commit c999ab77f8dad6c6655007baebe9c7992d6fe206
Author: Mo Zhou <cdluminate@gmail.com>
Date:   Fri Jan 15 14:26:42 2021 +0800

    Move arcstat(1) to arcstat(8) to avoid conflict with binary package nordugrid-arc-client.
    We regenerate Makefile.in, so we don't have to modify them explicitly here.
