  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.
