# ScriptError < Exception (from ruby core) --- ScriptError is the superclass for errors raised when a script can not be executed because of a `LoadError`, `NotImplementedError` or a `SyntaxError`. Note these type of `ScriptErrors` are not `StandardError` and will not be rescued unless it is specified explicitly (or its ancestor `Exception`). ---
