stack exec espial
```
see `config/settings.yml` for changing default run-time parameters / environment variables
### Configuration
default app http port: `3000`
See `config/settings.yml` for changing default run-time parameters & environment variables.
- `config/settings.yml` is embedded into the app executable when compiled, so after changing `config/settings.yml`, run `stack build` again to apply the new settings.
- `config/settings.yml` values formatted like `_env:ENV_VAR_NAME:default_value` can be
overridden by the specified environment variable.
- Example
- `_env:PORT:3000`
- environment variable `PORT`
- default app http port: `3000`
