Right. It's just a precompiled executable and some data files (let's not go 
there as to why some morons would write code that *require* the datafile in 
the same directory as the executable... no, it's an OEM, so I have no 
control). And it needs to end up in /opt/smipmicfg-1.27.0. I'm still not clear 
on what some of the specfile directives mean, in spite of reading a lot of 
stuff online, so that's why some of the stuff that's probably incorrect.
