This manual describes MONA version 1.4. Section 1 contains an introductory example and a brief description of MONA applications. In Section 2, the basic features of the MONA tool are described through a number of examples. Section 3 discusses the automaton-logic connection and the MONA compilation semantics. Section 4 describes DAGification, formula reduction, and separate compilation. In Section 5, it is shown how to make MONA produce detailed information about the processing and the resulting automata. Section 6 describes some more advanced constructs, such as, exporting and importing automata, controlling restrictions, and emulating Presburger arithmetic and M2L-Str. In Section 7, the decision procedure for WS2S is presented along with the MONA concept of Guided Tree Automata and an extension with recursive types. Section 8 discusses our plans for future work. In the appendices, the full syntax is defined, the command-line usage of MONA is shown, and the MONA DFA, GTA, and BDD packages are described.
