SCUMM meaning in Softwares ?

Script Creation Utility for Maniac Mansion (SCUMM) is a video game engine developed at Lucasfilm Games, later renamed LucasArts, to ease development on their graphic adventure game Maniac Mansion (1987). It was subsequently used as the engine for later LucasArts adventure games.

It falls somewhere between a game engine and a programming language, allowing designers to create locations, items and dialogue sequences without writing code in the language in which the game source code ends up. This also allowed the game's script and data files to be cross-platform, i.e., re-used across various platforms. SCUMM is also a host for embedded game engines such as the Interactive MUsic Streaming Engine (iMUSE), the INteractive Streaming ANimation Engine (INSANE), CYST (in-game animation engine), FLEM (places and names object inside a room), and MMUCAS. SCUMM has been released on these platforms: 3DO, Amiga, Apple II, Atari ST, CDTV, Commodore 64, Fujitsu FM Towns & Marty, Apple Macintosh, Nintendo Entertainment System, DOS, Microsoft Windows, Sega CD (Mega-CD), and TurboGrafx-16/PC Engine.
