Here we are trying to gather all sorts of information we have about the SCUMM/SPUTM engine.
This needs to be extended. A lot of information can be found directly in the ScummVM source, the heads of its developers, and the external links I found below. Feel free to try and tap each of these sources to gain more information and add it here (note: no brain surgery recommended. For external sources, permission from the authors should be recieved before blatantly copying stuff).
