########## CHANGELOG ##################
# 2009-01-14 Martin Mann
# * DX_ARG_ABLE : new variable 'DX_FLAG_DX_CURRENT_FEATURE'
# * DX_CLEAR_DEPEND : use of explicit variable 'DX_FLAG_DX_CURRENT_FEATURE'
# in AC_SUBST instead of 'DX_FLAG[]DX_CURRENT_FEATURE' which is rejected by
# newer autotools
# Generate automatic documentation using Doxygen. Works in concert with the
# aminclude.m4 file and a compatible doxygen configuration file. Defines the
# following public macros:
#
# DX_???_FEATURE(ON|OFF) - control the default setting fo a Doxygen feature.
# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',
# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
# paper size.
#
# By default, HTML, PDF and PS documentation is generated as this seems to be
# the most popular and portable combination. MAN pages created by Doxygen are
# usually problematic, though by picking an appropriate subset and doing some
# massaging they might be better than nothing. CHM and RTF are specific for MS
# (note that you can't generate both HTML and CHM at the same time). The XML is
# rather useless unless you apply specialized post-processing to it.
#
# The macro mainly controls the default state of the feature. The use can
# override the default by specifying --enable or --disable. The macros ensure
# that contradictory flags are not given (e.g., --enable-doxygen-html and
# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
# Finally, each feature will be automatically disabled (with a warning) if the
# required programs are missing.
#
# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
# the following parameters: a one-word name for the project for use as a
# filename base etc., an optional configuration file name (the default is
# 'Doxyfile', the same as Doxygen's default), and an optional output directory
# name (the default is 'doxygen-doc').
