    Set up databases to run AS YOUR USER ACCOUNT with:
        unset TMPDIR
        mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix percona-server)" --datadir=#{var}/percona --tmpdir=/tmp

    To set up base tables in another folder, or use a different user to run
    mysqld, view the help for mysqld_install_db:
        mysql_install_db --help

    and view the MySQL documentation:
      * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html
      * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html

    To run as, for instance, user "mysql", you may need to `sudo`:
        sudo mysql_install_db ...options...

    Start mysqld manually with:
        mysql.server start

        Note: if this fails, you probably forgot to run the first two steps up above

    A "/etc/my.cnf" from another install may interfere with a Homebrew-built
    server starting up correctly.

    To connect:
        mysql -uroot

    To launch on startup:
    * if this is your first install:
        mkdir -p ~/Library/LaunchAgents
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    * if this is an upgrade and you already have the #{plist_path.basename} loaded:
        launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    You may also need to edit the plist to use the correct "UserName".
