+/* This header defines a number of "unsafe" operations on Chipmunk objects.
+ * In this case "unsafe" is referring to operations which may reduce the
+ * physical accuracy or numerical stability of the simulation, but will not
+ * cause crashes.
+ *
+ * The prime example is mutating collision shapes. Chipmunk does not support
+ * this directly. Mutating shapes using this API will caused objects in contact
+ * to be pushed apart using Chipmunk's overlap solver, but not using real
+ * persistent velocities. Probably not what you meant, but perhaps close enough.

+/// @defgroup unsafe Chipmunk Unsafe Shape Operations
+/// These functions are used for mutating collision shapes.
+/// Chipmunk does not have any way to get velocity information on changing shapes,
+/// so the results will be unrealistic. You must explicity include the chipmunk_unsafe.h header to use them.
