+# be the Doxyfile to use and the next prerequisites the input files.  You
+# can override Doxyfile configuration variables by defining a DOXYGEN_VARS
+# Make variable for this rule.  For example, defining:
+# PROJECT_NAME := myproj
+# DOXYGEN_VARS := PROJECT_NAME
+# You can override Doxygen's PROJECT_NAME configuration option. Optionally, you
+# can define DOXYGEN_VARS_PREFIX too, to avoid polluting your Makefile with
+# Doxygen variables.  For example:
+# DOXY.PROJECT_NAME := myproj
+# DOXYGEN_VARS_PREFIX := DOXY.
+# DOXYGEN_VARS := PROJECT_NAME
+# This rule might be still a little restrictive, but you can always make your
