 When building a bundleless project where source files exist across multiple directories, the output directory structure will be replicated relative to the `outBase` directory in the output directory. If no base output directory is specified, the [lowest common ancestor](https://en.wikipedia.org/wiki/Lowest_common_ancestor) of all input entry points is used by default.
