# Design of stress script should allow one:
#
# - To stress test the mysqltest binary test engine.
# - To stress test the regular test suite and any additional test suites
# (such as mysql-test-extra-5.0).
# - To specify files with lists of tests both for initialization of
# stress db and for further testing itself.
# - To define the number of threads to be concurrently used in testing.
# - To define limitations for the test run. such as the number of tests or
# loops for execution or duration of testing, delay between test
# executions, and so forth.
# - To get a readable log file that can be used for identification of
# errors that occur during testing.
