sysexits 1.0.0

Have you ever wanted to call exit() with an error condition, but weren't sure what number to use? No? Maybe it's just me, then. Anyway, I was reading W. Richard Stephens's book _Advanced Programming in the UNIX Environment_, and I wanted to make my program exit with a reasonable exit code just like his C examples, but much to my chagrin, I couldn't find a 'sysexits' for Ruby! Well, for the other 2 people that actually care about this kind of thing, now there is!
