+# Network DSC include file for [Defines] section of all Architectures.
+#
+# This file can be included to the [Defines] section of a platform DSC file by
+# using "!include NetworkPkg/NetworkDefines.dsc.inc" to set default value of
+# flags if they are not defined somewhere else, and also check the value to see
+# if there is any conflict.
+#
+# These flags can be defined before the !include line, or changed on the command
+# line to enable or disable related feature support.
+#   -D FLAG=VALUE
+# The default value of these flags are:
+#   DEFINE NETWORK_ENABLE                 = TRUE
+#   DEFINE NETWORK_SNP_ENABLE             = TRUE
+#   DEFINE NETWORK_IP4_ENABLE             = TRUE
+#   DEFINE NETWORK_IP6_ENABLE             = TRUE
