+#
+# This perl script checks for availability of the Perl modules DBI and
+# DBD::MariaDB using the "current" perl interpreter.
+#
+# Useful for test environment checking before testing executable perl scripts
+# in the MySQL Server distribution.
+#
+# NOTE: The "shebang" on the first line of this script should always point to
+#       /usr/bin/perl, so that we can use this script to check whether or not we
+#       support running perl scripts with such a shebang without specifying the
+#       perl interpreter on the command line. Such a script is mysqlhotcopy.
+#
+#       When run as "checkDBI_DBD-MariaDB.pl" the shebang line will be evaluated
+#       and used. When run as "perl checkDBI_DBD-MariaDB.pl" the shebang line is
+#       not used.
+#
+# NOTE: This script will create a temporary file in MTR's tmp dir.
+#       If modules are found, a mysql-test statement which sets a special
+#       variable is written to this file. If one of the modules is not found
+#       (or cannot be loaded), the file will remain empty.
+#       A test (or include file) which sources that file can then easily do
+#       an if-check on the special variable to determine success or failure.
+#
+#       Example:
+#
+#         --let $perlChecker= $MYSQLTEST_VARDIR/std_data/checkDBI_DBD-MariaDB.pl
+#         --let $resultFile= $MYSQL_TMP_DIR/dbiDBD-MariaDB.txt
+#         --chmod 0755 $perlChecker
+#         --exec $perlChecker
+#         --source $resultFile
+#         if (!$dbidbd) {
+#             --skip Test needs Perl modules DBI and DBD::MariaDB
+#         } 
+#
+#       The calling script is also responsible for cleaning up after use:
+#
+#         --remove_file $resultFile
+#
+# Windows notes: 
+#   - shebangs may work differently - call this script with "perl " in front.
+#
+# See mysql-test/include/have_dbi_dbd-mariadb.inc for example use of this script.
+# This script should be executable for the user running MTR.
