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.

+The ARC's idea of how much free memory is available to it, which is a bit less
+than
+.Sy free .
+May temporarily be negative, in which case the ARC will reduce the target size
