 28 # If you install MySQL on some other places than /usr/local/mysql, then you
 29 # have to do one of the following things for this script to work:
 30 #
 31 # - Run this script from within the MySQL installation directory
 32 # - Create a /etc/my.cnf file with the following information:
 33 #   [mysqld]
 34 #   basedir=<path-to-mysql-installation-directory>
 35 # - Add the above to any other configuration file (for example ~/.my.ini)
 36 #   and copy my_print_defaults to /usr/bin
 37 # - Add the path to the mysql-installation-directory to the basedir variable
 38 #   below.
 39 #
 40 # If you want to affect other MySQL variables, you should make your changes
 41 # in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.

 44 # overwritten by settings in the MySQL configuration files.
