                                    BeanShell is a small, free, embeddable Java source interpreter
    with object scripting language features, written in Java. BeanShell
    dynamically executes standard Java syntax and extends it with common
    scripting conveniences such as loose types, commands, and method closures
    like those in Perl and JavaScript.
