+2.1) Running tests in parallel
+==============================
+
+  To speed up testing an alternative to 'verify.pl' is to generate a
+  Makefile that runs all the tests. The tests can then be executed
+  using the 'make' command with a number of parallel jobs. This can
+  significantly reduce the time it takes to run the regressions during
+  development. Note that running 'verify.pl' is the canonical way of
+  executing the tests and it should always be run before committing
+  any changes to the repository.
+
+  The Makefile can be generated by running the script 'verify.pl' with
+  the option '-M'. It is also possible to run only a subset of the tests
+  in parallel. For example: 'make systemc/communication -j8' will run
+  all tests in the 'systemc/communication' sub-category.
