# This script ensures that a command is run only if it hasn't been run before with given arguments, set of dependent files,
# and specified input values.
# It uses a hash of the command, arguments, input values, and dependent files to determine if the command needs to be run.
# Only successful executions are cached.
# This is useful for running commands that are expensive to run multiple times, such as building a project or running a test suite.
# Usage:
# idempotently <dependent_files> // <input_values> -- <command> <arguments>
# Example:
