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 macros mainly control 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'). +# +# Automake Support +# +# The following is a template aminclude.am file for use with Automake. +# Make targets and variables values are controlled by the various +# DX_COND_* conditionals set by autoconf. +# +# The provided targets are: +# +# doxygen-doc: Generate all doxygen documentation. +# +# doxygen-run: Run doxygen, which will generate some of the +# documentation (HTML, CHM, CHI, MAN, RTF, XML) +# but will not do the post processing required +# for the rest of it (PS, PDF, and some MAN). +# +# doxygen-man: Rename some doxygen generated man pages. +# +# doxygen-ps: Generate doxygen PostScript documentation. +# +# doxygen-pdf: Generate doxygen PDF documentation. +# +# Note that by default these are not integrated into the automake targets. +# If doxygen is used to generate man pages, you can achieve this +# integration by setting man3_MANS to the list of man pages generated and +# then adding the dependency: +# +# $(man3_MANS): doxygen-doc +# +# This will cause make to run doxygen and generate all the documentation. +# +# The following variable is intended for use in Makefile.am: +# +# DX_CLEANFILES = everything to clean. +# +# Then add this variable to MOSTLYCLEANFILES. +# +# ----- begin aminclude.am ------------------------------------- +# +# ## --------------------------------- ## +# ## Format-independent Doxygen rules. ## +# ## --------------------------------- ## +# +# if DX_COND_doc +# +# ## ------------------------------- ## +# ## Rules specific for HTML output. ## +# ## ------------------------------- ## +# +# if DX_COND_html +# +# DX_CLEAN_HTML = @DX_DOCDIR@/html +# +# endif DX_COND_html +# +# ## ------------------------------ ## +# ## Rules specific for CHM output. ## +# ## ------------------------------ ## +# +# if DX_COND_chm +# +# DX_CLEAN_CHM = @DX_DOCDIR@/chm +# +# if DX_COND_chi +# +# DX_CLEAN_CHI = @DX_DOCDIR@/@PACKAGE@.chi +# +# endif DX_COND_chi +# +# endif DX_COND_chm +# +# ## ------------------------------ ## +# ## Rules specific for MAN output. ## +# ## ------------------------------ ## +# +# if DX_COND_man +# +# DX_CLEAN_MAN = @DX_DOCDIR@/man +# +# endif DX_COND_man +# +# ## ------------------------------ ## +# ## Rules specific for RTF output. ## +# ## ------------------------------ ## +# +# if DX_COND_rtf +# +# DX_CLEAN_RTF = @DX_DOCDIR@/rtf +# +# endif DX_COND_rtf +# +# ## ------------------------------ ## +# ## Rules specific for XML output. ## +# ## ------------------------------ ## +# +# if DX_COND_xml +# +# DX_CLEAN_XML = @DX_DOCDIR@/xml +# +# endif DX_COND_xml +# +# ## ----------------------------- ## +# ## Rules specific for PS output. ## +# ## ----------------------------- ## +# +# if DX_COND_ps +# +# DX_CLEAN_PS = @DX_DOCDIR@/@PACKAGE@.ps +# +# DX_PS_GOAL = doxygen-ps +# +# doxygen-ps: @DX_DOCDIR@/@PACKAGE@.ps +# +# @DX_DOCDIR@/@PACKAGE@.ps: @DX_DOCDIR@/@PACKAGE@.tag +# cd @DX_DOCDIR@/latex;
