+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+All message digests (MDs) go through a number of stages in their life-cycle:
+.IP start 4
+.IX Item "start"
+This state represents the MD before it has been allocated.  It is the
+starting state for any life-cycle transitions.
+.IP newed 4
+.IX Item "newed"
+This state represents the MD after it has been allocated.
+.IP initialised 4
+.IX Item "initialised"
+This state represents the MD when it is set up and capable of processing
+input.
+.IP updated 4
+.IX Item "updated"
+This state represents the MD when it is set up and capable of processing
+additional input or generating output.
+.IP finaled 4
+.IX Item "finaled"
+This state represents the MD when it has generated output.
+.IP freed 4
+.IX Item "freed"
+This state is entered when the MD is freed.  It is the terminal state
+for all life-cycle transitions.
+.SS "State Transition Diagram"
+.IX Subsection "State Transition Diagram"
+The usual life-cycle of a MD is illustrated:
