-# This is for a system with little memory (32M - 64M) where MariaDB plays
-# an important part, or systems up to 128M where MariaDB is used together with
-# other programs (such as a web server)
-#
-# MariaDB programs look for option files in a set of
-# locations which depend on the deployment platform.
-# You can copy this option file to one of those
-# locations. For information about these locations, do:
-# 'my_print_defaults --help' and see what is printed under
-# Default options are read from the following files in the given order:
-# More information at: http://dev.mysql.com/doc/mysql/en/option-files.html

-# In this file, you can use all long options that a program supports.
-# If you want to know which options a program supports, run the program
-# with the "--help" option.
