4 # This file is distributed under the same terms as the Autoconf macro files.

6 # Generate automatic documentation using Doxygen. Works in concert with the
7 # aminclude.m4 file and a compatible doxygen configuration file. Defines the
8 # following public macros:
9 #
10 # DX_???_FEATURE(ON|OFF) - control the default setting fo a Doxygen feature.
11 # Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
12 # 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
13 # for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',
14 # 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
15 # variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
16 # paper size.
17 #
18 # By default, HTML, PDF and PS documentation is generated as this seems to be
19 # the most popular and portable combination. MAN pages created by Doxygen are
20 # usually problematic, though by picking an appropriate subset and doing some
21 # massaging they might be better than nothing. CHM and RTF are specific for MS
22 # (note that you can't generate both HTML and CHM at the same time). The XML is
23 # rather useless unless you apply specialized post-processing to it.
24 #
25 # The macro mainly controls the default state of the feature. The use can
26 # override the default by specifying --enable or --disable. The macros ensure
27 # that contradictory flags are not given (e.g., --enable-doxygen-html and
28 # --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
29 # Finally, each feature will be automatically disabled (with a warning) if the
30 # required programs are missing.
31 #
32 # Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
33 # the following parameters: a one-word name for the project for use as a
34 # filename base etc., an optional configuration file name (the default is
35 # 'Doxyfile', the same as Doxygen's default), and an optional output directory
36 # name (the default is 'doxygen-doc').
