 # Config file for the Cryptech Novena FPGA framework.
+#
+# At present, there are three kinds of variables in this file.
+#
+# default-section: Name of the configuration to build if the user
+#   doesn't specify one.  Only meaningful in the default section.
+#
+# cores: A list of cores to build.  Use with the --section option.
+#
+# vfiles: A list of Verilog files to include in the vfiles list when
+#   including a particular core.  All (optional) cores must have a
+#   vfiles option, so that the configuration program knows what to put
+#   into core_vfiles.mk.
