/** High-level view of the verified application, from the model-checker POV

- * algorithms to control the execution of the model-checked process
- * and the exploration of the execution graph. Model-checking
- * algorithms should be able to be written in high-level languages
- * (e.g. Python) using bindings on this interface.
+ * This is expected to become the interface used by model-checking algorithms to control the execution of
+ * the application process during the exploration of the execution graph.
+ *
+ * One day, this will allow parallel exploration, ie, the handling of several application processes (each encapsulated
+ * in a separate CheckerSide objects) that explore several parts of the exploration graph.
