     19 # DESCRIPTION
     20 #
     21 #   The DX_*_FEATURE macros control the default setting for the given
     22 #   Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
     23 #   generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
     24 #   help (for MS users), 'CHI' for generating a separate .chi file by the
     25 #   .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
     26 #   output formats. The environment variable DOXYGEN_PAPER_SIZE may be
     27 #   specified to override the default 'a4wide' paper size.
     28 #
     29 #   By default, HTML, PDF and PS documentation is generated as this seems to
     30 #   be the most popular and portable combination. MAN pages created by
     31 #   Doxygen are usually problematic, though by picking an appropriate subset
     32 #   and doing some massaging they might be better than nothing. CHM and RTF
     33 #   are specific for MS (note that you can't generate both HTML and CHM at
     34 #   the same time). The XML is rather useless unless you apply specialized
     35 #   post-processing to it.
     36 #
     37 #   The macros mainly control the default state of the feature. The use can
     38 #   override the default by specifying --enable or --disable. The macros
     39 #   ensure that contradictory flags are not given (e.g.,
     40 #   --enable-doxygen-html and --enable-doxygen-chm,
     41 #   --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
     42 #   feature will be automatically disabled (with a warning) if the required
     43 #   programs are missing.
     44 #
     45 #   Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
     46 #   with the following parameters: a one-word name for the project for use
     47 #   as a filename base etc., an optional configuration file name (the
     48 #   default is '$(srcdir)/Doxyfile', the same as Doxygen's default), and an
     49 #   optional output directory name (the default is 'doxygen-doc'). To run
     50 #   doxygen multiple times for different configuration files and output
     51 #   directories provide more parameters: the second, forth, sixth, etc
     52 #   parameter are configuration file names and the third, fifth, seventh,
     53 #   etc parameter are output directories. No checking is done to catch
     54 #   duplicates.
     55 #
     56 #   Automake Support
     57 #
     58 #   The DX_RULES substitution can be used to add all needed rules to the
     59 #   Makefile. Note that this is a substitution without being a variable:
     60 #   only the @DX_RULES@ syntax will work.
     61 #
     62 #   The provided targets are:
     63 #
     64 #     doxygen-doc: Generate all doxygen documentation.
     65 #
     66 #     doxygen-run: Run doxygen, which will generate some of the
     67 #                  documentation (HTML, CHM, CHI, MAN, RTF, XML)
     68 #                  but will not do the post processing required
     69 #                  for the rest of it (PS, PDF).
     70 #
     71 #     doxygen-ps:  Generate doxygen PostScript documentation.
     72 #
     73 #     doxygen-pdf: Generate doxygen PDF documentation.
     74 #
     75 #   Note that by default these are not integrated into the automake targets.
     76 #   If doxygen is used to generate man pages, you can achieve this
     77 #   integration by setting man3_MANS to the list of man pages generated and
     78 #   then adding the dependency:
     79 #
     80 #     $(man3_MANS): doxygen-doc
     81 #
     82 #   This will cause make to run doxygen and generate all the documentation.
     83 #
     84 #   The following variable is intended for use in Makefile.am:
     85 #
     86 #     DX_CLEANFILES = everything to clean.
     87 #
     88 #   Then add this variable to MOSTLYCLEANFILES.
