#
# Coding style directions for this perl script
#
#   - To make this Perl script easy to alter even for those that not
#     code Perl that often, keeep the coding style as close as possible to
#     the C/C++ MySQL coding standard.
#
#   - All lists of arguments to send to commands are Perl lists/arrays,
#     not strings we append args to. Within reason, most string
#     concatenation for arguments should be avoided.
#
#   - Functions defined in the main program are not to be prefixed,
#     functions in "library files" are to be prefixed with "mtr_" (for
#     Mysql-Test-Run). There are some exceptions, code that fits best in
#     the main program, but are put into separate files to avoid
#     clutter, may be without prefix.
#
#   - All stat/opendir/-f/ is to be kept in collect_test_cases(). It
#     will create a struct that the rest of the program can use to get
#     the information. This separates the "find information" from the
#     "do the work" and makes the program more easy to maintain.
#
#   - The rule when it comes to the logic of this program is
#
#       command_line_setup() - is to handle the logic between flags
#       collect_test_cases() - is to do its best to select what tests
#                              to run, dig out options, if needs restart etc.
#       run_testcase()       - is to run a single testcase, and follow the
#                              logic set in both above. No, or rare file
#                              system operations. If a test seems complex,
#                              it should probably not be here.
#
# A nice way to trace the execution of this script while debugging
# is to use the Devel::Trace package found at
# "http://www.plover.com/~mjd/perl/Trace/" and run this script like
# "perl -d:Trace mysql-test-run.pl"
