######### 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').

requirement tests (DX_REQUIRE_PROG). Finally, an automake flag is set and

DO-IF-ON or DO-IF-OFF are called according to the final state of the feature.
