+"""
+Generator for the Mutual Exclusion (Mutex) benchmark.
+
+Produces a reaction system modelling N processes competing for
+exclusive access to a critical section, using activation signals,
+request tokens, and a lock. Generates one of three RSCTL properties.
+
+NOTE: generates old-syntax input (context-entities, initial-contexts,
+rsctl-property) which is not compatible with the current parser.
