+Skipping tests
+--------------
+
+If you need to skip all the remaining tests you should set skip_all
+and immediately call test_done. The string you give to skip_all will
+be used as an explanation for why the test was skipped. for instance:
+
+       if ! test_have_prereq PERL
+       then
+           skip_all='skipping perl interface tests, perl not available'
+           test_done
+       fi
 
 End with test_done
