 Regenerating test results
 =========================
 
+To update the test results, first the tests must be run as above.

 Giving -copy as the first argument to ../run_parser_all.sh or
 parser_tests.sh (or long_tests.sh or tex_html_tests.sh, which need
 environment variables LONG_TESTS resp. TEX_HTML_TESTS, or ALL_TESTS, to
 be set to "yes", but otherwise operate similarly) will cause the 
-reference results to be regenerated.  For example, to update the 
-reference results for one particular test:
+reference results to be copied from the results the last time the tests 
+were run.  For example, to update the reference results for one 
+particular test:
 
 $ ./parser_tests.sh -copy formatting
 The copy-* make targets update all the references for various large sets
