1055	# DESCRIPTION
1056	#
1057	# The DX_*_FEATURE macros control the default setting for the given
1058	# Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
1059	# generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
1060	# help (for MS users), 'CHI' for generating a seperate .chi file by the
1061	# .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
1062	# output formats. The environment variable DOXYGEN_PAPER_SIZE may be
1063	# specified to override the default 'a4wide' paper size.
1064	#
1065	# By default, HTML, PDF and PS documentation is generated as this seems to
1066	# be the most popular and portable combination. MAN pages created by
1067	# Doxygen are usually problematic, though by picking an appropriate subset
1068	# and doing some massaging they might be better than nothing. CHM and RTF
1069	# are specific for MS (note that you can't generate both HTML and CHM at
1070	# the same time). The XML is rather useless unless you apply specialized
1071	# post-processing to it.
1072	#
1073	# The macros mainly control the default state of the feature. The use can
1074	# override the default by specifying --enable or --disable. The macros
1075	# ensure that contradictory flags are not given (e.g.,
1076	# --enable-doxygen-html and --enable-doxygen-chm,
1077	# --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
1078	# feature will be automatically disabled (with a warning) if the required
1079	# programs are missing.
1080	#
1081	# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
1082	# with the following parameters: a one-word name for the project for use
1083	# as a filename base etc., an optional configuration file name (the
1084	# default is 'Doxyfile', the same as Doxygen's default), and an optional
1085	# output directory name (the default is 'doxygen-doc').
1086	#
1087	# Automake Support
1088	#
1089	# The following is a template aminclude.am file for use with Automake.
1090	# Make targets and variables values are controlled by the various
1091	# DX_COND_* conditionals set by autoconf.
1092	#
1093	# The provided targets are:
1094	#
1095	# doxygen-doc: Generate all doxygen documentation.
1096	#
1097	# doxygen-run: Run doxygen, which will generate some of the
1098	# documentation (HTML, CHM, CHI, MAN, RTF, XML)
1099	# but will not do the post processing required
1100	# for the rest of it (PS, PDF, and some MAN).
1101	#
1102	# doxygen-man: Rename some doxygen generated man pages.
1103	#
1104	# doxygen-ps: Generate doxygen PostScript documentation.
1105	#
1106	# doxygen-pdf: Generate doxygen PDF documentation.
1107	#
1108	# Note that by default these are not integrated into the automake targets.
1109	# If doxygen is used to generate man pages, you can achieve this
1110	# integration by setting man3_MANS to the list of man pages generated and
1111	# then adding the dependency:
1112	#
1113	# $(man3_MANS): doxygen-doc
1114	#
1115	# This will cause make to run doxygen and generate all the documentation.
1116	#
1117	# The following variable is intended for use in Makefile.am:
1118	#
1119	# DX_CLEANFILES = everything to clean.
1120	#
1121	# Then add this variable to MOSTLYCLEANFILES.

1603	# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

1605	# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
1606	#
1607	# Of course, Automake must honor this variable whenever it calls a
1608	# tool from the auxiliary directory. The problem is that $srcdir (and
1609	# therefore $ac_aux_dir as well) can be either absolute or relative,
1610	# depending on how configure is run. This is pretty annoying, since
1611	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
1612	# source directory, any form will work fine, but in subdirectories a
1613	# relative path needs to be adjusted first.
1614	#
1615	# $ac_aux_dir/missing
1616	# fails when called from a subdirectory if $ac_aux_dir is relative
1617	# $top_srcdir/$ac_aux_dir/missing
1618	# fails if $ac_aux_dir is absolute,
1619	# fails when called from a subdirectory in a VPATH build with
1620	# a relative $ac_aux_dir
1621	#
1622	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1623	# are both prefixed by $srcdir. In an in-source build this is usually
1624	# harmless because $srcdir is `.', but things will broke when you
1625	# start a VPATH build or use an absolute $srcdir.
1626	#
1627	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1628	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
1629	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//\(.\)"`
1630	# and then we would define $MISSING as
1631	# MISSING="\${SHELL} $am_aux_dir/missing"
1632	# This will work as long as MISSING is not called from configure, because
1633	# unfortunately $(top_srcdir) has no meaning in configure.
1634	# However there are other variables, like CC, which are often used in
1635	# configure, and could therefore not use this "fixed" $ac_aux_dir.
1636	#
1637	# Another solution, used here, is to always expand $ac_aux_dir to an
1638	# absolute PATH. The drawback is that using absolute paths prevent a
