/**
 * Usage:
 *   test-npm-package.js [--install] [--rebuild] <source> <test-arg>+
 *
 * Everything after the <source> directory gets passed to `npm run` to build
 * the test command.
 *
 * If `--install` is passed, we'll run a full `npm install` before running the
 * test suite. Same for `--rebuild` and `npm rebuild`.
 *
 * We always use the node used to spawn this script and the `npm` version
 * bundled in `deps/npm`.
 *
 * If an additional `--logfile=<filename>` option is passed before `<source>`,
 * the stdout output of the test script will be written to that file.
