\f3jrunscript\fP is a command line script shell. jrunscript supports both an interactive (read\-eval\-print) mode and a batch (\-f option) mode of script execution. This is a scripting language independent shell. By default, JavaScript is the language used, but the \-l option can be used to specify a different language. Through Java to scripting language communication, jrunscript supports "exploratory programming" style.
