  17 #                 LUFA Doxygen Buildsystem Makefile Module.
  18 # -----------------------------------------------------------------------------
  19 # DESCRIPTION:
  20 #   Provides a set of targets to automatically build Doxygen documentation for
  21 #   a project (see www.doxygen.org).
  22 # -----------------------------------------------------------------------------
  23 # TARGETS:
  24 #
  25 #    doxygen                   - Build Doxygen Documentation
  26 #    doxygen_create            - Create a new Doxygen configuration file using
  27 #                                the latest template
  28 #    doxygen_upgrade           - Upgrade an existing Doxygen configuration file
  29 #                                to the latest template
  30 #
  31 # MANDATORY PARAMETERS:
  32 #
  33 #    LUFA_PATH                 - Path to the LUFA library core
  34 #
  35 # OPTIONAL PARAMETERS:
  36 #
  37 #    DOXYGEN_CONF              - Doxygen configuration filename
  38 #    DOXYGEN_FAIL_ON_WARNING   - Set to Y to fail the build on Doxygen warnings,
  39 #                                N to continue even if warnings occur
  40 #    DOXYGEN_OVERRIDE_PARAMS   - Parameters to override in the doxygen
  41 #                                configuration file
  42 # PROVIDED VARIABLES:
  43 #
  44 #    (None)
