+>SDL provides several cross-platform functions for dealing with time.
+It provides a way to get the current time, a way to wait a little while,
+and a simple timer mechanism.  These functions give you two ways of moving an
+object every x milliseconds:

+><P
+>Use a timer callback function.  This may have the bad effect that it runs in a seperate thread or uses alarm signals, but it's easier to implement.</P
