# MTR "subroutine" which checks the output from mysqld --help
# --verbose to check if the deduced values for --basedir,
# --lc-messages-dir, --character-sets-dir and --plugin-dir have
# "reasonable" values. By reasonable is meant that the path exists and
# contains some key file/directory which is expected to be there.
#
# Note that the deduced value for --character-sets-dir and
# --plugin-dir is currently wrong when running from a sandbox build
# dir, so we just print the ok string anyway in this case
#
# Usage: Assign the MTR variable HELP_VERBOSE_OUTPUT to a file which contains
# the help output, then source this file.
