-    parallel) until they are complete or we reach an error.  The

+    This is used when we find a tactic like *foo(...) but there
+    is no matching goal.  We run (in this callback) the associated
+    tactic code.  As long as it runs successfully, not returning 99 or
+    any error value, then we're OK - the tactic doesn't need rebuilding
+    so the dependency is satisfied.  However if it returns 99 (needs
+    rebuild) or an error then we have to exit with an error. *)
