#!/usr/bin/env sh
# hasdata-cli installer — downloads the latest release matching the host
# OS/arch from GitHub, verifies the checksum against the published
# checksums.txt, and installs to $PREFIX (default: /usr/local/bin, or
# $HOME/.local/bin if the former is not writable).
#
# Usage:
#   curl -sSL https://raw.githubusercontent.com/HasData/hasdata-cli/main/install.sh | sh
#   curl -sSL .../install.sh | HASDATA_VERSION=v1.2.3 sh
#   curl -sSL .../install.sh | PREFIX=$HOME/bin sh
