  1. Set showHelp return type to never 

    Since `showHelp()` calls into `process.exit()`, they should use the same return type.
The return type of `process.exit()` is `never`, not `void`. This tells the typescript compiler that code branches that have `showHelp()` terminate, and that any code written as executing after `showHelp()` should be considered dead code (similar to code after a `return` statement).
