-# If you install MySQL on some other places than /usr, then you
-# have to do one of the following things for this script to work:
-#
-# - Run this script from within the MySQL installation directory
-# - Create a /etc/my.cnf file with the following information:
-#   [mysqld]
-#   basedir=<path-to-mysql-installation-directory>
-# - Add the above to any other configuration file (for example ~/.my.ini)
-#   and copy my_print_defaults to /usr/bin
-# - Add the path to the mysql-installation-directory to the basedir variable
-#   below.
-#
-# If you want to affect other MySQL variables, you should make your changes
-# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.
-
-# If you change base dir, you must also change datadir. These may get
-# overwritten by settings in the MySQL configuration files.
