1123	# SYNOPSIS
1124	#
1125	# DX_INIT_DOXYGEN(PROJECT-NAME, DOXYFILE-PATH, [OUTPUT-DIR])
1126	# DX_DOXYGEN_FEATURE(ON\|OFF)
1127	# DX_DOT_FEATURE(ON\|OFF)

1136	#
1137	# DESCRIPTION
1138	#
1139	# The DX_*_FEATURE macros control the default setting for the given
1140	# Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
1141	# generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
1142	# help (for MS users), 'CHI' for generating a seperate .chi file by the
1143	# .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
1144	# output formats. The environment variable DOXYGEN_PAPER_SIZE may be
1145	# specified to override the default 'a4wide' paper size.
1146	#
1147	# By default, HTML, PDF and PS documentation is generated as this seems to
1148	# be the most popular and portable combination. MAN pages created by
1149	# Doxygen are usually problematic, though by picking an appropriate subset
1150	# and doing some massaging they might be better than nothing. CHM and RTF
1151	# are specific for MS (note that you can't generate both HTML and CHM at
1152	# the same time). The XML is rather useless unless you apply specialized
1153	# post-processing to it.
1154	#
1155	# The macros mainly control the default state of the feature. The use can
1156	# override the default by specifying --enable or --disable. The macros
1157	# ensure that contradictory flags are not given (e.g.,
1158	# --enable-doxygen-html and --enable-doxygen-chm,
1159	# --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
1160	# feature will be automatically disabled (with a warning) if the required
1161	# programs are missing.
1162	#
1163	# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
1164	# with the following parameters: a one-word name for the project for use
1165	# as a filename base etc., an optional configuration file name (the
1166	# default is 'Doxyfile', the same as Doxygen's default), and an optional
1167	# output directory name (the default is 'doxygen-doc').
1168	#
1169	# Automake Support
1170	#
1171	# The following is a template aminclude.am file for use with Automake.
1172	# Make targets and variables values are controlled by the various
1173	# DX_COND_* conditionals set by autoconf.
1174	#
1175	# The provided targets are:
1176	#
1177	# doxygen-doc: Generate all doxygen documentation.
1178	#
1179	# doxygen-run: Run doxygen, which will generate some of the
1180	# documentation (HTML, CHM, CHI, MAN, RTF, XML)
1181	# but will not do the post processing required
1182	# for the rest of it (PS, PDF, and some MAN).
1183	#
1184	# doxygen-man: Rename some doxygen generated man pages.
1185	#
1186	# doxygen-ps: Generate doxygen PostScript documentation.
1187	#
1188	# doxygen-pdf: Generate doxygen PDF documentation.
1189	#
1190	# Note that by default these are not integrated into the automake targets.
1191	# If doxygen is used to generate man pages, you can achieve this
1192	# integration by setting man3_MANS to the list of man pages generated and
1193	# then adding the dependency:
1194	#
1195	# $(man3_MANS): doxygen-doc
1196	#
1197	# This will cause make to run doxygen and generate all the documentation.
1198	#
1199	# The following variable is intended for use in Makefile.am:
1200	#
1201	# DX_CLEANFILES = everything to clean.
1202	#
1203	# Then add this variable to MOSTLYCLEANFILES.

1647	# SYNOPSIS
1648	#
1649	# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
1650	#
1651	# DESCRIPTION
1652	#
1653	# This macro figures out how to build C programs using POSIX threads. It
1654	# sets the PTHREAD_LIBS output variable to the threads library and linker
1655	# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
1656	# flags that are needed. (The user can also force certain compiler
1657	# flags/libs to be tested by setting these environment variables.)
1658	#
1659	# Also sets PTHREAD_CC to any special C compiler that is needed for
1660	# multi-threaded programs (defaults to the value of CC otherwise). (This
1661	# is necessary on AIX to use the special cc_r compiler alias.)
1662	#
1663	# NOTE: You are assumed to not only compile your program with these flags,
1664	# but also link it with them as well. e.g. you should link with
1665	# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
1666	#
1667	# If you are only building threads programs, you may wish to use these
1668	# variables in your default LIBS, CFLAGS, and CC:
1669	#
1670	# LIBS="$PTHREAD_LIBS $LIBS"
1671	# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
1672	# CC="$PTHREAD_CC"
1673	#
1674	# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
1675	# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
1676	# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
1677	#
1678	# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
1679	# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
1680	# PTHREAD_CFLAGS.
1681	#
1682	# ACTION-IF-FOUND is a list of shell commands to run if a threads library
1683	# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
1684	# is not found. If ACTION-IF-FOUND is not specified, the default action
1685	# will define HAVE_PTHREAD.
1686	#
1687	# Please let the authors know if this macro fails on any platform, or if
1688	# you have any other suggestions or comments. This macro was based on work
1689	# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
1690	# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
1691	# Alejandro Forero Cuervo to the autoconf macro repository. We are also
1692	# grateful for the helpful feedback of numerous users.

2158	#
2159	# Of course, Automake must honor this variable whenever it calls a
2160	# tool from the auxiliary directory. The problem is that $srcdir (and
2161	# therefore $ac_aux_dir as well) can be either absolute or relative,
2162	# depending on how configure is run. This is pretty annoying, since
2163	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
2164	# source directory, any form will work fine, but in subdirectories a
2165	# relative path needs to be adjusted first.
2166	#
2167	# $ac_aux_dir/missing

2171	# fails when called from a subdirectory in a VPATH build with
2172	# a relative $ac_aux_dir
2173	#
2174	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2175	# are both prefixed by $srcdir. In an in-source build this is usually
2176	# harmless because $srcdir is `.', but things will broke when you
2177	# start a VPATH build or use an absolute $srcdir.
2178	#
2179	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
2180	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
2181	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//\(.\)"`

2187	# configure, and could therefore not use this "fixed" $ac_aux_dir.
