+      SMC (State Machine Compiler) takes a text input file describing states,
+      events and actions of a state machine and generates source code that
+      implements the state machine.
+
+      SMC supports many target languages:
+      C, C++, DotNet, Groovy, java, Java, JavaScript, Lua, ObjC, Perl, Php,
+      Python, Ruby, Scala, Tcl.
+
+      SMC can also generate GraphViz state diagrams from the input file.
