+Runtime Verification
+--------------------
+
+:Manual section: 1
+
+SYNOPSIS
+========
+
+**rv** *COMMAND* [*OPTIONS*]
+
+DESCRIPTION
+===========
+
+Runtime Verification (**RV**) is a lightweight (yet rigorous) method
+for formal verification with a practical approach for complex systems.
+Instead of relying on a fine-grained model of a system (e.g., a
+re-implementation a instruction level), RV works by analyzing the trace
+of the system's actual execution, comparing it against a formal
+specification of the system behavior.
+
+The **rv** tool provides the interface for a collection of runtime
+verification (rv) monitors.
+
+COMMANDS
+========
+
+**list**
+
+        List all available monitors.
+
+**mon**
+
+        Run monitor.
+
+OPTIONS
+=======
+
+**-h**, **--help**
+
+        Display the help text.
+
+For other options, see the man page for the corresponding command.
