System Language is an Applescript extension that allows a scripter to determine what language is being used by the system on which the script is running.

A numerical language code, or the name of the language in plain text is returned based on how System language is called by the scripter. One possible use of System Language might be to allow scripts to automatically detect and adjust to running on systems in different languages.
