 Resources were copied using make rules.  This is sensible in local
 machine builds but non-optimal in cluster builds.  It is entirely IO
-bound and the cluster aspect simply creates more IO as files need to
-be transferred over the network, possibly multiple times.  This change

+This happens at the end of each invocation of the build engine or "stage".
+Since resources are built in their own stage, the copying is completed
+before build tasks in the other stages require them.  The copied files
+are not needed in the resource stage itself.
 
+The filter uses <progress:end ...> tags to determine when a stage
+is finished and this requires that the timing feature be switched on
+permanently.
 
 The format of the tag is:
-<copy source="sourcefilename">dest_filename1 dest_filename2 ...</copy>
+<finalcopy source="sourcefilename">dest_filename1 dest_filename2 ...</finalcopy>
