nls

linux下查看系统工具原码,如IOSTAT等

Answer y if you want to enable National language Support (NLS).
With NLS enabled, the sysstat utilities will behave in accordance with your
current locale. Sysstat messages will be translated into the language specified
by the LANG environment variable, among other.
Read the nls/README-nls file for more information.
So you should say y here.
