After all tests have been performed, runscripts() prints some
performance statistics that are computed by the Benchmark module.
+=head2 The test script output
+
+Any output from the testscript to standard error is ignored and
+bypassed, thus will be seen by the user. Lines written to standard
+output that look like perl comments (start with C</^\s*\#/>) are
+discarded. Lines containing C</^(not\s+)?ok\b/> are interpreted as
+feedback for runtests().
+
+It is tolerated if the test numbers after C<ok> are omitted. In this
+case Test::Harness maintains temporarily its own counter until the
+script supplies test numbers again. So the following test script
+
+ print <<END;
+ 1..6
+ not ok
+ ok
+ not ok
+ ok
+ ok
+ END
+
+will generate
+
+ FAILED tests 1, 3, 6
+ Failed 3/6 tests, 50.00% okay
+
+The global variable $Test::Harness::verbose is exportable and can be
+used to let runscripts() display the standard output of the script
+without altering the behavior otherwise.
+
=head1 EXPORT
C<&runscripts> is exported by Test::Harness per default.
If all tests are successful some statistics about the performance are
printed.
-=item C<Failed 1 test, $pct% okay.>
+=item C<FAILED tests %s\n\tFailed %d/%d tests, %.2f%% okay.>
+
+For any single script that has failing subtests statistics like the
+above are printed.
+
+=item C<Test returned status %d (wstat %d)>
+
+Scripts that return a non-zero exit status, both $?>>8 and $? are
+printed in a message similar to the above.
+
+=item C<Failed 1 test, %.2f%% okay. %s>
-=item C<Failed %d/%d tests, %.2f%% okay.>
+=item C<Failed %d/%d tests, %.2f%% okay. %s>
If not all tests were successful, the script dies with one of the
above messages.
