APCUPSD can be used for power management and controlling most of APC's UPS models on Unix and Windows machines. Apcupsd works with most of APC's Smart-UPS models as well as most simple signalling models such as Back-UPS and BackUPS-Office. This buildscript veers from the "accepted" installation of apcupsd, but for what I believe you'll see are justifiable reasons. The stock install of apcupsd detects its presence on Slackware and attempts to patch the system's /etc/rc.d/rc.6 script and places the rc.apcupsd script inside /etc/rc.d (instead of DESTDIR/etc/rc.d - in essence, it touches files outside DESTDIR). I don't view this as even remotely acceptable, so the build script disables the distribution-specific installation to prevent messing with files outside DESTDIR; however, this does make it require some manual configuration after installation. After installing, see /usr/doc/apcupsd-3.14.13/README.SLACKWARE for more information on how to modify rc.6 and how to start the apcupsd daemon automatically at boot.
