### This script will download and build aom-av1-lavish_Endless_Merging, with possibly
### --enable-libvmaf and --enable-butteraugli. One folder will be created to clone the repo, and a python script will be downloaded.
### Only the encoder (aomenc) will be installed, no decoder nor tools.
### This script won't update things, just install. So if you want to "update",
### first change the current directory (or delete old files/folders), and the script will override existing binaries (if any).
