 #
 # Usage:
 # $ ./generate_gni.sh [--disable-avx] [--only-configs]
 #
 # The following optional flags are supported:
 # --disable-avx : AVX+AVX2 support is disabled.
-# --only-configs: Excludes generation of GN and GYP files (i.e. only
-#                 configuration headers are generated).
+# --only-configs : Excludes generation of GN and GYP files (i.e. only
+#                  configuration headers are generated).
+# --enable-vp9-highbitdepth : Allow for high bit depth internal, 10 and 12 bit
+#                             vp9 encode and decode. Only applied to x86[_64].
