- MODULE R_DEFAULTS
-
- This module uses the R_Behaviour module to define convient and
- easy to use behaviours. These aren't very sophistated, but they
- can be used to quickly animate a movie. For more sophistated
- animation, a similiar library of sophistocated personnalized
- functions can be created.
