Write your Open Type features using the Adobe feature syntax in the UFO file. See also Tal Leming's Open Type Cookbook.
Note: If you are using Kern center or MetricsMachine, your kerning is added automatically to the features, you should not define a kerning feature here. If you have defined a kern feature in the feature file, then this will be used instead of the kerning set in the UFO file.
