RunWM is an ancient and horrendous script that was once used to kill baby seals. Recently, we have been contacted by PETA about this, and in an effort to comply with federal wildlife regulations, we are planning on removing RunWM. I've done a preliminary search, and have not been able to find any packages that depend on this script explicitly in Core. It is possible something else may explicitly require it, but if that is true, it is time to fix everything to NOT require it. If you know of any package in Core that requires RunWM which I'm not seeing, please speak now. Outside of Core, let the maintainer of the software know that RunWM is going away. THINK OF THE CUTE BABY SEALS!
