1.8 +
1.9 +# Generate automatic documentation using Doxygen. Works in concert with the
1.10 +# aminclude.m4 file and a compatible doxygen configuration file. Defines the
1.11 +# following public macros:
1.12 +#
1.13 +# DX_???_FEATURE(ON|OFF) - control the default setting fo a Doxygen feature.
1.14 +# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
1.15 +# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
1.16 +# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',
1.17 +# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
1.18 +# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
1.19 +# paper size.
1.20 +#
1.21 +# By default, HTML, PDF and PS documentation is generated as this seems to be
1.22 +# the most popular and portable combination. MAN pages created by Doxygen are
1.23 +# usually problematic, though by picking an appropriate subset and doing some
1.24 +# massaging they might be better than nothing. CHM and RTF are specific for MS
1.25 +# (note that you can't generate both HTML and CHM at the same time). The XML is
1.26 +# rather useless unless you apply specialized post-processing to it.
1.27 +#
1.28 +# The macro mainly controls the default state of the feature. The use can
1.29 +# override the default by specifying --enable or --disable. The macros ensure
1.30 +# that contradictory flags are not given (e.g., --enable-doxygen-html and
1.31 +# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
1.32 +# Finally, each feature will be automatically disabled (with a warning) if the
1.33 +# required programs are missing.
1.34 +#
1.35 +# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
1.36 +# the following parameters: a one-word name for the project for use as a
1.37 +# filename base etc., an optional configuration file name (the default is
1.38 +# 'Doxyfile', the same as Doxygen's default), and an optional output directory
1.39 +# name (the default is 'doxygen-doc').
