The German Wikipedia says:
Aus architektonischer Sicht werden
Skriptsprachen verwendet, um aus
bestehenden Komponenten ein
Anwendungsprogramm zu bauen. Die
Komponenten selbst werden in einer
Programmiersprache entwickelt.
Translation:
From an architectural point of view, script languages are used to
build an application program from
existing components. The components
themselves are developed using
programming languages.
Script languages use components that are already there to make programs. These components are written in programming languages. :)
Think about shell scripting... There you use little programs "mostly" written in C.
