 - `-w`/`--watch` — watch files in `src/lib` for changes and rebuild the package
 - `-i`/`--input` — the input directory which contains all the files of the package. Defaults to `src/lib`
 - `-o`/`--output` — the output directory where the processed files are written to. Your `package.json`'s `exports` should point to files inside there, and the `files` array should include that folder. Defaults to `dist`

 - `--tsconfig` - the path to a tsconfig or jsconfig. When not provided, searches for the next upper tsconfig/jsconfig in the workspace path.
