 ## Using ParserNG as commandline tool
 You can use jar directly as commandline calculus. Unless the tool is packed to your distribution:
 ```
-java -jar parser-ng-0.1.10.jar  1+1
+java -jar parser-ng-0.1.9-release.jar  1+1

 Or as logical parser
 ```
-java -jar parser-ng-0.1.10.jar -l true and true

-java -jar parser-ng-0.1.10.jar -l "2 == (4-2)"
