 the currently existing test cases, simply execute ./mysql-test-run in
 this directory. It will fire up the newly built mysqld and test it.

-
-mysql-test-run --extern alias analyze

mysql-test/README.gcov

 To be able to see the level of coverage with the current test suite,
 do the following:
 
-  - make sure gcov is installed
-  - compile with BUILD/compile-pentium-gcov ( if your machine is not pentium, hack
-this script, or just live with the pentium-specific stuff)
-  - ./mysql-test-run -gcov
-  - to see the level of coverage for a given source file:
+  - Make sure gcov is installed
+  - Compile the MySQL distribution with BUILD/compile-pentium-gcov (if your
+    machine does not have a pentium CPU, hack this script, or just live with
+	the pentium-specific stuff)
+  - In the mysql-test directory, run this command: ./mysql-test-run -gcov
+  - To see the level of coverage for a given source file:
      grep source_file_name /tmp/gcov.out
