+There are two additonal local options: '--batch[n=x]' and '--time-profile'.
+
+If '--batch[n=x]' is used without '--time-profile', this script will call
+run_tests_in_batch.py` in order to run the tests by batches, not all at the
+same time. `run_tests_in_batch.py` will in turn call back this script in
+another process. The batches will comprise 100 elements each by default and
+x elements if the option 'n=x' is specified.
+
+If the '--time-profile' option is used, it will call `run_tests_in_batch.py`
+with the option time_profile=True to conduct time-profiling of the tests: Each
+test will be run and timed separately and the results will be deposited in the
+files 'timeprof_sort' and 'timeprof_nosort' whose location is specified in
+`run_tests_in_batch.py`. If the '--batch n=x' option is also specified,
+notification of the progresses will be made to standard output after every
+group of x tests.  Otherwise, notification will occur after every group of 100
+tests.
+
+The files 'timeprof_sort' and 'timeprof_nosort' both contain one record for
+each test and comprise the following fields:
+- test running-time
+- nosetests sequential test number
+- test name
+- name of class to which test belongs (if any), otherwise full
+  information is contained in test name
+- test outcome ('OK' or 'FAILED')
+
+In 'timeprof_sort', test records are sorted according to running-time whereas in
+'timeprof_nosort' records are sorted according to sequential number. The former
+classification is the main information source for time-profiling. Since tests
+belonging to same or close classes and files have close sequential numbers, the
+latter may be used to identify duration patterns among the tests. A full log is
+also saved as 'timeprof_rawlog''.
