/**
* 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.
