    Commands:

      lint                  List changes you need to make (always recommended)
        Example: apos-code-upgrader lint
      upgrade [options]     Make some changes automatically
        Example: apos-code-upgrader upgrade
        Options:
        - --upgrade-required-files: Experimental support for inlining module
          code included with \`require\` statements. Most successful when the
          inlined file is limited to an exported function that the module
          invokes with \`(self, options)\`
  `);
} else {
  console.log(stripIndent`
    Run \`apos-code-upgrader help\` or \`apos-code-upgrader --help\` for commands.

      Running the upgrade command will make MAJOR changes to your code. It will not (git) commit those changes, however.
