# Copyright (C) 2004 Oren Ben-Kiki
# This file is distributed under the same terms as the Automake macro files.

# Generate automatic documentation using Doxygen. Goals and variables values
# are controlled by the various DX_COND_??? conditionals set by autoconf.
#
# The provided goals 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 goals. 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.
#
# This is usually added to MOSTLYCLEANFILES.
