 Specify the `tsconfig` that the program should use. If not provided, it defaults
 to `tsconfig.json`.

 Specify the source directory. If not provided, it defaults to `./src`.

 Specify the output directory of the compiled code where `resolve-tspaths` should
 perform its changes. If not provided, it will default to
 `compilerOptions.outDir` from your `tsconfig`.
 
-#### `--ext`

 Provide a comma separated list of file extensions in the output directory that
 the program should process. Defaults to `js,d.ts`, which will process `.js` and
