7/// A builder to use for local development to create an `OptionsWatcher` which changes the underlying `OptionsProvider` when files are changed.
8///
9/// This builder is kept separate from the `OptionsProviderBuilder` in order to keep `OptionsProviderBuilder` and `OptionsProvider` as simple and efficient as possible for production use.
10///
11/// ⚠️ Development in progress ⚠️\
12/// Not truly considered public yet and mainly available to support bindings for other languages.
