1122	# SYNOPSIS
1123	#
1124	# DX_INIT_DOXYGEN(PROJECT-NAME, DOXYFILE-PATH, [OUTPUT-DIR])
1125	# DX_DOXYGEN_FEATURE(ON\|OFF)
1126	# DX_DOT_FEATURE(ON\|OFF)

1135	#
1136	# DESCRIPTION
1137	#
1138	# The DX_*_FEATURE macros control the default setting for the given
1139	# Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
1140	# generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
1141	# help (for MS users), 'CHI' for generating a seperate .chi file by the
1142	# .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
1143	# output formats. The environment variable DOXYGEN_PAPER_SIZE may be
1144	# specified to override the default 'a4wide' paper size.
1145	#
1146	# By default, HTML, PDF and PS documentation is generated as this seems to
1147	# be the most popular and portable combination. MAN pages created by
1148	# Doxygen are usually problematic, though by picking an appropriate subset
1149	# and doing some massaging they might be better than nothing. CHM and RTF
1150	# are specific for MS (note that you can't generate both HTML and CHM at
1151	# the same time). The XML is rather useless unless you apply specialized
1152	# post-processing to it.
1153	#
1154	# The macros mainly control the default state of the feature. The use can
1155	# override the default by specifying --enable or --disable. The macros
1156	# ensure that contradictory flags are not given (e.g.,
1157	# --enable-doxygen-html and --enable-doxygen-chm,
1158	# --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
1159	# feature will be automatically disabled (with a warning) if the required
1160	# programs are missing.
1161	#
1162	# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
1163	# with the following parameters: a one-word name for the project for use
1164	# as a filename base etc., an optional configuration file name (the
1165	# default is 'Doxyfile', the same as Doxygen's default), and an optional
1166	# output directory name (the default is 'doxygen-doc').
1167	#
1168	# Automake Support
1169	#
1170	# The following is a template aminclude.am file for use with Automake.
1171	# Make targets and variables values are controlled by the various
1172	# DX_COND_* conditionals set by autoconf.
1173	#
1174	# The provided targets are:
1175	#
1176	# doxygen-doc: Generate all doxygen documentation.
1177	#
1178	# doxygen-run: Run doxygen, which will generate some of the
1179	# documentation (HTML, CHM, CHI, MAN, RTF, XML)
1180	# but will not do the post processing required
1181	# for the rest of it (PS, PDF, and some MAN).
1182	#
1183	# doxygen-man: Rename some doxygen generated man pages.
1184	#
1185	# doxygen-ps: Generate doxygen PostScript documentation.
1186	#
1187	# doxygen-pdf: Generate doxygen PDF documentation.
1188	#
1189	# Note that by default these are not integrated into the automake targets.
1190	# If doxygen is used to generate man pages, you can achieve this
1191	# integration by setting man3_MANS to the list of man pages generated and
1192	# then adding the dependency:
1193	#
1194	# $(man3_MANS): doxygen-doc
1195	#
1196	# This will cause make to run doxygen and generate all the documentation.
1197	#
1198	# The following variable is intended for use in Makefile.am:
1199	#
1200	# DX_CLEANFILES = everything to clean.
1201	#
1202	# Then add this variable to MOSTLYCLEANFILES.

1648	# SYNOPSIS
1649	#
1650	# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
1651	#
1652	# DESCRIPTION
1653	#
1654	# This macro figures out how to build C programs using POSIX threads. It
1655	# sets the PTHREAD_LIBS output variable to the threads library and linker
1656	# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
1657	# flags that are needed. (The user can also force certain compiler
1658	# flags/libs to be tested by setting these environment variables.)
1659	#
1660	# Also sets PTHREAD_CC to any special C compiler that is needed for
1661	# multi-threaded programs (defaults to the value of CC otherwise). (This
1662	# is necessary on AIX to use the special cc_r compiler alias.)
1663	#
1664	# NOTE: You are assumed to not only compile your program with these flags,
1665	# but also link it with them as well. e.g. you should link with
1666	# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
1667	#
1668	# If you are only building threads programs, you may wish to use these
1669	# variables in your default LIBS, CFLAGS, and CC:
1670	#
1671	# LIBS="$PTHREAD_LIBS $LIBS"
1672	# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
1673	# CC="$PTHREAD_CC"
1674	#
1675	# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
1676	# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
1677	# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
1678	#
1679	# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
1680	# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
1681	# PTHREAD_CFLAGS.
1682	#
1683	# ACTION-IF-FOUND is a list of shell commands to run if a threads library
1684	# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
1685	# is not found. If ACTION-IF-FOUND is not specified, the default action
1686	# will define HAVE_PTHREAD.
1687	#
1688	# Please let the authors know if this macro fails on any platform, or if
1689	# you have any other suggestions or comments. This macro was based on work
1690	# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
1691	# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
1692	# Alejandro Forero Cuervo to the autoconf macro repository. We are also
1693	# grateful for the helpful feedback of numerous users.

2154	#
2155	# Of course, Automake must honor this variable whenever it calls a
2156	# tool from the auxiliary directory. The problem is that $srcdir (and
2157	# therefore $ac_aux_dir as well) can be either absolute or relative,
2158	# depending on how configure is run. This is pretty annoying, since
2159	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
2160	# source directory, any form will work fine, but in subdirectories a
2161	# relative path needs to be adjusted first.
2162	#
2163	# $ac_aux_dir/missing
2164	# fails when called from a subdirectory if $ac_aux_dir is relative
2165	# $top_srcdir/$ac_aux_dir/missing
2166	# fails if $ac_aux_dir is absolute,
2167	# fails when called from a subdirectory in a VPATH build with
2168	# a relative $ac_aux_dir
2169	#
2170	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2171	# are both prefixed by $srcdir. In an in-source build this is usually
2172	# harmless because $srcdir is `.', but things will broke when you
2173	# start a VPATH build or use an absolute $srcdir.
2174	#
2175	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
2176	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
2177	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//\(.\)"`
2178	# and then we would define $MISSING as
2179	# MISSING="\${SHELL} $am_aux_dir/missing"

2183	# configure, and could therefore not use this "fixed" $ac_aux_dir.
2184	#
2185	# Another solution, used here, is to always expand $ac_aux_dir to an
