Mr. Beckingham is perhaps generous when he says the installation of apcupsd is straightforward; my experience, wanting to be thorough and make sure I fully understood what I was doing, was that I had to skim through most of the nearly-daunting manual just to come to the conclusion that, yes, for my simple needs installation was about as simple as Mr. Beckingham describes.
I say the manual is "nearly-daunting" not because it's incomprehensible but only because it is, as Mr. Beckingham also says, comprehensive. *Really* comprehensive. Apcupsd ain't your daddy's PowerChute; it's complicated and sophisticated, with, for example, the ability to control multiple machines over a network via one master machine that the UPS communicates with. The very good manual reflects this complexity and more. I'd recommend portions of this manual as a generic USB troubleshooting guide too.
But it doesn't make it simple to realize that using apcupsd for simple scenarios is really reasonably simple. And it's not as simple as you might hope because it has to modify shutdown scripts for various different distros, and a UPS-initiated shutdown is surprisingly involved, and if you're like me you feel compelled to check up on what it did and make sure you understand it all and that it's really going to work. It's not bad, but it's a bit more involved than "./configure ; make ; make install".
