Is that a convention, or just what they stand for? (Do the window manager and the menu suck, because they don't have the "s" prefix? Is st static because it doesn't have the "d" prefix? Why do we abbreviate "terminal" but not "menu" / why not follow the established abbreviation of "term" as in xterm, dtterm, eterm, etc.? How come the "s" prefix in sprop and sselp stands for "simple" instead of "suckless"?)
