867	# DX_DOT_FEATURE(ON\|OFF)

875	# DX_PS_FEATURE(ON\|OFF)
876	#
877	# DESCRIPTION
878	#
879	# The DX_*_FEATURE macros control the default setting for the given
880	# Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
881	# generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
882	# help (for MS users), 'CHI' for generating a seperate .chi file by the
883	# .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
884	# output formats. The environment variable DOXYGEN_PAPER_SIZE may be
885	# specified to override the default 'a4wide' paper size.
886	#
887	# By default, HTML, PDF and PS documentation is generated as this seems to
888	# be the most popular and portable combination. MAN pages created by
889	# Doxygen are usually problematic, though by picking an appropriate subset
890	# and doing some massaging they might be better than nothing. CHM and RTF
891	# are specific for MS (note that you can't generate both HTML and CHM at
892	# the same time). The XML is rather useless unless you apply specialized
893	# post-processing to it.
894	#
895	# The macros mainly control the default state of the feature. The use can
896	# override the default by specifying --enable or --disable. The macros
897	# ensure that contradictory flags are not given (e.g.,
898	# --enable-doxygen-html and --enable-doxygen-chm,
899	# --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
900	# feature will be automatically disabled (with a warning) if the required
901	# programs are missing.
902	#
903	# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
904	# with the following parameters: a one-word name for the project for use
905	# as a filename base etc., an optional configuration file name (the
906	# default is 'Doxyfile', the same as Doxygen's default), and an optional
907	# output directory name (the default is 'doxygen-doc').
908	#
909	# Automake Support
910	#
911	# The following is a template aminclude.am file for use with Automake.
912	# Make targets and variables values are controlled by the various
913	# DX_COND_* conditionals set by autoconf.
914	#
915	# The provided targets are:
916	#
917	# doxygen-doc: Generate all doxygen documentation.
918	#
919	# doxygen-run: Run doxygen, which will generate some of the
920	# documentation (HTML, CHM, CHI, MAN, RTF, XML)
921	# but will not do the post processing required
922	# for the rest of it (PS, PDF, and some MAN).
923	#
924	# doxygen-man: Rename some doxygen generated man pages.
925	#
926	# doxygen-ps: Generate doxygen PostScript documentation.
927	#
928	# doxygen-pdf: Generate doxygen PDF documentation.
929	#
930	# Note that by default these are not integrated into the automake targets.
931	# If doxygen is used to generate man pages, you can achieve this
932	# integration by setting man3_MANS to the list of man pages generated and
933	# then adding the dependency:
934	#
935	# $(man3_MANS): doxygen-doc
936	#
937	# This will cause make to run doxygen and generate all the documentation.
938	#
939	# The following variable is intended for use in Makefile.am:
940	#
941	# DX_CLEANFILES = everything to clean.
942	#
943	# Then add this variable to MOSTLYCLEANFILES.

1387	# SYNOPSIS
1388	#
1389	# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
1390	#
1391	# DESCRIPTION
1392	#
1393	# This macro figures out how to build C programs using POSIX threads. It
1394	# sets the PTHREAD_LIBS output variable to the threads library and linker
1395	# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
1396	# flags that are needed. (The user can also force certain compiler
1397	# flags/libs to be tested by setting these environment variables.)
1398	#
1399	# Also sets PTHREAD_CC to any special C compiler that is needed for
1400	# multi-threaded programs (defaults to the value of CC otherwise). (This
1401	# is necessary on AIX to use the special cc_r compiler alias.)
1402	#
1403	# NOTE: You are assumed to not only compile your program with these flags,
1404	# but also link it with them as well. e.g. you should link with
1405	# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
1406	#
1407	# If you are only building threads programs, you may wish to use these
1408	# variables in your default LIBS, CFLAGS, and CC:
1409	#
1410	# LIBS="$PTHREAD_LIBS $LIBS"
1411	# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
1412	# CC="$PTHREAD_CC"
1413	#
1414	# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
1415	# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
1416	# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
1417	#
1418	# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
1419	# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
1420	# PTHREAD_CFLAGS.
1421	#
1422	# ACTION-IF-FOUND is a list of shell commands to run if a threads library
1423	# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
1424	# is not found. If ACTION-IF-FOUND is not specified, the default action
1425	# will define HAVE_PTHREAD.
1426	#
1427	# Please let the authors know if this macro fails on any platform, or if
1428	# you have any other suggestions or comments. This macro was based on work
1429	# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
1430	# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by

1983	#
1984	# Of course, Automake must honor this variable whenever it calls a

1986	# therefore $ac_aux_dir as well) can be either absolute or relative,
1987	# depending on how configure is run. This is pretty annoying, since
1988	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
1989	# source directory, any form will work fine, but in subdirectories a
1990	# relative path needs to be adjusted first.
1991	#
1992	# $ac_aux_dir/missing
1993	# fails when called from a subdirectory if $ac_aux_dir is relative
1994	# $top_srcdir/$ac_aux_dir/missing
1995	# fails if $ac_aux_dir is absolute,
1996	# fails when called from a subdirectory in a VPATH build with
1997	# a relative $ac_aux_dir
1998	#
1999	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2000	# are both prefixed by $srcdir. In an in-source build this is usually
2001	# harmless because $srcdir is '.', but things will broke when you
2002	# start a VPATH build or use an absolute $srcdir.
2003	#
2004	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
2005	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
2006	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//\(.\)"`
2007	# and then we would define $MISSING as
2008	# MISSING="\${SHELL} $am_aux_dir/missing"

2012	# configure, and could therefore not use this "fixed" $ac_aux_dir.
