maria - 1.3.5-4.1+b2 main

Maria is a powerful tool designed to aid engineers in modelling and
solving concurrency related problems in parallel and distributed
computing systems.
.
Maria finds deadlocks and violations against safety or liveness
requirements by exploring all states that can be reached from the
initial state of a system. The tool manages tens or hundreds of
millions of reachable states and enabled actions.
.
The expressive power of Maria's formalism is close to high-level
programming languages, thanks to its rich data type system and
powerful algebraic operations.
