    Set up databases with:
        unset TMPDIR
        cd #{prefix}
        scripts/mysql_install_db --basedir=#{prefix}

    If this is your first install, automatically load on login with:
        cp #{prefix}/com.mysql.mysqld.plist ~/Library/LaunchAgents
        launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

    If this is an upgrade and you already have the com.mysql.mysqld.plist loaded:
        launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
        cp #{prefix}/com.mysql.mysqld.plist ~/Library/LaunchAgents
        launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

    Note on upgrading:
        We overwrite any existing com.mysql.mysqld.plist in ~/Library/LaunchAgents
        if we are upgrading because previous versions of this brew created the
        plist with a version specific program argument.

    Or start manually with:
        mysqld_safe &
    EOS
  end
