/*
 * akglfile -- file scope.
 *
 * The block is a run of top-level declarations: a movementlogicfunc, a backend
 * vtable, a static table. All this prelude supplies is the include set, so the
 * chapter does not have to spend six lines on `#include` before showing the one
 * function it is about.
 *
 * There is no akglfile.post. Nothing has to be closed.
