# This script is used to generate .gni files and files in the

# 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).
# --enable-vp9-highbitdepth : Allow for high bit depth internal, 10 and 12 bit
# vp9 encode and decode. Only applied to x86[_64].
