 YAKINDU Statechart Tools provide a convenient way to execute your generator while you are developing it.
 For this, you have to create a new *generator model* with the generator ID *yakindu::generic*, either by using the *New Statechart Generator Model* wizard or by simply creating a new text file with the file extension @.sgen@. The feature described below allows to configure your code generator.
