Included as part of futile is an options subsystem that facilitates the management of options for a particular application. The options.manager function produces a scoped options set within the environment, to protect against collisions with other libraries or applications. The options subsystem also provides default settings that can be restored by calling reset.options.
The 'futile.options' subsystem provides an easy user-defined options management system that is properly scoped. This means that options created via 'futile.options' are fully self-contained and will not collide with options defined in other packages. This package is a self-contained package within the futile suite of libraries.
