FeatureMap provides many utilities via its bundled bin script (or when made into a bin script via Inline Execution).

Generally, running bin/featuremap help will provide guidance on the available commands. There are a few public methods that may be of interest, too, which can be found in the source:

Check out lib/feature_map.rb to see the public API.

Check out feature_map_spec.rb to see examples of how the feature map utility is used.
