
+# But think twice before doing that.  If a file has to be in .gitignore,
+# chances are very high that it's a generated file and should be in one
+# of MOSTLYCLEANFILES, CLEANFILES, DISTCLEANFILES, or MAINTAINERCLEANFILES.
+#
+# The only case that you need to manually add a file to GITIGNOREFILES is
+# when remove files in one of mostlyclean-local, clean-local, distclean-local,
+# or maintainer-clean-local make targets.
+#
+# Note that for files like editor backup, etc, there are better places to
+# ignore them.  See "man gitignore".
+#
+# If "make maintainer-clean" removes the files but they are not recognized
+# by this script (that is, if "git status" shows untracked files still), send
+# me the output of "git status" as well as your Makefile.am and Makefile for
+# the directories involved and I'll diagnose.
+#
+# For a list of toplevel files that should be in MAINTAINERCLEANFILES, see
+# Makefile.am.sample in the git.mk git repo.
+#
+# Don't EXTRA_DIST this file.  It is supposed to only live in git clones,
+# not tarballs.  It serves no useful purpose in tarballs and clutters the
+# build dir.
+#
+# This file knows how to handle autoconf, automake, libtool, gtk-doc,
+# gnome-doc-utils, yelp.m4, mallard, intltool, gsettings, dejagnu, appdata,
+# appstream, hotdoc.
+#
+# This makefile provides the following targets:
+#
+# - all: "make all" will build all gitignore files.
+# - gitignore: makes all gitignore files in the current dir and subdirs.
+# - .gitignore: make gitignore file for the current dir.
+# - gitignore-recurse: makes all gitignore files in the subdirs.
+#
+# KNOWN ISSUES:
+#
+# - Recursive configure doesn't work as $(top_srcdir)/git.mk inside the
+#   submodule doesn't find us.  If you have configure.{in,ac} files in
+#   subdirs, add a proxy git.mk file in those dirs that simply does:
+#   "include $(top_srcdir)/../git.mk".  Add more ..'s to your taste.
+#   And add those files to git.  See vte/gnome-pty-helper/git.mk for
+#   example.

+# SYNOPSIS
+#
+#   AX_CHECK_LINK_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   Check whether the given FLAG works with the linker 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 linker's default flags
+#   when the check is done.  The check is thus made with the flags: "LDFLAGS
+#   EXTRA-FLAGS FLAG".  This can for example be used to force the linker to
+#   issue an error when a bad flag is given.
+#
+#   INPUT gives an alternative input source to AC_LINK_IFELSE.
+#
+#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
+#   macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG.

+#
+# SYNOPSIS
+#
+#   AX_CODE_COVERAGE()
+#
+# DESCRIPTION
+#
+#   Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
+#   CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LIBS which should be included
+#   in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LIBADD 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 optimization 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_LIBS) ...
+#     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
+#   has been configured with --enable-code-coverage). Running `make
+#   check-code-coverage` in that directory will run the module's test suite
+#   (`make check`) and build a code coverage report detailing the code which
+#   was touched, then print the URI for the report.
+#
+#   In earlier versions of this macro, CODE_COVERAGE_LDFLAGS was defined
+#   instead of CODE_COVERAGE_LIBS. They are both still defined, but use of
+#   CODE_COVERAGE_LIBS is preferred for clarity; CODE_COVERAGE_LDFLAGS is
+#   deprecated. They have the same value.
+#
+#   This code was derived from Makefile.decl in GLib, originally licenced
+#   under LGPLv2.1+.

+#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the specified
+#   version of the C++ standard.  If necessary, add switches to CXX and
+#   CXXCPP to enable support.  VERSION may be '11' (for the C++11 standard)
+#   or '14' (for the C++14 standard).
+#
+#   The second argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for an extended mode.
+#
+#   The third argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline support for the specified C++ standard is
+#   required and that the macro should error out if no mode with that
+#   support is found.  If specified 'optional', then configuration proceeds
+#   regardless, after defining HAVE_CXX${VERSION} if and only if a
+#   supporting mode is found.

+# 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.
