# Installs pbxray to $PREFIX/bin (default /usr/local/bin, override with
# PREFIX=~/.local ./install.sh). Downloads the release binary for your
# OS/arch (VERSION=vX.Y.Z ./install.sh for a specific one, default
# latest).
#
# This is the public installer — there's no source in this repo to fall
# back to building from (pbxray's source is closed, see LICENSE). If your
# OS/arch isn't one of the three built (linux/amd64, linux/arm64,
# darwin/arm64), there's nothing else to try.
