# This script can be used to test the 'install.sh' and 'verify'sh'
# scripts locally without running the 3pp LUCI recipe.
# Usage:
#    ./test_locally.sh <BINARY> [<VERSION>]
#
# Where <BINARY> points to the real tool binary..
#
# Where <VERSION> is the 3pp version for said binary,
# (extracted from `<tool> --version` by default).
#
# E.g.:
#    # Download latest binary
#    ./test_locall.sh
#
#    # Test a given binary download on the local machine
#    ./test_locally.sh /path/to/buildifier-linux-amd64
#
#    # Check with a custom _3PP_VERSION value
#    ./test_locally.sh /path/to/buildifier-linux-amd64 5.1.0-fuchsia1
