This just adds an additional make target (`make test-node-inspect`) but
will not include the new debugger in releases.

+ * 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.
