# Build eval-cli for x86_64 Linux from any host (macOS, Linux, etc.)
# using Docker. The resulting binary is placed at the path printed on
# completion (default: target/eval-cli).
#
# Usage:
#   crates/eval_cli/script/build-linux [--output PATH]
#
# Examples:
#   crates/eval_cli/script/build-linux
#   crates/eval_cli/script/build-linux --output ~/bin/eval-cli
#
# Prerequisites: Docker must be installed and running.
