+# * DX_ARG_ABLE : new variable 'DX_FLAG_DX_CURRENT_FEATURE'\r
+# * DX_CLEAR_DEPEND : use of explicit variable 'DX_FLAG_DX_CURRENT_FEATURE'\r
+# in AC_SUBST instead of 'DX_FLAG[]DX_CURRENT_FEATURE' which is rejected by\r
+# newer autotools \r
+\r
+# Generate automatic documentation using Doxygen. Works in concert with the\r
+# aminclude.m4 file and a compatible doxygen configuration file. Defines the\r
+# following public macros:\r
+#\r
+# DX_???_FEATURE(ON|OFF) - control the default setting fo a Doxygen feature.\r
+# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,\r
+# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'\r
+# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',\r
+# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment\r
+# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'\r
+# paper size.\r
+#\r
+# By default, HTML, PDF and PS documentation is generated as this seems to be\r
+# the most popular and portable combination. MAN pages created by Doxygen are\r
+# usually problematic, though by picking an appropriate subset and doing some\r
+# massaging they might be better than nothing. CHM and RTF are specific for MS\r
+# (note that you can't generate both HTML and CHM at the same time). The XML is\r
+# rather useless unless you apply specialized post-processing to it.\r
+#\r
+# The macro mainly controls the default state of the feature. The use can\r
+# override the default by specifying --enable or --disable. The macros ensure\r
+# that contradictory flags are not given (e.g., --enable-doxygen-html and\r
+# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)\r
+# Finally, each feature will be automatically disabled (with a warning) if the\r
+# required programs are missing.\r
+#\r
+# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with\r
+# the following parameters: a one-word name for the project for use as a\r
+# filename base etc., an optional configuration file name (the default is\r
+# 'Doxyfile', the same as Doxygen's default), and an optional output directory\r
+# name (the default is 'doxygen-doc').\r
