rhino is a start script for the rhino JavaScript shell which provides a simple way to run scripts in batch mode or an interactive environ-
ment for exploratory programming.
OPTIONS
-e script_source
Executes script_source as a JavaScript script.
-f script_filename_or_url
Reads script_filename_or_url content and execute it as a JavaScript script.
-opt, -O optLevel
Optimizes at level optLevel, which must be an integer between 0 and 9.
-version versionNumber
Specifies the language version to compile with. The string versionNumber must be one of 100, 110, 120, 130, or 140. See JavaScript

The arguments object is an array containing the strings of all the arguments given at the command line when the shell was invoked.
help() Executing the help function will print usage and help messages.

extension.

plied, it is expected to be one of 100, 110, 120, 130, or 140 to indicate JavaScript version 1.0, 1.1, 1.2, 1.3, or 1.4 respec-
tively.
