 #
 # 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

+# --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.

for now we only want to do this for x86 where we have comparable performance for
8-bit decodes between the two configs.
