	Usage
	  $ mwts <verb> [<file>...] [options]

    Verb can be:
      init        Adds default npm scripts to your package.json.
      lint        Checks code for formatting and lint issues.
      check       Alias for lint. Kept for backward compatibility.
      fix         Fixes formatting and linting issues (if possible).
      clean       Removes all files generated by the build.

  Options
    --help        Prints this help message.
    -y, --yes     Assume a yes answer for every prompt.
    -n, --no      Assume a no answer for every prompt.
    --dry-run     Don't make any actual changes.
    --yarn        Use yarn instead of npm.

	Examples
    $ mwts init -y
    $ mwts lint
    $ mwts fix
    $ mwts fix src/file1.ts src/file2.ts
    $ mwts clean`,
    flags: {
        help: { type: 'boolean' },
        yes: { type: 'boolean', alias: 'y' },

        dryRun: { type: 'boolean' },
