* Avoid running XO on older Node.js versions * xo@^0.17.0 * Split up cli.js Move the actual implementation into lib/cli.js to avoid top-level returns. xo@^0.17.0 cannot parse the file with those returns present. Throw errors from lib/cli.js and write them to stderr in cli.js before exiting. XO doesn't appreciate process.exit() calls in modules. Note that the error for invalid Babel config is now written to stderr, which seems like an improvement to me. * Actually register loud-rejectionreplace-snapshot
