public static void main(java.lang.String[] args)
                 throws java.lang.Exception
```
    Test application for JexlScriptEngine (JSR-223 implementation).
    If a single argument is present, it is treated as a file name of a JEXL script to be evaluated. Any exceptions terminate the application.
    Otherwise, lines are read from standard input and evaluated. ScriptExceptions are logged, and do not cause the application to exit. This is done so that interactive testing is easier. The line //q! ends the loop.
    
    Parameters:
    
    args - (optional) file name to evaluate. Stored in the args variable.
    
    Throws:
    
    java.lang.Exception - if parsing or IO fail
  - run
