+# DESCRIPTION
+# This build definition file sets the ADRS_MACROS and ADRS_DEFINE build macros.
+#
+# The ADRS_MACROS build macro list the build macros the kernel configuration
+# tool will have to get from cdf files, and write in the kernel configuration
+# Makefile.
+#
+# The ADRS_DEFINE build macros is part of the CC_DEFINES, and is passed to the
+# compilers as a definition macro
